I have been struggling with this as well for the last few hours. The way I finally solved it was giving the injected variable the same name as the @Name value of the object to be injected. If I do not do this, I see in the debug that Seam tries to find a contectVariable with the name of the variable to be injected. It does not look (anymore?) for a contextVariable of the same type. If it finds nothing, no the create=true does not go off.

So:

@In(create=true) MyObj myVar
in combination with
@Name("myVar")

@In(create=true) MyObj myOtherVar
in combination with
@Name("myVar")

@In(create=true, value="myVar") MyObj myOtherVar
in combination with
@Name("myVar")

Seam has *always* done bijection by variable name.

yeah... this is different to my problem. I had the injected variable name matching @Name, and it still couldn't handle auto-creation from within the richfaces tab panel.

Incidentally I never solved this. Just worked around it by refactoring a bit, so I didn't have to call any components referencing any injected auto-created components from the tabpanel.

I think this due to a richfaces tabPanel behavior change/bug.
See http://jira.jboss.com/jira/browse/RF-1047 and referenced forum post.

I'll bet your EntityController is conversation-scoped, right? The conversation scope isn't available during restore view (when restoreState() is being called above), so that's why it's bombing.

Your issue is not quite the same one I had, but it's related. You might comment on the issue, asking if they can possibly refrain from calling getValue() during restoreView. If they can't, though, you'd probably have to mark your injected entityController as non-required. (That is, if you decided to undo your workaround-refactoring, which I'm not necessarily recommending; I'm saying this more for anyone else who might be having the same problem.)

@Pete, Yes, I know, but if I do not have a user as a variable and have an @In(create=true) I would have expected seam to create one.. otoh, how would I access it then....under what name.....hmmmmm I Probably always did this correctly by accident. Sorry for disturbing this thread ;-)

matt - you are spot on - i was trying to reference a conversation scoped bean from a session scoped bean, from the tab panel, and it was this part that was failing.

thankyou very much for the explanation! it looks like it's been fixed in richfaces 3.2.0, so maybe i'll try upgrading...

Sorry, but I am a bit confused as to the @Name, and variable name solutions proposed.

I have a UserServiceAction (SFSB), and a User (EB).

You need a factory for user or to make User a Seam component.
