[GitHub] nifi issue #1478: NIFI-3446 FlowConfigurationDAO Changes
Github user patricker commented on the issue:
https://github.com/apache/nifi/pull/1478
@joewitt @pvillard31 I made the changes and squashed the commits since about 50% of my changes were basically rolled back to the original code.
One issue... it doesn't work anymore. I'm looking for a little guidance on what I might have missed (of course since there is no functional change maybe it never worked and I was testing with an old build?). The error makes it sound like it's a standard, 'can't find your class' error. Since the code all lives in the same JAR I added a resource file to register the interface and class (it's in the commit), which made no difference.
Here is the stack trace I'm getting:
