Don Brown updated WW-2611:
--------------------------
Fix Version/s: 2.1.3
> s:action tag leaves invalid ActionInvocation in threadlocal ActionContext
> -------------------------------------------------------------------------
>
> Key: WW-2611
> URL: https://issues.apache.org/struts/browse/WW-2611
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.11.1, 2.1.1
> Reporter: Jeromy Evans
> Fix For: 2.1.3
>
>
> This tag sets up a new context and ActionInvocation and invokes the action
> and result correctly. The problem is that within that process XWork's
> DefaultActionInvocation replaces the ActionInvocation in the ThreadLocal
> ActionContext with the tag's own invocation:
> // Setting this so that other classes, like object factories, can use
> the ActionProxy and other
> // contextual information to operate
> ActionContext actionContext = ActionContext.getContext();
> if(actionContext != null) {
> actionContext.setActionInvocation(this);
> }
> The effect is that after completion of the tag, the ActionInvocation in the
> ThreadLocal ActionContext still references the tag's temporary invocation
> instead of the "parent" action's invocation. From that point, anything can
> happen, and does (WW-2079, WW-2290, WW-2599 and TagUtils.buildNamespace).
> I'm not sure how to fix this. Placing the ActionInvocation into a
> ThreadLocal goes against the the stack-based architecture of Struts2.
