[OS-webwork] Using the PushTag

[Frederick N. Brier]

I cannot find an example the syntax to pass as the value attribute of the 
<ww:push> tag to retrieve an attribute from the 
HttpServletRequest.  Further, it looks as if the PushTag calls the 
ActionContext to retrieve the valueStack.  According to my debugger, the 
stack is empty.  Can the PushTag be used from a Sitemesh Decorator since it 
is not within the execution of an Action?  I cannot follow where in the 
code a translation of "$req.home" would become a lookup of the request 
attribute "home".  I do see where the ActionTag put(s) multiple values in a 
context map in createExtraContext(), but do not understand how it 
works.  Thank you.

I will try the push tag.  Thank you again.  BTW, would it be silly to have 
a filter that does nothing but clear the ActionContext ThreadLocal variable?

What are you trying to do in your decorators? If you access things in the 
request, where the Action will be bound with its id, you can push this 
action onto the ValueStack using the ww:push tag and use all of the other 
tags as normal.

I don't think we're going to make the ActionTag leave its ActionContext 
out there. It needs to be returned to the original.
