Embedded <s:iterator/> problem
------------------------------
Key: WW-1988
URL: https://issues.apache.org/struts/browse/WW-1988
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.0.6
Environment: Apache Tomcat 5.5, Java 1.6, Windows XP
Reporter: sherry
First, you can look through next jsp codes:
<s:iterator status="stat" value="destObjects">
<tr>
<s:iterator value="visibleColumns">
<td>
<s:property value="destObjects[%{#stat.index}].%{fieldDefName}" />
</td>
</s:iterator>
</tr>
</s:iterator>
Variable "destObejcts" is a <LIST> type which contains a serial of objects
named "destObject".
Variable "visibleColumns" is also a LIST of objects named "visibleColumn", and
"fieldDefName" is a property of "visibleColumn".
And thus value of expression "visibleColumn.fieldDefName" will be a property
name of object "destObject".
Above relationship between two objects sounds a bit boring. As a trouble, I
failed to get the correct values of these dynamic fields of "destObejct", and I
had tried in many ways, and next Struts2 expressions ALL could not work:
<s:property value="destObjects[%{#stat.index}].%{fieldDefName}" />
<s:property value="%{destObjects[#stat.index].%{fieldDefName}}" />
<s:property value="%{fieldDefName}" />
OR
<s:iterator value="destObjects" id="do">
<s:iterator value="visibleColumns" id="vc">
<s:property value="#do.%{vc.fieldDefName}"/>
</s:iterator>
</s:iterator>
However, if I specify a real fieldname out of the second iterator tag, it does
work:
<s:property value="destObjects[%{#stat.index}].field1" />
