Can't seem to figure out why the List of Tags has an out of bounds exception when trying to add a tag to the video in Edit. I thought ilist automatically created a new position for an item when needed... The Tags are supposed to be associated with a given video; so, it should generate a new tag and be associated with the video. however, I have messed with it a bit such as using Session.merge instead of Session.save and that generates a new video not a new tag... but leaving the tags[i].tagdescription as is generates the outofbounds exception. I'm sure the answer is obvious but it eludes me.
