User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050531 Firefox/1.0+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050531 Deer Park Alpha 1

The following short xul example works fine with Firefox 1.0.4 and not with Deer
Park Alpha 1. When you push on the OK button, the title value of the selected
item should appear in an alert window. With Deer Park, an exception occurs (see
actual results for exception details).

<window id="winTree" title="Tree example" orient="vertical"
  xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
  <script type='application/x-javascript'>
    function cgValidSelect(aTreeId, aColId) {
	var lTree = document.getElementById(aTreeId);
		
	//Get selected item
	var lCurLig = lTree.currentIndex;
		
	if(lCurLig >= 0) {
	   // Get content of the selected item
	   var lCurText = lTree.view.getCellText(lCurLig,aColId);
	   alert(lCurText);
	}
	else {
	   alert("Choose an item, please.");
	   return false;
	}
	return true;
    }
  </script>

      </treechildren>
    </tree>
    <separator orient="horizontal" />
    <button id="btnValidSel" label="OK" default="true"
      oncommand="cgValidSelect('treeTest','colTest_title')" />
  </groupbox>
</window>



Reproducible: Always

Steps to Reproduce:
1. Save the test example in a .xul file
2. Load the .xul file with Deer Park
3. Push on the OK button

Actual Results:  
An exception occurs generating the following message in the JavaScript Console :
Error: uncaught exception: [Exception... "Could not convert JavaScript argument
arg 1 [nsITreeView.getCellText]"  nsresult: "0x80570009
(NS_ERROR_XPC_BAD_CONVERT_JS)"  location: "JS frame :: file://tmp/tst.xul ::
cgValidSelect :: line 20"  data: no]

Expected Results:  
The "title" value of the selected item should appear in an alert window.
