Many clicks on buttons - Conversation

clemente.cioffi Feb 26, 2008 6:15 PM

Hi,
I'm using Jboss 4.0.5 GA, Seam 1.2 and Icefaces 1.6.0

In my application I noticed a problem when I click many times
on menu links or buttons linked to server-side methods that execute business operations(ex: retrieving data from DB..).
My application is based on using conversation.I have a menu where each voice(section) stops the current conversation and begins a new one.So I use the same conversation inside the same section.
The error(HTTP Status 500 -) I got when I quickly click on menu or buttons is the following:

Is there anyone can help me???It's a big problem for me, because the application is not stable.

Thank you very much

I guess you have tried your luck at the ICEFaces Seam Integration forum?

Increase the concurrent-request-timeout to, let's say, 10000, in components.xml.

If thathelps, it is a known issue.

<core:manager concurrent-request-timeout="10000" conversation-timeout="120000" conversation-id-parameter="cid"/>

Hi thanks for the replies.
For Nicklas, I didn't try 1.7 beta beacuse my application is in production environment and I need a stable icefaces version.Do you think this problem resolved in that version??
For Daniel, I increased that parameter also more then 10000 but the problem remains.
Thanks

Please try the 1.7.0.Beta1 release of ICEfaces first. If the problem persists, then post your xhtml page, web.xml and backing bean (or the basic part of them to the ICEfaces forum

You could be using partial submit (is synchronous true or false in your web.xml?) and with asynch you may have a new thread(new conversation) spinning off before the old one is terminated (on same veiw root). Work was done on this for 1.7.0.Beta1 release.
