Hi friends,
I wish successes to everybody!

My question is such:

When i change the value of the following code (value=”0″) that is shown in the situation to checked
But when i click the submit button nothing is generated so how to get my page on checked state?

[U]JSP side:[/U]
<html-el:checkbox name=”scriptGeneratorForm”
property=”classPropertyList[${ctr}].selected”
styleId=”classPropertyList[${ctr}].selected” value=”1″
tabindex=”1″/>

[U]Program side:[/U]
List<ClassProperty> mainList = new ArrayList<ClassProperty>();
for (int i = 0; i < classPropertyList.size(); i++) {
ClassProperty classProperty = (ClassProperty) classPropertyList.get(i);
if (classProperty.getSelected() == 1) {
mainList.add(classProperty);
}
}

Thanks beforehand!

@RizvanauthorJan 14.2009 — Dear friends,

[B]I also want to add about my JavaScript code therefore sorry which i did not write at first:[/B]

<logic-el:iterate id="classProperty"

name="<&#37;=AdminConstantKeys.CLASS_PROPERTY_LIST_SESSION_KEY%>"

type="az.admin.model.ClassProperty" indexId="ctr">

<html-el:hidden property="classPropertyList[${ctr}].propertyName"
styleId="classPropertyList[${ctr}].propertyName"/>
<tr>
<td width="50" align="center">
[B]<html-el:checkbox name="scriptGeneratorForm"
property="classPropertyList[${ctr}].selected"
styleId="classPropertyList[${ctr}].selected" value="0"
tabindex="1"/>[/B]
</td>
I don't understand that why it isn't generated with checked state...?

Thanks again.

@FangJan 14.2009 — The [I]value[/I] has nothing to do with the checked state.

The generated code is invalid; the hidden controls can not be placed between <tr> elements.

The form must validate for name/value pairs to be returned correctly.

There is no JavaScript in your code, only server side coding.

Success!
