[jbosstools-issues] [JBoss JIRA] Resolved: (JBIDE-3144) EL resolution causes VPE to loose its synchronization

[Maxim Areshkau (JIRA)]

Maxim Areshkau resolved JBIDE-3144.
-----------------------------------

    Resolution: Done


EL processing was changed from using cloning nodes to using proxy. Now junit tests for content checking don't take into account el using and resolution, so to check it was created JBIDE-3228.

> 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 ;(
