Eric Secules updated NIFI-7622:
-------------------------------
Description:
I am getting this null pointer exception when importing one versioned flow
which contains another versioned flow and each uses different parameter
contexts.
I am using version 1.11.4 of NiFi
This error is blocking me from developing flows which comprise common
components and project-specific components that use their own parameter
contexts.
