51034 - getElementsByTagName() causes exception

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect, P3)

Description

[Christian Riege]

when calling getElementsByTagName('*') on an element that was obtained via a
getElementById('myId') element, the following exception is generated:

JavaScript error:
 line 0: uncaught exception: [Exception... "Component does not have requested
interface"  code: "-2147467262" nsresult: "0x80004002 (NS_NOINTERFACE)"

this works in M17, broken in M18 nightly build (Build ID 2000083111)

Attachment: testcase, works in M17, doesn't work in M18 nightly

[e-mail] , I don't see a getElementsByTagname("*") call in your code. 
The method is called with a "span" argument in your testcase.

I *do* see the exception (which should not occur), but you may want to update 
your bug description. Confirming on WinNT, buildID:20000-90608.

Yeah, sorry for the 'buggy' entry. I had it with a getElementsById('*') call in
my first test cases, thought it was buggy with '*', changed it to 'span' and
when it still didn't work I just put up the attachement w/o "fixing" it again.

I've narrowed this down now though:

- calling 'getElementsByTagName('*')' on the 'document' object yields the
correct results (an HTMLCollection is returned)
- calling 'getElementsByTagName('*')' on an 'Element' level throws the
exception.

it doesn't matter wether you specify '*' for "all tags" or hand the function a
specific tag to look for.
