Subject [jira] [Created] (CB-8758) WP8: splashscreen.hide() causes exception to be thrown
Date Thu, 26 Mar 2015 17:38:53 GMT
Dan Polivy created CB-8758:

             Summary: WP8: splashscreen.hide() causes exception to be thrown
                 Key: CB-8758
             Project: Apache Cordova
          Issue Type: Bug
          Components: Plugin SplashScreen, WP8
            Reporter: Dan Polivy
            Assignee: Jesse MacFadyen

When calling the hide() method on splashscreen, on WP8, the call to Popup.IsOpen throws a
TargetInvocationException due to invalid cross-thread access.

I don't know the specifics, but most likely the threading model for how plugins are executed
has changed over time, exposing this exception.

+		[System.Reflection.TargetInvocationException]	{System.Reflection.TargetInvocationException:
Exception has been thrown by the target of an invocation. ---> System.UnauthorizedAccessException:
Invalid cross-thread access.
