We have been running automated tests that execute successfully on IE8, FireFox 3.6 / 5, and Chrome (latest version). The code uses lines of code such as:
//where true indicates whether to invoke the OnChange event
This logic works absolutely correctly with respect to eliciting the correct application behavior in the other browsers mentioned above, but not in IE9 (although I can find no mention in documentation or forums that there are any known issues similar to this).
We generally run with the latest released version of WebAii 2011.1.712, but I have also tested this with the latest internal build 2011.2.1007 and there is no improvement in the behavior for this functionality.
Please advise as to whether any known resolutions or work-arounds are available for this, since we are shifting focus towards IE9, and the issue is quite debilitating to our current regression suite.
