>                 Key: JBIDE-2052
>                 URL: http://jira.jboss.com/jira/browse/JBIDE-2052
>             Project: Tools (JBoss Tools)
>          Issue Type: Bug
>          Components: Seam
>    Affects Versions: 2.0.1
>            Reporter: Luke Maurer
>
> If a Seam component has an @Install annotation without the "precedence" attribute, then when saving the component, a NullPointerException appears in the log and the Components view remains incomplete. Adding precedence=APPLICATION to the annotation fixes the problem (and serves as a workaround).
