Philipp Zehnder commented on STREAMPIPES-449:
---------------------------------------------
Hi,
I tested it locally, also with the System.out.println statement.
* the declare model is called when the service is started
* The on invocation is called on pipeline start
* For each event the onEvent Method is triggered
* And once the pipeline is stopped the onDetach is called
For some reason the declare model is called quite often, we have to look into
this because this should not be the case.
Did you search your logs? Maybe the output is hidden between some other logs in
the console.
Is the data processed correctly in StreamPipes or is there also a problem?

> The processors in this module use the old API, where 3 classes are required
> for a single processing element.
> These should be updated to use StreamPipesDataProcessor instead of
> StreamPipesDataProcessor.
