I have an Ajax TabContainer. I also have a simple javascript function that normally can update a textbox using 'document.getElementById'
This works as expected when the textbox is outside the TabPanel but when I move the exact same textbox inside a TabPanel the Javascript function does not seem to be able to reference it.
The error reported is 'document.getElementById[..] is null or is not an object'
Any ideas

When loading I get Javascript error 'exception thrown but not caught'
The map is however loaded but only parially visible. When I doubleclick it it expands to fill the TabPanel.
When I rightclick the map the Javascript error says 'document.getElementById('..') is null or not an object'
(If I change Text1 to the textbox Text2 it works OK)
Hope this makes the problem clearer.

hmmm ... may be the id of the textbox ('Text1') is replaced with something else when the page is loaded into the browser? have a look at the source-code when the page is loaded in IE ... and try to find the textbox ... and find out its id.
