OGNL dynamic access map with iterator var

I'm trying to access a map using OGNL, and I can't really access the map using the iterator var, but I can access it using the status.

Basically, this works:

<s:iterator value="categories" var="citem" status="stat">
<s:property value='catColors[#stat.count]' />
<s:property value='#citem.id]' />
</s:iterator>

This won't work:

<s:iterator value="categories" var="citem" status="stat">
<s:property value='catColors[#citem.id]' />
</s:iterator>

I can't really find out why. Any help is appreciated :)

Try this.

<s:iterator value="categories" var="citem" status="stat">
<s:property value='catColors[[0].id]' />
</s:iterator>

In struts [0] gets the current iterated value on the stack, which in your example would be the same as the "citem".

I am guessing that you are trying to get the catColors[] indexed at "id".
