Hello Folks,
I have been working on a BMPN process that at key points uses the Call activity to execute other BMPN processes, the called activities make use of the DelegateVariableMappping solution in order to handle the input and output/result variables from the sub process to the main process.
At one such call activity i found that i required a Multi Process Call Activity to execute a sub process for a defined list of objects.
I expected that the mapping of the results would fail based on the documentation that i found here : multi-instance-io-mapping
Currently i have managed to get the results i wanted via my DelegateVariableMapping class by checking and filling a map variable on the parent process with the individual results of the different types.
The result:
{
type1_outcome => ObjectValue [value={type1A=SUCCESS, type1B=FAILED}, isDeserialized=true, serializationDataFormat=application/x-java-serialized-object, objectTypeName=java.util.HashMap, serializedValue=160 chars]
type2_outcome => ObjectValue [value={type2A=FAILED, type2B=SUCCESS}, isDeserialized=true, serializationDataFormat=application/x-java-serialized-object, objectTypeName=java.util.HashMap, serializedValue=152 chars]
...
}
The Delegate code:
public class MergeMultiProcessResults implements DelegateVariableMapping {
@Override
public void mapInputVariables(DelegateExecution superExecution, VariableMap subVariables) {
// copy all parent variables to the sub process
subVariables.putAll(superExecution.getVariables());
}
@Override
public void mapOutputVariables(DelegateExecution superExecution, VariableScope subInstance) {
// extract information and add to the parent process
String name = subInstance.getVariable("type") + "_outcome";
Map<String, String> results = (Map<String, String>) superExecution.getVariable(name);
if (results == null) {
results = new HashMap<String, String>();
}
results.put((String) subInstance.getVariable("typeValue"), (String) subInstance.getVariable("outcome"));
superExecution.setVariable(name, results);
}
Any thoughts about this implementation, as im controlling everything i guess it is ok but would like to gather other users opinions
