You've got a number of bugs here.
The first (not technical, more for human understanding) is that there
are too many ambiguities. If you want to write ognl, tell the compiler
that.
Another is that a one-character sequence denoted with '' is a char, not
a string. If you want it to be a string, denote it with "" (and in
order to do so, quote the full attribute value with '' instead of "").
Another is that you're not fetching the value from the right namespace.
Values "set" in the valuestack are not on the stack but in a related
hashmap, and you tell OGNL to look up a value in that instead of against
the stack with the # character.
Try this:
<s:iterator value='%{{"a","b"}}' var="v">
<s:property value="%{#v}"/>
</s:iterator>
As another poster noted, the iterator tag pushes the current iteration
value on top of the stack, so this should be equivalent:
<s:iterator value='%{{"a","b"}}'>
<s:property />
</s:iterator>
(Note, I didn't actually try these bits of code, and when I just grepped
through my current project's codebase I didn't see %{} wrapped around
the only two places where I use the list construction syntax {,,}...
...so if it doesn't work, I'd start by questioning that. :-)
