ColorEditBox Deadlock

Posted 12 years ago by Jake Pearson - Software Developer, Alion Science and Technology

Hi,
I just installed the 2011.2 build. I dropped a ColorEditBox on one of my views and ran the program. When the view is displayed, my program locks up. I put the current call stack below. I tried it in WPF Studio 2011.1 and didn't have the same issue. Please let me know if you would like additional information.

thanks,
Jake

Hi Jake,

Yeah, that is a known issue and we have a fix for the next maintenance release. Some code we had that was waiting for the System.Windows.Application.Current property to be set was looping forever. I've updated this code to prevent the infinite loop.

Regardless though, without System.Windows.Application.Current being set, our theme manager would be unable to dynamically change the current theme. If this isn't something you use, then it would not be a concern. If it is, then you would need to artifically create a dummy WPF application like so:

private static void CreateWpfApplication() {
    if (System.Windows.Application.Current == null)
        new System.Windows.Application();
}

You can then call this early on in your Program's Main method. This can also be used as a workaround for the infinite loop until the maintenance release it out.

That did the trick, thanks for the quick response!

The latest build of this product (v24.1.1) was released 2 months ago, which was after the last post in this thread.
