Hi,

Yes this is correct as by default parameters are required. If you want
to make it optional then you would have to set optional to true.

<attribute name="partyList" mode="OUT" type="List" optional="true"/>

There are plenty of examples on that in the framework, just browse thru
the services.xml definitions, and also have a look here - very good
examples http://ofbiz.apache.org/docs/services.html
