102150 - XUL in XHTML: <tree> in XHTML file causes crash

Status: RESOLVED INVALID

(Core :: Layout, defect)

Description

[Shawn Vincent]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.4) Gecko/20010913
BuildID:    2001091303

A tree control that works properly in a XUL source file causes Mozilla to crash
when contained within an XHTML file.

Reproducible: Always
Steps to Reproduce:
1. create a XUL file containing a tree.  load it, watch it work
2. copy the XUL file to an .xhtml file, edit the header/footer to make valid XHTML.
3. try loading this XHTML file, observe the crash.

Actual Results:  Crash

Expected Results:  I presume that XUL controls should render when embedded in
XHTML files (most controls do)

I include simple test files that reproduce the problem on my browser.

The first works as expected, the second crashes.

Working XUL case (errorcaseGood.xul):

  <box xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
       xmlns:h="http://www.w3.org/1999/xhtml">

    <tree>
      <treechildren>
	<treeitem>
	  <treerow>
	    <treecell label="I ate a half-dozen hot dogs"/>
	  </treerow>
	</treeitem>
      </treechildren>
    </tree>

  </box>

Crashing XHTML case (errorcaseBad.xhtml):

  <h:html xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
	  xmlns:h="http://www.w3.org/1999/xhtml">

    <h:head/>

    <h:body>

    <tree>
      <treechildren>
	<treeitem>
	  <treerow>
	    <treecell label="I ate a half-dozen hot dogs"/>
	  </treerow>
	</treeitem>
      </treechildren>
    </tree>

    </h:body>

  </h:html>

I don't know XUL well at all, but David does.

Testcase no longer crashes.

This bug should probably be closed.
