[baseten-users] Assertion Failure

[Thomas Hart]

The tutorial says to install the two frameworks. I was able to do  
that. Then I'm supposed to add the BaseTen.ibplugin. When I do that  
Interface Builder displays this message in its details:

"Assertion Message: Two plug-ins  
(fi.karppinen.BaseTen.InterfaceBuilderPlugin and  
fi.karppinen.BaseTen.InterfaceBuilderPlugin) both integrate a class  
description for the class BXDatabaseContext. The primary definition  
for the class should only come from one plug-in; the other plug-in  
should be declaring a category. Declaring a category is accomplished  
by omitting the super class from classdescription file.

Any suggestions?

Again thanks for the help.
