Thanks for your response,

I think, even with an ajax approach, concurrent requests for same action
would result in unexpected output as these actions are stored by same action
name at background. So in fact this is not a presentation constraint but a
processing constraint. We can neither prevent concurrent submits nor make
them wait for another to finish. They need to work parallelly. So i think
what we need here is a way to store background threads separately possibly
on per-request basis instead of per-session basis?

Thanks.

So, how to override this ExecAndWiatInterceptor behaviour? Is it possible to
map by some key other than action name?

If we use wildcards while defining action mapping, can we bypass this
constraint? This way we can call myAction1, myAction2 and myActionRandomN
which trigger myAction.action. Does ExecAndWaitInterceptor store and return
these separately?

Thanks.

The constraint here is about ExecAndWaitInterceptor storing and returning
multiple copies of one certain action. This constraint is already in the
documentation. We are looking for a turn around.

For example if we open 2 browsers (which share the same session) and call
same action (which has ExecAndWaitInterceptor) with different parameters,
there may be no certain result that which browser will show which request.
Thanks

I don't think that it can be done with an ajax approach. With ajax or not,
concurrent requests for the same action name returns first action's result.

I tried this simple scenario with an action which outputs its query
parameter. I also added a thread.sleep in execute method to gain extra time
to call the same action more than once.

When i triggered the same action with different parameters in 2 separate
browsers, first one redirected to the wait page as expected. At that point i
triggered the second copy. When they both returned from wait page, both
output were first action's parameter.

I think ajax/div approach would show the same behaviour with the above.

However, the wildcard action mapping seems to separate the wait and returns.
when i mapped the action name like myaction* and called myaction1 and
myaction2 at the same time like before, they seem to return with their
respective results. i guess, this can also be used to separate the key.

Thanks for responses.

Thanks a lot for that answer, but how do I get old posts ?

Anyway, with that piece of information I have new stuff to search for,

Also wanted to add, that my action gets properly called (execute()). but my debugger shows me none of the setter methods is ever called, which results than in a NPE on the userService.
