My flex viewer 2.2 application currently contains a number of Widgets that are managed by the Widget Manager.
I tried to fix the issue you solved above by loading all widgets into the same application domain as the loader:
wgtInfo.load(ApplicationDomain.currentDomain, null, null, moduleFactory);
I now get the following error whenever I attempt to load the Helper widget:
> TypeError: Error #1009: Cannot access a property or method of a null object reference.
Am I missing something? Thanks in advance.
