Attempting to delete transformation base generator or multipart inner component gets a "Sequence contains no elements" message
When all DN components are deleted, the DN generator defaults to either the Schema Key or the Entity Id generator (depending on the schema key). When you attempt to delete this one in a transformation, you receive a "Sequence contains no elements" message in the temp data message. This has no operational impact other than this message appearing in this case.
However, this also occurs when attempting to delete a component from a multipart component results in the same error, and this does affect configuration. You can work around this currently by deleting the multipart completely and recreating it.
