Hi All,
As part of preparing to move to Eclipse we are going back and
updating our projects so they are using packages ( this is the bit
where I run and hide in shame as I have to admit we never used them
before ) and EOGenerator if they weren't already. Anyways.....
We're having some issues, lots of issues so I think we've done
something dumb. The first issue is that
addbjectToBothSidesOfRelationship is now causing a StackOverflow
error as it keeps calling itself. In the example below its for the
AuditLog class. First up is the old code, then the new code ( thanks
to EOGenerator ) and then the error message (I haven't included all
of the stack trace as its the same thing over and over again ).
So as a newbie to packages I can't see any rules that we're breaking
( although we probably are ). Any advise/suggestions/fixes would be
most appreciated.
