Hi -
The code below attempts to create an association between two utility network features within a HandleEditCompletedEvent. As it is, it consistently throws an error when attempting to add the association, line:
_un.AddAssociation(assoc)
The error message states that "This task must be performed within an Edit Operation" - but the AddAssociation *is* performed within an edit operation.
Now, it may be that what I'm trying to do -- perform an edit to create an association within an edit event fired on creation of a feature that would be part of that association -- is just not supported. But that's not what the error says.
Anyway, any guidance on this would be much appreciated.
Thx,
Ed
