[JBoss Seam] - entityManager goes null on form submit?
by wesleyhales
have no idea what's going on here:
I am using a custom servlet filter that renders my xhtml to pdf. After the PDF is created I can hit the back button and refresh the page (or go to another page) and still view data from the database on the other seam pages.
But, when I submit a search or any form in my app I get the following stack trace with entityManager null...

Like I said, I am viewing new data from the database upon visiting different pages in my nav (after getting the stack trace and visiting the good ol' debug page), the entityManager only comes up null when I submit a form.
Any ideas? Thanks! PS: I just checked out the latest from CVS and am still getting the same thing.

Hi henrik,
I have been doing this by passing a parameter when the nested conversation is started. The backing bean (SFSB in the nested conv. context ) grabs the parameter and keeps it in a String var for later use.
I am hard coding the outcomes,
If you find a better way, please lmk.
