Opening a window instance from a menu works only 2 times on chrome or iExploerer
Hi am using a docked menu where some items open custom classes that are simply an extension of a window (see below an excerpt of the code, EXTjs 4.0.2).
Everything goes well on Firefox 4.0.
Using Chrome (12.0.742.100) and i Explorer (6.0) on the third time I open one of these windows clicking on the menu item, errors like following ones appear: Uncaught TypeError: Cannot read property 'isReader' of undefined
Uncaught TypeError: Cannot call method 'substring' of undefine
and i should reload the page to have it working. I have done a lot of debugging, but without luck.
