Philipp Zehnder commented on STREAMPIPES-449:
---------------------------------------------
Hi,
the declareModel is called when the component is registered and installed the
backend.
The onInvocation is called when the pipeline containing this element is started
and the onEvent is then called for each event of the data stream.
I hope this helps. So if you use the component within a pipeline your log
messages should be printed. Does this work?
