Subject [jira] Reopened: (JCR-644) Node.isNodeType() throws if namespace is not defined.
Date Thu, 23 Nov 2006 18:34:03 GMT
     [ http://issues.apache.org/jira/browse/JCR-644?page=all ]

Jukka Zitting reopened JCR-644:
-------------------------------

             
I disagree.

Assume that in the context of the client application the "foo" prefix corresponds to the namespace
"MyNamespace". Now, it could be that "MyNamespace" is actually mapped to the prefix "bar"
in my repository for some local administrative reason. Then, a node with the node type "{MyNamespace}MyNodeType"
would return false for node.isNodeType("foo:MyNodeType"), which would obviously be incorrect
from the client perspective.

If a client doesn't check the existence of the namespace with session.getNamespacePrefix("MyNamespace")
or explicitly align the naming context with session.setNamespacePrefix("foo", "MyNamespace"),
it implicitly assumes that the repository already contains both the namespace *and* the correct
prefix mapping. If these assumptions are incorrect, throwing an exception is IMHO the best
the repository can do.

> throws an exception if 'foo' is not defined. this is incorrect since an application should
not need to check if the namespace exists before checking for a nodetype. it should return
false.
