Components in EJB project come and go from Seam Components v

[rossj2]

Hello,

I have created a new Seam project (EAR) using the new Seam Web Project wizard. I then added several entity classes which I had created previously in another project (copy/paste/refresh) to the new EJB project (the ejbModule directory). The entity beans are annotated with @Name.

The problem is that the Seam Components view doesn't show the new components. Code completion doesn't work for them either. In both cases I can see other components (e.g. authenticator).

The strange thing is that if I edit an entity bean class file and resave it, the component appears in the Seam Components view and code completion works. I can do this for each bean. However, if I do a Project > Clean to have all projects rebuilt, I lose the components again.

Any thoughts?

/Thanks, Ross.

Which version of JBossTools do you use?
Are there any errors in Eclipse log?

[rossj2]

Okay, I should have looked at the log... (see below)

JBoss Tools: 3.0.0.GA-R200903141626-H5
Seam: 2.1.1.GA
Eclipse 3.4.2
JDK 6 update 13

The following exception appeared in the eclipse log after performing a clean of all projects.

[akazakov]

Do you have any annotation types in your sources?
Seems to be the issue which we have fixed in 3.0.1
See http://www.jboss.org/index.html?module=bb&op=viewtopic&t=153483
and https://jira.jboss.org/jira/browse/JBIDE-4144
We are going to release 3.0.1 soon but you could try 3.0.1 nightly build or use the workaround described in http://www.jboss.org/index.html?module=bb&op=viewtopic&t=153483.

[rossj2]

That's it! I have 3 @RoleCheck annotations defined for seam security. However, I have not yet begun using them. I commented them out and the problem (and exception) has gone away.

Looking at the JIRA issue it appears to be the same problem. I haven't tried the nightly build since I don't really need the annotations at the moment. I'm happy to wait for the fix to be released. If you want me to verify this against the nightly build, please let me know.

Thanks akazakov for your quick and accurate analysis. Much appreciated.

/Ross.
