That will only work if the value you're trying to pass is a string.
It might also add whitespace to either end of that value (due to the
whitespace inside your s:set tag.
Why not pass the OGNL expression to your tag as a string and evaluate
it inside your custom tag, instead? If you use this custom tag in
many places, I predict the extra jsp required to pre-evaluate the
OGNL->string will be error-prone...

I must add that s:set printed out the string as well. I am not quit sure
if its supposed to, but it did. Therefor I even had to encapsulate
s:property with a s:param statement. Like this
<s:iterator value="model.list">
<s:set name="value">
<s:param name="value">
<s:property value="top"/>
</s:param>
</s:set>
<custom:tag attr="${value}" />
</s:iterator>
This is quite a big block for little I wanted to achieve.
I thought about passing the whole list to the tag too, but somehow it
did not feel like the right thing to do, at least as I would have done
it. My understanding of struts is not as experienced so if I may ask,
why would I need an extra jsp to pre-evaluate the OGNL as string as you
proposed?
thx
