NullPointer Exception opening view.xhtml.ftl from JDBS
------------------------------------------------------

                 Key: JBIDE-2061
                 URL: http://jira.jboss.com/jira/browse/JBIDE-2061
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: FreeMarker
         Environment: RHDS version 1.0, with Seam 2.0.1GA, on Windows XP, JBossAS 4.2.2.GA
            Reporter: Bruce Link


Used JBDS to look at the view.xhtml.ftl file under jbdevstudio\jboss-eap\seam\seam-gen\view. The FreeMarker site indicates that JBDS has a plugin for eclipse that can do this, so I figured I would see if it worked using file>open, as I could not see a FreeMarker view.

JBDS could not open the file and gave an error message, referencing a log entry. 

The edit window shows a blue horizontal line and the word ERROR.  The tab at the bottom reads "Source"  The tab at the top has an icon showing a page with the overlay <FM> and reads "view.xhtml.ftl

Same thing with other ftl files I tried to open, in the same directory or in the Seam 2.0.1GA\seam-gen\view directory.

The log entry follows:


!ENTRY org.eclipse.ui.workbench 4 2 2008-04-13 17:17:44.690
