Re: nested tags
Nested tags rock whereas logic tags, while perhaps doing
the same thing are more cumbersome.
Scoping is much more intuitive - instead of having to talk
about 'myForm.myContainer.myObject, you can just
use nested:iterate and nested:nest to make your code
much easier to read. And, since you can write snippets
to the more localized scope, they can be reused on multiple
pages.
And, if that wasn't enough, you can do recursion with nested.
See the www.keyboardmonkey.com site for examples, etc.

Re: nested tags
Posted by arvind ramaswami <ar...@yahoo.com>.
Nested tags rock, as you have to deal with only one
level in the heirarchy at a time. I have been running
into some problems using nested tag for recursion,
though. I thought you might help me out while we are
on same subject.
My questions are :
1. Does the nested tag lib require struts to be used ?
I have nested-tag.jar and struts.jar in the
WEB-INF/lib but the application is not based on struts
framework. It is an MVC app but with our own
controller servlet and mapping(like struts-config).
When I tried, I got this dreaded error :
Cannot find message resources under key
org.apache.struts.action.MESSAGE'
javax.servlet.ServletException: Cannot find message
resources under key org.apache.struts.action.MESSAGE
at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:494)
This makes me wonder if struts framework is actually
needed for nested tags. Any help would be
appreciated..
2. I can't do a <nested:define> in my included JSP as
I get a null pointer exception.
Main jsp :
<nested:root name="docs">
<nested:nest property="treeNode">
<nested:iterate property="childCollection">
<jsp:include page="docnode.jsp" />
</nested:iterate>
</nested:nest>
</nested:root>
docnode.jsp (this recurses):
<nested:root>
<nested:equal property="showChildren"
value="true">
<nested:define id="imgState"
value="open18x16.gif" />
</nested:equal>
<!-- restof html code-->
<nested:iterate property="childCollection">
<jsp:include page="docnode.jsp" />
</nested:iterate>
</nested:equal>
</nested:root>
What am i doing wrong?
thanks
