EL resolution causes VPE to loose its synchronization
-----------------------------------------------------

                 Key: JBIDE-3144
                 URL: https://jira.jboss.org/jira/browse/JBIDE-3144
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: Visual Page Editor core
    Affects Versions: 3.0.0.beta1
            Reporter: Max Rydahl Andersen
            Priority: Blocker
             Fix For: 3.0.0.cr1


(I've only tried this with the Seam generated projects, but I don't think it is specific to it)

EXECUTE: Create a Seam web project
EXECUTE: Change template="layout/template.xhtml" to template="#{request.contextPath}/layout/template.xhtml">
EXECUTE: Setup request.contextPath = ./ in page design options
EXECUTE: Refresh editor
ASSERT: Editing continues to work
ACTUAL: Edits is not visible in VPE and edits through VPE result in edits in the top line of the file instead of inside the file.

This is marked blocker since EL resolution is rather pointless if it breaks up the editor ;(

Sometime I got this exception:
