[DMN Designer] Data-types: Grid: LiteralExpression

Literal Expression

• Grid header could show Output Data Type
• Editing Output Data Type is possible via Properties panel
• Update header when Output Data Type is changed via Properties panel

Manual acceptance test

• Resizing
• Ctrl+C, Ctrl+v
• Default Data Type for literal expression
• Selecting itemDefinition
• Long name of data type
  • Column Width is not adapted automatically nor Data Type name is abbreviated, do we want to address somehow in future?
  • [manstis] We could resize the column based on the Data Type name; feel free to open a (minor) JIRA and etirelli can comment.
• Used in levels of context grid
  • 
  • Should be the data type shown anytime or just if literal expression is top level context entry?
  • [manstis] For LiteralExpression only when top-level. ContextEntry will have a similar editor when https://issues.jboss.org/browse/DROOLS-2796 is complete.
• Changing data type in graph node
• Changing data type in properties panel
• Building project
  • Should the deployment fail if I have literal expression of type number but inside string constant like: "string constant"?
  • [manstis] Validation will be performed when saved/validated and errors appear in the Message Console. How validation is supported is, IIRC, a JIRA somewhere already.
• Undo / Redo
