I have two RCP applications accessing a model instance on a CDO server.
Updates flow in real-time both ways as each user saves his/her model and
the UI is dynamically updated. Pretty cool.
In one scenario a series of integer values are updated on one side (lane
numbers) and when delta notifications are sent to the other user, I get
the stack trace pasted below.
Never had this error before I migrated from base EMF to CDO and tried
this multi-user access to the model.
Here's the snippet from NotificationImpl.java where the error occurs:
public int getNewIntValue()
{
if (primitiveType != PRIMITIVE_TYPE_INT) throw new
IllegalStateException();
return (int)newSimplePrimitiveValue;
}
The debugger shows that the value of 'primitiveType' is -1, rather than
the expected value of 5 (PRIMITIVE_TYPE_INT).
Here's the stack trace:
