[NIFI-1318] For each Processor in the canvas we end up with 4 instances of such Processor

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 0.4.0

Description

Also, 4 calls to Processor.initialize(..) method are made
Can't imagine it to be intentional.

The first call is during documentation setup and is done even when the processor is not in the canvas.
For each subsequent call see stack trace below:
