[jboss-user] [JBoss Seam] - Re: Seam 1.1 beta1&2 (dis?)injecting issue

Thanks for the prompt response. Perhaps what I'm doing is a little unusual. I've created a simple way to update resource bundle messages that is intended to be a stop-gap until java 6 sorts out ResourceBundles.

My application also has a login component that takes a username and password. But the username textbox is pre-populated with a prompt for a user name, and it gets that from the reloadable resource.

So when the loginAction is created, it needs to access/ create the reloadable resource. See the code extracts below.

I'll checkout cvs head and give it a go. Did you still want a test-case for this issue? Let me know if you need any more info.

Cheers, Pete.
