Hi There, we have an Array which is converted via a Binded Converter: else if (TTools.IsOfBaseClass(value.GetType(), typeof(System.Activities.Presentation.Model.ModelItemCollection))) { OurBaseClass[] test = (value as ModelItemCollection).GetCurrentValue() as OurBaseClass[]; List<OurBaseClass> list...
I am using the VS2010 RC, and trying to put a "ReceiveAndSendReply" activity into a Flowchart. When I drag the activity out of the toolbox and drop it into the Flowchart, all I wind up with in the designer is an empty Sequence activity.
