[jboss-user] [JBoss Seam] - Re: problem in a simple seam application

[mnrz]

Hi Petemuir,

eventually I could find the problem, it was something with starting embedded Ejb container because I am using Tomcat and it was not starting properly, I put SeamExceptionFilter and after that all exceptions have emerged in Tomcat console.  

after all, I've got a new problem, after click on button to submit the form following exception throws:

I think SeamPhaseListener diclared in faces-config.xml can not bind the RegisterAction class to action represented in jsp file.
