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

Command 'dispatchControlCommand' failed.

Analysis

The context menu contains in its title the object for which the context menu is displayed. The lookup of the tl:LabelProvider fails, however, because for the new grid object it cannot be calculated in which table it is stored (since a LabelProvider fallback can also be specified for all types of a table).

Test

• Create a new app.
• Define new type A.
• Create grid view for A.
• Add grid create button for A in the view.
• Add new row in grid via new button, but do not apply or save.
• Open context menu above the transient row.
• Expectation: The context menu opens and has a title.
