Extension issues
Hi:
I think Struts is coming up with several interesting extensions:
-Tiles
-Validator
-Workflow
The bad thing is that you have to use appropriate ActionServlet
implementation for each extension.
Therefore you cannot, theoratically, use tiles for multiple view
reppresentation, validator for form calidation
and control flow with workflow extension at the same time. Did I
misunderstood anything? If not, is there a
way to work around?
Regards,
Antony

Thanks. That would be a lot of work though;-)

Hello,
It is something that Struts have to improve. The new "plugin" capabilities is
the first step, but doesn't solve everything yet.
What you can do is to provide your own ActionServlet implementation combining
features from the extensions you need.
Extend one of the actionServlet (the more complicated one ;-) ), and add
missing stuff from others.
From Tiles and Struts1.0, you need to pick up the init method, and catch any
call to RequestDispatcher.include() and RequestDispatcher.forward(). Check Tiles
servlet implementation : processActionForward() and processValidate() are copies
of original Struts implementation, except the call to include which is modify to
a call to a new method processForward().
If you use Struts1.1, you need to provide a RequestProcessor. Here again, check
code from the needed extensions. Tiles simply override methods doInclude() and
doForward().
Hope this help,
Cedric
