[TYPO3-english] Workspace Module from 4.5 in IE6 -> expanding row throws JS error

[Andreas Kiessling]

Hi,

i am moving a site from 4.4 to 4.5 and i struggle with the backend 
module in IE6
After expanding i just get an error that
"undefined" ist Null oder kein Objekt
I think that IE6 somehow does not create the div where to display the 
data (remData[xyz]), but could not track the problem further than the 
call to
Ext.ux.TYPO3.Workspace.RowPanel.superclass.constructor.call(this, config);
in the Ext.ux.TYPO3.Workspace.RowPanel

Can someone confirm that error? IE8, Chrome, Firefox are working just 
fine, but unfortunately IE6 is required for that project...

Regards,
Andres
