Passiert in prime und auch in neu konfigurierten apps, erstaunlicherweise aber nicht in TLDemo:

Command 'dispatchControlCommand' failed.

Analyse

Das Kontext-Menü enthält in seinem Titel das Objekt, für das das Kontext-Menü angezeigt wird. Das Lookup des tl:LabelProvider scheitert aber daran, dass für das neue Grid-Objekt nicht ausgerechnet werden kann, in welcher Tabelle es gespeichert wird (da auch für alle Typen einer Tabelle ein LabelProvider-Fallback festgelegt sein kann).

Test

• Neue App anlegen.
• Neuen Typ A definieren.
• Grid-Sicht für A erstellen.
• Grid-Create-Button für A in der Sicht hinzufügen.
• Über neuen Button neue Zeile in der Grid hinzufügen, aber nicht übernehmen oder speichern.
• Kontext-Menü über der transienten Zeile öffnen.
• Erwartung: Das Kontext-Menü öffnet sich und hat einen Titel.
