definedFormActions

Defines the logic of form actions that operate on data (Save, Delete, etc.). The map key matches actionKey in FormActionTrigger.triggerAction. The value is a lambda that receives the current form data and returns true if the operation succeeded.

The lambda is responsible for showing the error (dialog, errorManager) on failure - false carries the fact of failure, not its content.

Actions that do not touch data do not belong here. Closing the screen is the business of the button in the schema builder, not of the data layer.
