All,
I have the component that I want displayed in the palette defined in an
XML somewhere. I want to utilize CombinedTemplateCreationEntry to create
instances of the object and act as Drag sources. However, he is the
catch, each Component tag that I have in the XML file contains additional
information such as the icon to use, the Figure class to instanciate, the
initial dimensions of the figure object in the edit part viewer, and the
model object class. So I have parsed this information into XMLObject types
The question is in the CombinedTemplateCreationEntry, it asks for a
template object and a creation factory (which is suppose to instantiate
the model object). In all the examples I have seen, the template object
and the object passed into the creation factory is the same (I.e the model
object). However, what shall I do in my case? Do I set the template
object to be the XMLObject and then pass in XMLObject.ModelObject.class to
the creation factory?
Thank you in advance.

It should have been "can be used by the CreationFactory in whatever
way you like", not "cannot ...". Sorry.

Thank you for your response.
So what you are saying is since I have already all the information I need
in my XMLObject, for the time being, just pass in any dummy/unique ID to
the CreationFactory and then actually instantiate the object myself in the
Command?
As for the other attributes I need for the Edit Part viewer, just use them
directly from the XMLObject as needed.
