I followed the given link and updated right element as 'Group Subscript' but still I am getting unexpected result. I marked pxSubscript as group subscript under pyWorkParty context page. But result is coming with multiple work party pages instead one page. I attached screenshot of my configuration, MyServicePage after parse xml. Please have look, give me an idea where is missing from my end.
What are you trying to do? Do not create workparties using parseXML or any server side artifacts. Data has to be entered using UI for onChange rules to fire that populate all the necessary workparty properties.
