Value not returned to form inside logic:iterate

Currently, with the referenced code below, the selected value on the page IS NOT being saved on the ActionForm with the property listed. Any ideas as to why? Thanks to all!

<logic:iterate name="ReportListForm" property="reportChosen.groups" id="groups">
<logic:iterate name="groups" property="parms" id="parmValues" >
<c:set var="dataName" value="${parmValues.dataType}" />
<c:if test="${dataName=='multipleSelect'}">
<td>
<html:select indexed="true" size="10" name="parmValues" property="value" multiple="true">

<html

ptionsCollection name="parmValues" property="choicesList" />

</html:select>
</td>
</c:if>
</logic:iterate>
</logic:iterate>

terms explained
--------------------------------
ActionForm="ReportListForm"
reportChosen = Report class that stores information
groups = ArrayList property of Group types, property of reportChosen
parms = ArrayList property of Parm types, property of groups
dataType = lets me know which type of html element to created for user input
multipleSelect = identifier for a select list with multiple=true
choicesList = ArrayList of choices (type = LabelValueBeans to populate lists)
------------------------------------

Thanks for your assistance. I am stumped!

Since you have a loop within a loop, merely specifying indexed="true" with the <html:select> isn't going to work. With a more complex situation like this you either have to use the <nested> tags or build the indexed property name yourself.

If you use the Struts-el version of the tags, the following should work:

In addition to the above, you must also have indexed getters and setters for your properties. Also, if ReportListForm is in request scope, you will need to read this link carefully and follow its instructions for giving your lists "lazy initialization" behavior.

Merrill,

Once again you have proven your stuff. I followed your advice and created a basic structure like you suggested, and voila!, the values are stored.

Thanks again for your time and clear/concise response!!

You're very welcome. Good luck with your project.

could anyone help??
is there any tutorial or site that you know with relevant example code?

Hi, I am trying to save values of a select in a form. The select is inside 2 nested logic iterate tags similar to the solution provided below. I tried implementing it the same way but I get the following exception:

Invalid indexed property 'fileNumberBeans[indx.intValue()]' on bean class 'class com.test.OfaForm' Invalid index value 'indx.intValue()''

This is what I have in my JSP:

<logic:iterate id="fileNumberBeans" scope="request" type="com.test.FileBean" name="ofaForm" property="fileNumberBeans" indexId="indx">
<logic:notEmpty name="fileNumberBeans">
<tr>
<td class="TableBorder">
<table id="<bean:write name="fileNumberBeans" />">
<logic:iterate id="offBn" name="fileNumberBeans" type="com.test.OfaSDOBean" property="singleDefBeans" indexId="ix">
<tr>
<td id="<bean:write name="offBn" />" align="left" width="310px" class="TableBorder">
<bean:define id="offDetailSelectList" name="offBn" property="offDetailSelectList" type="java.util.ArrayList" />
<html:select styleClass="ListBox" property="fileNumberBeans[indx.intValue()].offBn[ix.intValue()].offDetail" name="ofaForm" size="1" >
<html

ptions collection="offDetailSelectList" property="value" labelProperty="label" />
</html:select>
</td>
</tr>
</logic:iterate>
</table>
</td>
</tr>

</logic:notEmpty>
</logic:iterate>

Any help on this will be greatly appreciated.
