dijit.form.Textarea tries to access window.frameElement properties even when it is null

[guest]

There is a script in dijit.form.Textarea which attempts to grab the window.frameElement.postCreate function and execute it. It however does not work when window.frameElement does not have any properties or is null.

I am not sure if this is a Textarea bug specifically that causes frameElement to be null, but it only happens after I destroy a previous Textarea, and possibly after I destroy a dijit.Tree (not completely sure whether it is relevant though. The first creation of a Textarea is fine, it just falls over when I try to create one later in the applications life.

I made a simple patch to do a sanity check on window.frameElement so that it does not fail, as there is already a lower level check so it seems to be an optional action.

Attaching a patch against dijit trunk svn as at revision 11169.

Would feel a lot better with a testcase for this (attached using the "attach file" button)

On FF2 mac (and probably windows) this causes a syntax error on load of themeTester.html or test_textarea.html.
