Re: Struts2.1.8.1, s:push does not return s:property value
The pushed object will be on the stack while the tag is evaluated (in
the tag body), and it will be popped after the end of the tag, so
<s:push value="%{'not now john'}">
<s:property value="%{top}"/> <--- will print 'not now john'
<s:push>
<s:property value="%{top}"/> <--will print whatever was in the top of
the stack, before the "push" tag was invoked

Sorry the example does shown within the push tag.

Thank you Musachy.
If I am right, the example in the tutorial does not work.
Working codes:
================
<s:push value="artist">
Artist Name:<s:property value="name" /> <BR/>
Artist Bio: <s:property value="bio" /> <BR/>
</s:push>
*Not* working codes shown in the link:
>>http://www.vaannila.com/struts-2/struts-2-example/struts-2-push-tag-example1.html
====================================================
<s:push value="artist" />
Artist Name:<s:property value="name" /> <BR/>
Artist Bio: <s:property value="bio" /> <BR/>
Push an object, and then retrieve the object's attribute outside s:push
tag will not work (have to use artist.name).
