----------------------------------
Summary: Multiple levels of versioned flows might not able to load
from repository
Key: NIFI-10874
URL: https://issues.apache.org/jira/browse/NIFI-10874
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Simon Bence
Assignee: Simon Bence
With the refactoring of the registry (changing it to a component), several
necessary change was done, including the "generification" of the way included
versioned flows are handled (recognised).
Previous implementation was depending on an URI, which was not descriptive
enough for the new concept. Storage location has been introduced and now
registry client implementations are capable for determine if they are capable
to load a given flow based on this.
As a fallback mechanism, the URI was kept for the NiFiRegistry based
implementation. A bug has been introduced with this mechanism, namely: the
ProcessGroupResouce#createProcessGroup method works with version information
from the UI, which has no knowledge of this. In order to guarantee that the
given information is stored during flow creation (here: loading flow from
external source) we need to guarantee the transition of this information.
