Yes, I will add a template keyword as well. Must admit that I interpreted
the Rundata.screen as a template in Jetspeed - it was only a few days ago
that I realized there is a ScreenTemplate which I should have used
instead... Do you think the screen parameter should be removed so that
there is only "template" and "action"?
Regarding QueryData and PathInfo, I don't really know what it is exactly
used for. Is there any document explaining it (apart from the source code
;-) )? It looks as if it changed class variables and then it wouldn't make
sense to set it via own tags as the object would be destroyed after the tag
has been called. And you certainly don't want to hold a reference to a
dynamicUri object within a Jsp.
So it could only be another (optional) parameter for the DynamicUriTag and
I'm not sure if this makes sense?
