    Persist not called (after fixing validation errors)

    mjelen

      Hi,


      I have a problem in a relatively simple Seam w/ RichFaces application using entity home objects and CRUD pages with s:validateAll and s:decorate tags (no AJAX partial submits). When I submit a form with invalid (e.g. missing) data, validation error messages are correctly displayed. But when I fix the mistakes and try to re-submit the form, the action method never gets called!


      I know that it otherwise works fine, because when I submit the form without any wrong data in the first place, the action (the persist method on the entity home object) gets called just fine and the data is stored into the database.


      Seam 2.0.2GA, JBoss 4.2.3GA


      Thanks for any help, I'm slowly going crazy about this. I hope the description is understandable as it is but I can provide more information if needed (I feel like it may be a beginner's error so maybe someone will know right away what I'm doing wrong).

          Is it possible to post the xhtml for an offending page.

            It may help but you could put a controller bean into the mix.


            It can be stateless and just called the xxxx.persist.


            I must admit I have never called an entity from the view; no matter how trivial.

              It may help but you could put a controller bean into the mix.

              Oh, sorry if that wasn't clear, I am using a controller class that inherits from Seam's EntityHome. It doesn't seem to be a problem there, however, because I got the same results when I created a simple session bean and used it as the target for the button's action.


              I tried tracing the problem within RichFaces, it looks like no button pressed event is broadcast in the Invoke Application phase (but only when a postback happens due to validation errors prior to this submission).


              Here's the code of a page where it happens:

                Never mind.... the solution in my case was to change the conversation propagation settings (to join, which is what I use in other places in the application). Now I'm sufficiently new to Seam to say that I don't know why the difference, but the important thing is that it works :).
