[jboss-user] [JBoss Tools (users)] - Re: Facelets code completion

[kpolice]

I am having code completion problems again.
When I create a new project everything works fine but after some time I lose code completion on standard JSF tags: h: and f: but it works perfectly fine with rich: and a4j: .

The error I see in the log is:
null

Also in the tags that code completion works I get duplicated options, e.g.:

id
name
rendered
id
name
rendered

instead of 
id
name
rendered
