A change proposal was made during product demonstration to management team, in order adapt current datamodeler layout too use the navigation bar provided by uberfire.

The change involves to adapt current functionality to manage data objects one by one.
When the user cliks to a data object in the navigation bar, a new editor window will be opended to "edit" the selected data object. (see attached image)
If the user clikcs on more than one file, N edition windows will be opened.

The attached image "DataModelerChangeProposal.jpg" shows the new suggested layout for one by one edition.
