Hello -

I want to convert my old method of storing and retrieving images to 
ERAttachment.
This is the last big chunk of my conversion to Wonder.

I already have my documents modeled in the current setup:

ProjectDocument --> ProjectDocumentObject (id,blob)

Is there an easy way to make this:

ERAttachment --> ERAttachmentData ?

Can I just make ProjectDocument subclass ERDatabaseAttachment and 
ProjectDocumentObject ERAttachmentData?

I don't seem to see where I can change the object mappings. In other words do I 
have to ERAttachment and ERAttachmentData?
Or can subclassed objects "just work".

There is a lot of data here so I really don't want to write out and the 
reimport all the documents.

Thanks
James
