Searching for some more documentation on net about OGNL and its connection
to WW/Struts2, I think I finally isolated what was causing some confusion in
my case. Since it may useful for some other newbies, here is what works in
the situation from the previous post:
<s:text name="%{#attr['title']}"/>
This doesn't work:
<s:text name="#attr['title']"/>
because unlike in <s:properties> and some other tags, in <s:text> %{...}
cannot be omitted.
This wouldn't work either:
<s:text name="%{attr['title']}"/>
because unlike variables, for non-root objects in WW and Struts2 prefix #
cannot be omitted.
The reasons become pretty clear after one digs deeper into OGNL in WW/S2...
but let's not make the post too big :)
Regards,
Dj.

Wesley - yes, that's it. Thanks for both clarifying my question and
answering it. :)
Now, this really solves the problem when the property is on value stack. Is
there a way to access other (non-root) objects using this notation? E.g. I
have attribute "title" defined in Tiles, also with a key rather than the
direct text. In the layout I do:
<tiles:importAttribute name="title" />
Normally, I could access this using #attr['title'], but the same problem
appears with <s:text>. Sure, I can always solve it by putting it value to
stack first before using %{...}, but I'd really like to avoid that step if
it is not necessary.
I would appreciate if you could send me off-list the post about OGNL.
Thanks!
Dj.

I could be wrong, but you may be misunderstanding the poster's intent. He
has a variable on the value stack that indicates which property key he wants
to retrieve. If my understanding is correct, then I would not really be any
help, but has the OP tried:
<s:text name="%{myKey}" />
?
P.S. I have a post from last week or before where I had a bunch of trouble
understanding OGNL and it might help you if you want it off-list.
