Potential NullPointerException in VPE openned on file from project without JBossTools nature
--------------------------------------------------------------------------------------------

                 Key: JBIDE-5542
                 URL: https://jira.jboss.org/jira/browse/JBIDE-5542
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: Visual Page Editor core
    Affects Versions: 3.1.0.CR2
            Reporter: Denis Golovin
             Fix For: 3.1.0.CR1


I cannot provide exact steps to reproduce it but stack trace tells me that that might happen for any none JBossTools project. For me it happens on project with JSF capabilities. To fix this problem on JBossTools JSF project, it should be closed/opened and VPE starts working.
