If you enter a document and/or link in the 'Dictionary' it shows in the 'Attributes' (right pane), however, if you add a document and/or link from the 'Attributes' it does not show when you click the 'Dictionary' of the Object or Task, why?
It appears to be bidirectional only from the Dictionary and not from the Attributes. Is this intended behavior or a bug?
This is intended as the Dictionary is used for creating / defining custom attributes to be reused. When document attributes are defined incidentally per diagram, they cannot be reused nor will they appear in the dictionary.
