Hi!Well, you are calling addObjectToBothSidesOfRelationshipWithKey ( aValue, "person" ) inside the setPerson method. Assuming the addObjectToBothSidesOfRelationshipWithKey will set the person using key/value accessors, addObjectToBothSidesOfRelationshipWithKey will call setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson that will call addObjectToBothSidesOfRelationshipWithKey that will set the person using key/value accessors by calling setPerson ...
Get the ideia? ;) Yours Miguel Arroz On 2007/12/04, at 23:09, Owen McKerrow wrote:
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 ).
