Mega Api Java : Problems to get linked collection of SequenceFlow type

[Accelinn]

Hello,

I use Mega API to communicate via Java Application ( I'm include Mega Vocabulary in my projects ).

I'm retreive all mega object like "Business Process", "Organizational Process" etc... And i navigate to linked collection like this :

But when i try to get predecessor/successor of sequenceFlow megaObject, Mega API return me empty list...

public static final String MAE_Successor = "~jqV6ztHL71M0[Sequence Flow.Successor]";
public static final String MAE_Predecessor = "~2sV6luHL79O0[Sequence Flow.Predecessor]";

When i check the sequence Flow element in the Mega Repository, he has only one predecessor/successor. But MegaApi return me empty list.

When i launch :

sequenceFlow.isMemberName(MegaSequenceFlow.MAE_OwnerElement); => resutl is True

sequenceFlow.isMemberName(MegaSequenceFlow.MAE_Predecessor); => result is True

sequenceFlow.getAttribute(MegaSequenceFlow.MAE_Predecessor); => return null

sequenceFlow.getCollection("TestHackValue") => Launch exception

sequenceFlow.getCollection(MegaSequenceFlow.MAE_Predecessor).size() => 0 return empty list !!!!!!

It's a bug in Mega API ?

Can someone help me ?

I am new to filters: but i usually just use oRoot.GetSelection("") to get specific type of objects.

Hi

mgObject.Getcollection("Owned Element") returns objects of the abstract metaclass "BPMN Owned Element".

You can filter this result to retain only sequence flow objects:

Megacollection mgColelction = mgObject.getCollection(BusinessProcess.MAE_OwnedElement).Filter("~jsV6VsHL7vJ0[Sequence Flow] ");

Best regards
