[DMN Designer] Add support for copy and paste in grids ------------------------------------------------------ Key: DROOLS-4800 URL: https://issues.redhat.com/browse/DROOLS-4800 Project: Drools Issue Type: Enhancement Components: DMN Editor Affects Versions: 7.30.0.Final Reporter: Michael Anstis Assignee: Guilherme Gomes Priority: Major Labels: drools-tools Add support for copying/pasting between cells in grids. The implementation should re-use and integrate with the existing Stunner mechanism (i.e. if there are toolbar buttons to copy/paste nodes they should be re-used to copy/paste cells when in the grid view. Copying a grid cell(s) should probably replace any _node_ content on the virtual clipboard and vice-versa. In addition to toolbar buttons the feature should probably be also exposed on a context-menu and keyboard short-cuts... Pasting a cell into another should only be possible where the type of cell is compatible. I.E. you cannot paste an expression cell (e.g. nested Decision Table on a ContextEntry) into a literal cell (e.g. Relation grid cell).
