Struts w/Ajax with Struts again

[cpanon <cp...@yahoo.com>]

Hello 
I am able to use an Ajax call to a struts action and with getInputForward() get the get the data back.  (With prototpye and json, very, very elegant).  I am now realizing that I have cases where I want to reprocess all components, i.e. I want the actionForm to be updated and the jsp recalculated, I want the session objects to be reprocessed so my iterate tags will show the updates, etc.  I understand how with getInputForward it doesnt happen.  If I setAttribute(), the original value that was processed when the form first generated is all that ever shows.  A simple findForward() does not force the reprocessing,ie still the original values of the actionsForm members.  Is there a way to force a complete reprocessing the jsp from within an action?  tia.

ajax's responsibility is to return either json or html formatted text to innerHtml attribute of div tag identified in ajax call

 

other activity such as refreshing session attributes would need to take place

in the action class..upon return from action all tags of the jsp would re-display the content based on the refreshed state for those session attributes

 

another strategy is to create and/or modify a jsp in the action and on return forwards to a result *which will forward to the just created or modified jsp* 


you're welcome

The form will not be updated unless you refresh the values or the part
of the page that displays the values you want to be updated. So you
would have to "manually" do this processing some returned updated
values in a json result, or by returning the result of a "partial" jsp
which re-renders the part of the page that you want to be updated, and
then replace the existing html (using innerHTML).
