Re: Accessing the wrapped context from a tag file.

Thanks.  I guess I'll write the tag... bummer.   I suspect that the 
'outer' scope should be made available, surely there will be other use 
cases for it.

Hi all,

I have a simple jsp that I used to include statically to pages when I 
needed to see what variables were in all of the implicit objects 
(parameters, session etc).  For example:
<table>
<c:forEach items='${pageScope}' var='page'>
      <tr><th>${page.key}</th><td>${page.value}</td></tr>
</c:forEach>
</table>

Now I want to convert it to a tag file, but the problem is that the 
pageScope inside a tag file is a fresh clean pageScope, as demanded 
by the Spec.  I want access to the original pageScope as well.    Any 
one know if this scope is available via the EL?


This doesn't really have anything to do with EL.  You can't access 
this other scope.  Alternatives might be:
1. iterate through the pageContext attributes and store them in a Map 
in a request attriubte.
2. create a custom tag instead of an include file.  then the tag would 
exist in the same page scope.
3. do a static include, so you're just inlining that separate file and 
you stay in the same page scope.
