[jira] [Commented] (NIFI-7622) updateParameterContext
NullPointerException on StandardProcessGroup.java:4220
[ https://issues.apache.org/jira/browse/NIFI-7622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17154659#comment-17154659 ]
Eric Secules commented on NIFI-7622:
------------------------------------
I think the problem might be with creating the snapshot file for the outer flow. I noticed that it assigned all the same parameter context to each process group even though I did not change the parameter context on the versioned process groups from our common flows bucket

> I am getting this null pointer exception when importing one versioned flow from a registry 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.
