I am trying to create a drawing by using "insert new drawing" When I hit save it throws an error saying I don't have necessary privilege's, but when I share the drawing using "share this representation".. it will allow the save. Why might this be?  It should be noted... that this is a Product that was shared with me by another organization.  Is it possible that me adding a child (non shared) makes an ownership issue?  I am able to write to the collaborative space if I share first.
