Seam + JSF, problem with double-click

sherkan777 Oct 19, 2006 2:30 AM

HI!
I have problem with Seam/JSF?
When I click twice(versy fast) on commandLink or button submit, application falls down.

Framework dont knot what to do and gives me error:
"8:19:31,203 ERROR [SeamExceptionFilter] uncaught exception handled by Seam
javax.servlet.ServletException: /userQuery.xhtml @30,63 rendered="#{userAction.actionFlag}": pl.fargo.expert.business.UserConsole$$EnhancerByCGLIB$$dd4b45ef"

How can I protect My page or catch those exception?
When I click on link once or twice but not so fast it works fine!
I thought about protect submit by JS, but is any other way to resolve this problem?

Use Seam 1.1 (currently available only in CVS).

How do you protect against double clicks in Seam 1.1? We are experiencing this in our testing and this would be enough of a reason to move to using Seam 1.1.

Forgive me if this is in the documenation. I have not keep up to date with Seam development as we are trying to get our first release out the door and settled on Seam 1.0. However, depending on what happens in Seam HEAD, I might be willing to give it a try (looking around tonight, there looks to be a lot of new things in Seam 1.1 that I am looking forward to trying out).

Thanks,
Chris....

I serialize concurrent requests in the same conversation scope. Seam 1.1 is designed to support a high level of concurrency in a session, like you get with AJAX clients.

I'm currently using Seam 1.1. Could U show me an example code, how to protect application from users double-click?

It's very hard to me, to resolve this problem...

Are you sure? You are using a build from CVS? Seam 1.1 was not yet officially released.

1.1 != 1.0.1

No, because you havn't shown any of the code that fails, nor even a stack trace. Please don't post here without taking the time to include enough information about your problem.

sorry, i have 1.0.1:P

But I still can't resolve my problem. I think best idea is to use Synchronizer Token Pattern, on java side.
