Master document handling issues on different OSes

A new phenomenon has been discovered as we were testing TT on different OSes, just to try and see whether TT is stable. Here is the summary:

Test run on:
WinXP Home..... OK
Ubuntu 7.04..... OK
WinXP Pro........ NOT WORKING
Mac Os X........ NOT WORKING

The error returned was it can't find a toolbar with the given id, which I placed clearly on top of the status bar. I seems strange that the same codes won't work on different OSes.

After further research and scouring into one of my firefox extension (DownBar), which I'm trying to replicate, I realized that we need to specify the parent node of a an XUL element we are trying to access, as explicitly as possible. Consider my previous codes:

<overlay>
....
<toolbox align="end" insertbefore="status-bar" hidden="true">
<toolbar id="tlbid">
<!--content will be added dynamically-->
</toolbar>
</toolbox>
....
</overlay>

and I was trying to get the <toolbar> element by using document.getElementById('tlbid'). Apparently this works only on WinXP Home and Ubuntu. To overcome this bug, we need to specify the parent of <toolbar> which is actually <window>. so the correct codes will be:

<overlay>
....
<window id="main-window">
<toolbox align="end" insertbefore="status-bar" hidden="true">
<toolbar id="tlbid">
<!--content will be added dynamically-->
</toolbar>
</toolbox>
</window>
....
</overlay>

The piece of code above explicitly told the browser that the toolbar with id 'tlbid' is a child node for the main window for firefox browser. I guess this helps the DOM manager to find the element required, effectively.
