Actions excecuted twice with s:button

telenko.lfeys.reference.be Apr 28, 2008 9:29 AM

Hello,

I am experiencing some weird behaviour in seam (1.2.1).

If I use an s:button my actions are executed twice, if I use a h:commandButton, they are executed only once (as expected). For some actions this is not a problem, but for others is absolutely undesirable.
The problem is that I can't use h:commandButton, because then I get errors with a custom facelets function (ClassNotFoundException when submitting. See my previous post).

Does anyone have an idea what might be causing my actions to be executed twice, or how I could check what is going on (by debugging a specific seam class perhaps)?

Thanks.

Luc

Hello,

I have been trying to dig a little deeper into this problem, but can't find out what is going wrong.
If I press for example the 'Search' button, the 'searchAction.searchByName' action is supposed to be called 'once'. But it's invoked twice. So I've checked the stacktraces on both calls and they are identical (see below).

Any suggestions on this problem are welcome.

Thanks,

Luc
