Struts2 ScopeInterceptor scope.type end problem

[Volker Krebs <vo...@abas.de>]

Hello,
I've made an small workflow using the ScopeInterceptor.
All works fine, but I have one small problem, where I want to discuss a
solution.
My last action is defined as scope.type=end

<action name="showConfirmation" class="MyAction">
  <interceptor-ref name="myScopeStack">
    <param name="scope.type">end</param>
  </interceptor-ref>
  <result name="input">/confirm.jsp</result>
</action>

on the confirm.jsp I have no access to the objects which the
ScopeInterceptor was managing, because for scope.type=end actions
everything is cleared.

Any best practice for this (common) problem ?
Make an extra finish action that copies the scope objects to the
request ?

Any suggestions ?

Thanks
Volker

Hello,
yes the problem is that all scope objects managed by the scope
Interceptor will be cleared if the scope.type is "end".

I was looking for a way to copy it to the request, so that I could
display a confirmation/summary on the last page involved in my scope.

But the ScopyInterceptor does not set the scope objects to my Action if
the scope.type is "end".
Take a look at the beforeResult implementation in ScopeInterceptor.
I have no chance to access the scope Objects in an "end"-Action.

And ScopeInterceptor is not applicable for extension, since it has to
many private Fields/Methods.

Thanks,
Volker

Once you action execution is done all the valueStack objects will be cleared.
This is might be causing the problem. And can you please elaborate your
requirements.
