Andy Grove commented on TUSCANY-1397:
-------------------------------------
You're right, the spec doesn't currently cover this.
Perhaps the spec should be amended to state that calling createDataObject()
with a property that does not exist should throw an IllegalArgumentException ?
Alternatively it could just demand-create the property using a vendor-specific
open DataObject type. That seems more consistent with the behaviour of the
set<T>() calls.
I'm going to raise a JIRA against the spec, cross-referencing this JIRA.

> Calling createDataObject( "foo" ) where the data object's type does not
> define a property "foo" causes a null pointer exception in
> DataObjectUtil.createDataObject(DataObject dataObject, Property property,
> Type type) because it attempts to call property.isContainment without
> checking if the property is null.
> Calling createDataObject( "foo" ) on an open type should create an on-demand
> property. If the type is not open and the property does not exist then an
> exception should be thrown.
> Thanks,
