I have my MDG extension which consists of custom diagram and custom element. If I drag standard Class element onto my diagram as a Property, there will be new element type of Property.
How to change this behavior ? I need to change, the type and stereotype on the fly when dragging a class on a diagram. The _instanceMode, _instanceOwner , _instanceType aren't applicable for standard Classes , only for MDG extension.
In order to create an instance you need to define it in your profile as extension to Object and/or Property (depending on what you need). This profile element can be dragged from either a self-defined toolbox (preferrably connected to a diagram) or from the Profiles in the Resources window (if you don't have a full-fledged MDG and use the Resources to import your profile). Once you have created it you can link it via Ctrl-L to a classifier of your choice.
