Nissim Shiman commented on NIFI-7123:
-------------------------------------
We were seeing the onPropertyModified() being run when we hadn't changed any
properties, so I thought it was an issue.
I guess it can be a feature as opposed to a bug, though.
Maybe the doc could be updated to reflect this :
[https://github.com/apache/nifi/blob/master/nifi-api/src/main/java/org/apache/nifi/components/ConfigurableComponent.java#L55]
(i.e. take out the part where it is called for "each property that is not set
to the default value" as it is called even when the property is still the
default value)
> onPropertyModified() is called on nifi start up even when properties have
> never been modified
