Task #6559 First experiments with a casapy recipe. Works in basic form for now but with workarounds for proper return values to the pipeline. casapy does not seem to return in a usual way. when there is an error the pipeline does not recognize the process has finished. without the encapsuleting in a shell script even a successful run does not return. Needs more checking and a cleaner way of calling. Maybe integrate casa python classes to the Lofar install? Loops: Nested loops work. Breaking a loop only works for one full cycle. Outputdictionaries you reference with step.output.stepval are now always for the last call of that step.
