Validation.xml....need some help

[meena latha]

Hi,

I wanted to validate a input text field.
I am using validation.xml to do this.
This is what i have written in my validation.xml

<form name="storeRoomForm">
        <field property="itemNum" depends="required,validWhen">
     <arg0 key="error.invalid.itemnum"/>
       </field>
    </form> 

This works fine.But the problem is,i should not get the error message once the page is loaded .I should get it only when i hit the submit button.
How should i modify my validation.xml to do this.I should basically put
some check to see whether the submit button is hit or not.
Any help will be really useful.
Thanks.

Override the validate method and return null if the your submit button is not present in the request or is null(if present as a form parameter). If the submit button is pressed, return super.validate(arg0, arg1)

For e.g.

   
public ActionErrors validate(ActionMapping arg0, HttpServletRequest arg1) {
if(this.button.equalsIgnoreCase("[submit button name]")){
return super.validate(arg0, arg1);
}
return null;
}

Thanks for the reply.But when we are using the validation framework do we need to override the validation()..???

I dont see the harm in overriding the validation method for the question you asked.

Alternatively, If you have two action classes - one when the page first loads(ViewAction class) and the other for submitting or CRUD operations(UpdateAction class) then you can set the validate="false" for the first class.

No change needs to be done on the validation.xml. You need to have 2 actions in your struts-config.xml file.

For example:

<action path="/WhenPageLoad"
type="person.employee"
name="employee"
scope="request"
validate="false"
input="empl.page"
parameter="dispatch">
<forward name="nextScr" path="empl.page"
contextRelative="true"/>
</action>


<action path="/WhenSubmitClick"
type="person.employee"
name="employee"
scope="request"
validate="true"
input="empl.page"
parameter="dispatch">
<forward name="nextScr" path="empl.page"
contextRelative="true"/>
</action>

The validate="false" makes it by pass validation on page load.

Thanks.I have only one Action class thats the problem....However i have modified my validation.xml this way.

  
 
<form name="Form">
    <field property="itemNum" indexedListProperty="dependents"
    depends="requiredif">
    <arg0 key="error.item.invalid"/>
    <var>
    <var-name>field[0]</var-name>
    <var-value>formSubmitted</var-name>
    </var>
    <var>
    <var-name>field-test[0]</var-name>
    <var-value>EQUAL</var-value>
  </var>
    <var>
    <var-name>field-value[0]</var-name>
    <var-value>true</var-value>
  </var>
  </field>
  </form> 
 
  

But now i am getting the following error.

   
Cannot load a validator resource from '/WEB-INF/validator-rules.xml,                                               /WEB-INF/validation.xml'
 

what i am all doing is setting a property value to true when the submit button is clicked.Then i am checking that in my validation.xml.
Any suggestion is most welcomed.
Thanks

sorry the error got resolved .The problem was the the end tag for <var-value> was </var-name>.But the validation is not carried out.

Thanks to all.It is working.I modified the validation.xml .

    
 
<field property="itemNum" depends="requiredif"> 
       <arg0 key="error.invalid.itemnum"/> 
          <var>    
          <var-name>field[0]</var-name>
          <var-value>formSubmitted</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>true</var-value>
       </var>
       </field>
