[GemStone-Smalltalk] Namespaces in VW

[Annick Fron via GemStone-Smalltalk]

Hi Richard,

	In fact I have done all sorts of things, like setting
generateServerClasses: true
and defining connectors for all classes with postConnectAction: #updateGS.
I think my database classes are inconsistent, in particular I have the same classes in UserGlobals and UserClasses, and I don’t know which is which.

I also had a clash in MessageSend, and ReadWriteStream, and I had to rework my data model not to use those classes.

	Is there a way to reset all user classes or even all the database ?
	I have more or less succeeded in storing my object in the database now, and wanted to retrieve it.

	From a clean database, what would be the safest to do, define connectors or generating classes by program ?
	Best regards


	Annick
