Subject [jira] Commented: (TUSCANY-1397) createDataObject() throws NPE if property does not exist
Date Fri, 03 Aug 2007 21:29:52 GMT

    [ https://issues.apache.org/jira/browse/TUSCANY-1397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12517639
] 

Fuhwei Lwo commented on TUSCANY-1397:
-------------------------------------

The patch looks fine except the client code needs to handle IllegalStateException when invokes
DataObject.createDataObject(String propertyName, String namespaceURI, String typeName) with
non-existent type definition in the default helper context and IlegalArgumentException when
the dataobject type is not open. Those exceptional behavior is not defined in the 2.1 spec
either so I think whatever patch we have here is sufficient.

> 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,
