Description David Sciamma CLA 2005-08-08 05:17:38 EDT 
When you create a new emtpy file sitemap.xmap and when you open it with the
Lepido editor. It throws an exception :
org.eclipse.jface.util.Assert$AssertionFailedException: null argument;
    at org.eclipse.jface.util.Assert.isNotNull(Assert.java:149)
    at org.eclipse.jface.util.Assert.isNotNull(Assert.java:125)

org.eclipse.jface.viewers.StructuredViewer.getRawChildren(StructuredViewer.java:849)

This bug was reported by Ross Gardler. It is a known bug and a fix is being
developed.
Comment 1 David Sciamma CLA 2005-08-08 05:38:14 EDT 
A nice solution for this bug could be an extension point to provide templates to
initialize empty files.
Those templates could also be used in a generic wizard to create files for all
the visual editors.
Comment 2 Ross Gardler CLA 2005-08-09 15:22:44 EDT 
I added a hard coded template to the newForm wizard to workaround this problem.
However, the extension point you refer to sounds interesting. Do you have a
pointer to more info on that Eclipse feature?
