On htm:multibox

[Hiroyuki Suzuki]

hello again...

I have this situation, If radio button A is chosen, it will require to choose from the multibox (I have 5 boxes).
Now, I used requiredif to validate multibox: bitratebox[0] to bitratebox[4]..
Sample validation.xml

  
   <field property="fiveHundredKTxt" depends="requiredif"> 
      <arg name = "requiredif" key = "「500K用ファイル名」を入力" resource = "false" position="0"/>
      <var>   
        <var-name>field[0]</var-name> 
        <var-value>bitratebox[0]</var-value>   
      </var>
      <var>   
        <var-name>fieldTest[0]</var-name> 
        <var-value>EQUAL</var-value>   
      </var>
      <var>   
        <var-name>fieldValue[0]</var-name> 
        <var-value>500k</var-value>   
      </var>     
  </field>

problem is, when i do not select bitratebox[0], validation is not performed
even if I selected other bitrateboxes..in other words, bitratebox[0] should also be selected in order to perform validation.

Am I missing something here?

How do I used multibox array? I mean how do I access the index of the array?

Please help me...

Arigatou!

hello there again..
let me elaborate my question because i find it complicated.. :=)

The multibox property "bitrate" has 5 possible values in order{"500k","1M","2M","5M","6M"}
I can select any number of bitrate.

Question 1: if i choose to check 500k and 2M, the value of bitrate is
bitrate[0] = "500K"
bitrate[1] = "2M" ?

Now, after Ive selected 500K and 2M, i have to validate corresponding textbox for this bitrate.

Question 2: Im planning to do it this way on Validation.xml

for 500K validation,
i used bitrate[0] because its the only possible location for 500K..(dnt know if my idea is correct)

    
<field property="fiveHundredKTxt" depends="requiredif"> 
  <arg name = "requiredif" key = "「500K用ファイル名」を入力" resource = "false" position="0"/>
  <var>   
    <var-name>field[0]</var-name> 
    <var-value>bitratebox[0]</var-value>   
  </var>
  <var>   
    <var-name>fieldTest[0]</var-name> 
    <var-value>EQUAL</var-value>   
  </var>
  <var>   
    <var-name>fieldValue[0]</var-name> 
    <var-value>500K</var-value>   
  </var>     
</field>  

For 2M validation
i used bitrate[0],bitrate[1],bitrate[2] because i thought its the possible locations for 2M

    
<field property="twoMTxt" depends="requiredif"> 
  <arg name = "requiredif" key = "「2M用ファイル名」を入力" resource = "false" position="0"/>
  <var>   
    <var-name>field[0]</var-name> 
    <var-value>bitratebox[0]</var-value>   
  </var>
  <var>   
    <var-name>fieldTest[0]</var-name> 
    <var-value>EQUAL</var-value>   
  </var>
  <var>   
    <var-name>fieldValue[0]</var-name> 
    <var-value>2M</var-value>   
  <var-name>field[1]</var-name> 
    <var-value>bitratebox[1]</var-value>   
  </var>
  <var>   
    <var-name>fieldTest[1]</var-name> 
    <var-value>EQUAL</var-value>   
  </var>
  <var>   
    <var-name>fieldValue[1]</var-name> 
    <var-value>2M</var-value>   
  </var>     
  <var-name>field[2]</var-name> 
    <var-value>bitratebox[2]</var-value>   
  </var>
  <var>   
    <var-name>fieldTest[2]</var-name> 
    <var-value>EQUAL</var-value>   
  </var>
  <var>   
    <var-name>fieldValue[2]</var-name> 
    <var-value>2M</var-value>   
  </var>     
  <var>
    <var-name>field-join</var-name>
    <var-value>OR</var-value>
  </var>
</field>

Is this possible? because its not working for me, maybe i miss something.

also i declare bitrate in my Action form as

    
private String[] bitratebox;
public String[] getBitratebox() {
  return bitratebox;
}
public void setBitratebox(String[] bitratebox) {
  this.bitratebox = bitratebox;
}

and my jsp is

  
<tr>
  <td><html:multibox property="bitratebox" value="500k"/>500k</td>
  <td><html:text property="fiveHundredKTxt"/></td>
</tr> 
<tr>
  <td><html:multibox property="bitratebox" value="1M"/>1M</td>
  <td><html:text property="oneMTxt"/></td>  
</tr>
<tr>
  <td><html:multibox property="bitratebox" value="2M"/>2M</td>
  <td><html:text property="twoMTxt"/></td> 
</tr>
<tr>
  <td><html:multibox property="bitratebox" value="5M"/>5M</td>
  <td><html:text property="fiveMTxt"/></td>
</tr>
<tr>
  <td><html:multibox property="bitratebox" value="6M"/>6M</td>
  <td><html:text property="sixMTxt"/></td>
</tr>

Please help me..im doing this for almost a day..
Its hard to be newbie.. :=)

Hiroyuki,

I warned you when I first told you about the validwhen validation rule that it does not cover complicated scenarios. It appears that your requirement is too complicated for validwhen to handle. You have two options:

1- You can override the validate(..) method in your ActionForm class and write your own logic for this validation. You can still perform the Validation Framework validations by calling super.vaidate(...).

2- You can write a custom validation rule. The validator guide has instructions on how to do this as well as an example.

Hello Everybody..
Hello Merril...

Im using requiredif.. it seems to be working a little bit but not successfully..

My friend suggested to use iteration on my multibox..
Based from the tutorials I've read which is something like this

    
<logic:iterate id="item" property="items">
    <html:multibox property="selectedItems">
        <bean:write name="item"/>
    </html:multibox>
        <bean:write name="item"/>
</logic:iterate>

I want to convert my jsp like the above format

My JSP looks like this

   
<tr>
  <td><html:multibox property="bitratebox" value="500k"/>500k</td>
  <td><html:text property="fiveHundredKTxt"/></td>
  <td><html:multibox property="fiveHundredK" value="goohigashi"/></td>
  <td><html:multibox property="fiveHundredK" value="goonishi"/></td>
  <td><html:multibox property="fiveHundredK" value="gooBB"/></td>
</tr> 
<tr>
  <td><html:multibox property="bitratebox" value="1M"/>1M</td>
  <td><html:text property="oneMTxt"/></td>  
  <td><html:multibox property="oneMmulti" value="goohigashi"/></td>
  <td><html:multibox property="oneMmulti" value="goonishi"/></td>
  <td><html:multibox property="oneMmulti" value="gooBB"/></td>
</tr>
<tr>
  <td><html:multibox property="bitratebox" value="2M"/>2M</td>
  <td><html:text property="twoMTxt"/></td> 
  <td><html:multibox property="twoMMulti" value="goohigashi"/></td>
  <td><html:multibox property="twoMMulti" value="goonishi"/></td>
  <td><html:multibox property="twoMMulti" value="gooBB"/></td>
</tr>
<tr>
  <td><html:multibox property="bitratebox" value="5M"/>5M</td>
  <td><html:text property="fiveMTxt"/></td>
  <td><html:multibox property="fiveMMulti" value="goohigashi"/></td>
  <td><html:multibox property="fiveMMulti" value="goonishi"/></td>
  <td><html:multibox property="fiveMMulti" value="gooBB"/></td>
</tr>
<tr>
  <td><html:multibox property="bitratebox" value="6M"/>6M</td>
  <td><html:text property="sixMTxt"/></td>
  <td><html:multibox property="sixMMulti" value="goohigashi"/></td>
  <td><html:multibox property="sixMMulti" value="goonishi"/></td>
  <td><html:multibox property="sixMMulti" value="gooBB"/></td>
</tr>

wherein "bitratebox" is the multibox Im trying to validate..

I tried to code the above JSP using iteration..
and I made this

  
<logic:iterate id="item" property="items">
  <tr>
    <td>
      <html:multibox property="bitratebox">
        <bean:write name="item" property="value"/> 
      </html:multibox>
      <bean:write name="item" property="label"/> 
    </td>
    <td><html:text property="fiveHundredKTxt"/></td>
    <td><html:multibox property="fiveHundredK" value="goohigashi"/></td>
    <td><html:multibox property="fiveHundredK" value="goonishi"/></td>
    <td><html:multibox property="fiveHundredK" value="gooBB"/></td>
  </tr>      
  <tr>
    <td>
      <html:multibox property="bitratebox">
        <bean:write name="item" property="value"/> 
      </html:multibox>
      <bean:write name="item" property="label"/> 
    </td>
    <td><html:text property="oneMTxt"/></td>  
    <td><html:multibox property="oneMmulti" value="goohigashi"/></td>
    <td><html:multibox property="oneMmulti" value="goonishi"/></td>
    <td><html:multibox property="oneMmulti" value="gooBB"/></td>
  </tr>
  <tr>
    <td>
      <html:multibox property="bitratebox">
        <bean:write name="item" property="value"/> 
      </html:multibox>
      <bean:write name="item" property="label"/> 
    </td>
    <td><html:text property="twoMTxt"/></td> 
    <td><html:multibox property="twoMMulti" value="goohigashi"/></td>
    <td><html:multibox property="twoMMulti" value="goonishi"/></td>
    <td><html:multibox property="twoMMulti" value="gooBB"/></td>
  </tr>
  <tr>
    <td>
      <html:multibox property="bitratebox">
        <bean:write name="item" property="value"/> 
      </html:multibox>
      <bean:write name="item" property="label"/> 
    </td>
    <td><html:text property="fiveMTxt"/></td>
    <td><html:multibox property="fiveMMulti" value="goohigashi"/></td>
    <td><html:multibox property="fiveMMulti" value="goonishi"/></td>
    <td><html:multibox property="fiveMMulti" value="gooBB"/></td>
  </tr>
  <tr>
    <td>
      <html:multibox property="bitratebox">
        <bean:write name="item" property="value"/> 
      </html:multibox>
     <bean:write name="item"property="label"/>                             
    </td>
    <td><html:text property="sixMTxt"/></td>
    <td><html:multibox property="sixMMulti" value="goohigashi"/></td>
    <td><html:multibox property="sixMMulti" value="goonishi"/></td>
    <td><html:multibox property="sixMMulti" value="gooBB"/></td>
  </tr>
</logic:iterate>

My Action Form

    
private String[] bitratebox = {};
private String[] items = {"500k","1M","2M","5M","6M"};
public String[] getBitratebox() {
  return this.bitratebox;
}
public void setBitratebox(String[] bitratebox) {
  this.bitratebox = bitratebox;
}

Are my codes correct??
this is the error

   
java.lang.NullPointerException: 空の属性名です
which means 
It is an empty attribute name. 

Please help me with the correct code..
Thank you..

Hello everyone..

forget about my question above, ive already made a solution for multibox

my JSP

    
<logic:iterate name="metaEntryConfirmForm" indexId="index"  id="item1" property="items1">                          
<tr>                            
  <td>
    <html:multibox property="bitratebox">
      <bean:write name="item1"/>
　　</html:multibox>
  </td>
  <td><html:text property="bitrateTxt"/></td>
  <td><html:multibox property="haishinselect" value="<%="goohigashi"+index%>"/></td>
   <td><html:multibox property="haishinselect" value="<%="goonishi"+index%>"/></td>
   <td><html:multibox property="haishinselect" value="<%="gooBB"+index%>"/></td>      
</tr>
</logic:iterate>

I only made 1 iteration which produces
5 rows and each row contains 1 checkbox, 1 text box and 1 multibox

my ActionForm

    
private String[] bitratebox = {};
private String[] items1 = {"500k","1M","2M","5M","6M"};
public String[] getBitratebox() {
return this.bitratebox;
}
public void setBitratebox(String[] bitratebox) {
this.bitratebox = bitratebox;
}
public String[] getItems1(){
return this.items1;
}

Now I will start the validation method..hope I can make it works..

[Hiroyuki Suzuki]

Before I proceed to validation..I encountered strange result again with my
multibox "bitratebox".
The selected box does not reflect on the next page when I submit the form.
Do I miss something in my logic:iteration method?

Please help me..

[Hiroyuki Suzuki]

Gomen nasai..Im sorry
Dont mind again the question above..
I just made some mistakes on my JSP..

Thank you..

[Ranjit Gopinathan]

In your second page, check if the "bitratebox" variable in the actionform is having the values selected in the previous page.

[Hiroyuki Suzuki]

Thanks for answering..I already resolved this problem..
arigatou!

[Gopinath Chinnakaruppan]

Hi,

I am also looking for similar functionality. When i select a value from drop down. I need to show fields to search depending on the selection.

label1 operator1(dropdown) value1(text/dropdown)
label2 operator2(dropdown) value2(text/dropdown)
label3 operator3(dropdown) value3(text/dropdown)
label4 operator4(dropdown) value4(text/dropdown)

The no of rows will be vary. Right now I have the changed the visibility of the values.

<tr>
<td>Name1  </td>
<td><html:select property="operator1">
<option value="SEARCH_OP_EQUAL" selected>= (equals)</option>
<option value="SEARCH_OP_CONTAINS">like</option>
</html:select> </td>
<td><html:text property="value1" /></td>
</tr>





<tr>
<td>Name2  </td>
<td><html:select property="operator2">
<option value="SEARCH_OP_EQUAL" selected>= (equals)</option>
<option value="SEARCH_OP_CONTAINS">like</option>
</html:select> </td>
<td><html:text property="value2" /></td>
</tr>

How can i use logic iterate to achieve this accordingly.

Please help me out.
