This happens in prime and also in newly configured apps, but surprisingly not in TLDemo:

Command 'dispatchControlCommand' failed.

Analysis

The context menu’s title contains the object for which the context menu is displayed. However, the lookup for the `tl:LabelProvider` fails because it cannot be determined in which table the new grid object is stored (since a LabelProvider fallback can be defined for all types within a table).

Test

• Create a new app.
• Define a new Type A.
• Create a grid view for A.
• Add a "Create Grid" button for A to the view.
• Use the new button to add a new row to the grid, but do not commit or save it.
• Open the context menu over the transient row.
• Expected behavior: The context menu opens and has a title.
