Status: RESOLVED WORKSFORME

[Mark Robson]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

A combination of a RDF datasourced'd listbox removeElementAt and
builder.refresh() crashes Mozilla.

Specifically, if you have a listbox with headings coming from a RDF datasource,
remove an element with removeElementAt() (which doesn't work properly anyway),
then refresh, remove etc, it will crash Mozilla.

This is related to two other bugs - builder.refresh() not working and
removeElementAt() removing things other than what it's supposed to (

Reproducible: Always

Steps to Reproduce:
1. Create a RDF-datasourced listbox
2. Using scripting, remove elements, refresh the builder, refresh the builder
again and remove another element


Actual Results:  
Mozilla crashes

Expected Results:  
The item should have been removed and then the builder should put it back when
refreshing from the RDF datasource.

Zip file containing test case will be attached shortly.

Attachment: Test case

UL test case.

Comment 2

[Mark Robson]

see also: 

277498 listbox removeItemAt also removes column headings.

and
241827 builder.refresh method sometimes leaves blank values when datasource is
changed.	

In description, references to removeElementAt should be removeItemAt (My mistake)

Yeah, I see crashes in a build from April, but not from June or later...
