I have a process with nested operators (Loop Example). I have to get an output from root operator. Loop example is a last operator and in XML defenition is
in code I have
<connect from_op="Loop Examples" from_port="output 1" to_port="result 1"/>
<connect from_op="Loop Examples" from_port="output 2" to_port="result 2"/>
But it throws NullPointerException.
IOObject o1 = process.getRootOperator().getOutputPorts().getPortByName("result 1").getAnyDataOrNull(); // or getData()
IOObject o2 = process.getRootOperator().getOutputPorts().getPortByName("result 2").getAnyDataOrNull(); // or getData()
Complete process is defined below.
