Hi,
I am trying to modify Randy's flow example to an existing workflow model
I have. So far I have been able to take care of part creation for all my
model elements and I can successfully drag drop them on the main
container (MainWFContainer).
However one of the problems I am having is that all my contained model
classes refer to the base model class (MainWFContainer). In the
standalone version I passed it as an argument in the constructors and I
have these constructors in place. However I am unable to invoke these
constructors when adapting the flow example. Every time the empty
constructor is called.
If I am correct, the new model instances are get created in the
FlowElementFactory class. However every time a item is drag and dropped,
the FlowTemplateTransferDropTargetListener creates a new instance of the
FlowElementFactory.
How & where can I save a reference of the base model class and then pass
it as a parameter in the createInstance calls for all the model classes?
Thanks.

You seem to be mixing the notion of container with that of being a base
class. A base class can be created and added within the factory. A
container class reference can be added when the class is dropped into
the container.

Sorry if I sounded too confusing. You are right, I indeed meant container
reference to be passed in the constructor. Today morning on my way to school
I too thought that I should try out adding the container reference in the
addChild method of the container class. Will try it out today.
Thanks CL
