Before Container Creation#

Run a workflow for each Container before it is created.

Event Context#

The event provides the typed Container field to child tasks. Select it in the value editor directly; no entity-type condition or type conversion is required.

Before Container Creation

Use the pending Container in If to check its CapacityPerPosition against your configured carrier rule. Use Throw error to reject an invalid capacity before the container is created.

Behavior#

The handler runs once for each Container in the native creation collection, in collection order. An empty collection runs no handlers. Singular and generic creation services that reach this collection boundary use the same event.

The Container may not yet have a persisted ID. Leave Persist false when updating its properties so the enclosing creation operation saves the pending values.

The handler runs inside the creation transaction. An error can cancel or roll back creation. An After event runs after the operation boundary, while the transaction is still active.
