How to retain value in struts 2 using <s:select></s:select> tag

Hi,
I am trying to retain selected values in .jsp using select tag but I could not get proper solution.Can anyone help with the better solution for this.

Thanks in advance...!

hi,

Declare your select tag like ..

<s:select theme="simple" cssClass="textfield"
headerValue="Select Region" headerKey="0"
name="region.categoryId"
value="%{categoryId}" list="regionList"
listKey="categoryId" listValue="categoryName" />

That's it.

just make sure your listKey and value filed match property name you have give to it.

Like here it is listKey="categoryId" and for select give it to value categoryId .

that will make your select box value selected.

I am still suffering with same problem

<s:select name="companyList" headerKey="-1" headerValue="--Select--" value="{companyCode + ',' + branchCode}" listKey="{companyCode + ',' + branchCode}" listValue="company + ' ' + branch" list="%{#session.COMPANY_LIST}" />

generally i am sending the addition of two values as key

Hi,

I want to know this select tag is working fine at your end.

because I have seen this type of field {companyCode + ',' + branchCode} first time.

Yes it is working fine, (+) is an OGNL expression used for addition of two values.

apart from that is anything wrong in my code

Hi,

if you want to add like {companyCode + ',' + branchCode}"

then why you use ',' in between companyCode and branchCode.

Simple addition can looks like "{companyCode + branchCode}"

may be like that.

Actually, key sent from jsp is separated using " , " in action class and stored in string[ ] and then using these keys value data is retrieved from database.

Hi,

Actually you listKey="" attribute and value="" attribute must match.

If you write in listKey="" with " , " comma separated then your value="" attribute not match with your listKey="".

so make it same.

i did not understand it can you explain it more clearly please

hi,

Key your code as it is just change ...

Just change in value="%{companyCode + ',' + branchCode}"

add

%

at front value tag.

see above.

Sorry boss.......................!

sitll as usual

@Nishan: There's no reason the listKey and listValue have to be the same format.

@Sai: How are you declaring the action's companyList property?

I am declaring it as list< Company Object>

Company object has four properties

companyCode

branchCode

company

branch

Hi David,

Can you Help me with the solution.

#session.COMPANY_LIST is meaningless--you either need to use something like:

#session[@complete.pkg.reference@COMPANY_LIST]

or

#session['companyList']

or something else that makes sense. Other than that it should be fine.

By using the same #session value i am getting the values from session and is displayed in drop down list also, even the codes are displayed when tried to print.

Only problem is it is not retaining. :thumbup:

COMPANY_LIST is the key for the list<Company Object> stored in session

What do you mean, "not retaining"?

After refreshing the value in the select option should be the same as selected....... this is what i am trying for

If you have a setter for companyList in the action, and it contains the values you want "pre-selected", then it should work fine.

Hi Sai

is your drop down coming from a list or its a static drop down ?

No, it is the list that is generated in action class from database

i faced the same problem sometime back.

i was using Map and it looked something like

countryMap.put(capital+"."+code,name);

and then separated capital and code using split method.

Ya me to doing the same logic for separating company code and branch code. but the logic is in action class. everything is working fine.

problem is value is not retained.

Sai can you be more clear on what you exactly mean by value is not retained.

when i select a value in drop down and click submit button i get related data in the table, but the selected option is not displayed in drop down list. it shows the default value " -- Select -- "

can you use autocompleter instead of select tag.

For example if your autocompleter name is fruit

then in your action class declare 2 fields

String fruit;
String fruitKey; and make getter and setter for them. Your problem will be solved.

@bilal: Not using an autocompleter isn't the issue.

@David: I said this because i faced the same problem and i rectified it by using autocompleter.

That may be, but a whole bunch of us use <s:select...> with no issues. Switching to an autocompleter brings its own set of issues, and the Dojo tags are deprecated and won't always be around.

Please anyone can help me out with the sample code please

Lets wait for some one to place a code for select tag.

if incase anytime you want to shift on autocompleter i can give you the code.

ya will try with that also can you
please help me

This part comes in jsp page (EditStudentInfo.jsp)

xml

Action class (insertEditStudentInfo.java)

Method to populate country, this part of code is also from action class, i am adding 2 countries hard coded, you can add them dynamically. and call this method in execute method.

If still you face any problem feel free to send a message.
