closedView=>XML View broken

Description
Trying the View=>XML View menu gives an NPE. Seems to be broken in Vergil, as far back as 61608:
java.lang.NullPointerException

To replicate this.
1) Start kepler with "ant run"
2) Do View -> XML View
I fixed this.
Line 281 of ptolemy.actor.gui.TextEditorTableau was:
textEffigy.identifier.setExpression(url.toExternalForm());
I introduced this line with this change:
r61023 | cxh | 2011-05-23 20:24:39 -0700 (Mon, 23 May 2011) | 4 linesSet the identifier so that if we start vergil and
do File -> New -> Text Editor, type some text, Save
then the title changes from Unnames to the name of the file.I changed this to
if (url != null) {
textEffigy.identifier.setExpression(url.toExternalForm());
}
The bug no longer occurs for me within Kepler with the Ptolemy head.
