Chuck your brilliant,I apologize for not picking up on this sooner, I have
stepped away from this project for at least a few months, so now I am coming
back to it and ... learning as I go again...Chuck is absolutely right it has to
do with my method of inserting the tags... below is an excerpt for how I deal
with the tag, if it's a net new tag or if it's an existing tag... if it is a
brand new tag it uses the addObjectToBothSidesOfRelationshipWithKey and as
Chuck predicts that works fine, however if it's an existing tag no such luck...
until the app is stopped and started... I came up with this hair brain scheme
to avoid having multiple entrees of the same tag in the tag table... using
addObjectToBothSidesOfRelationshipWithKey adds the tag whether or not it's
already in the table.. any better ideas about how to over come this? Thanks
again. (It's a many to many relationship that I let webobjects magic build the
intermediary table for... tagmaps) // if we find a positive result for
our search if(result.count() > 0) { // grab that existing tag
and add it to BlogEntrys tagss relationship for newEntry Tags
existingTag = new Tags(); existingTag =
(Tags)result.objectAtIndex(0);
newEntry.addObjectToPropertyWithKey(existingTag, "tagss"); }
else { //if there is no positive result, add new Tag
normally EOEnterpriseObject newTag =
EOUtilities.createAndInsertInstance(ec, "Tags");
newTag.takeValueForKey(tempString, "desc");
newEntry.addObjectToBothSidesOfRelationshipWithKey(newTag, "tagss");
