BUG: GUI allows an attribute to be "renamed" with a name already is use (!1514) · Merge requests · CMB / SMTK · GitLab

Robert M. O'Bara requested to merge bob.obara/smtk:addAttributeRenameWarning into master Apr 02, 2019

the attribute system does prevent the rename but the user is not notified the renaming did not occur. Also the GUI does show the attribute with the new name until the view is refreshed
this commit now presents a warning message and reverts the name displayed to the original value.
