Hmmm. I thought we fixed this a long time ago. In fact, here is the code,
from SimpleResourcePropertyCollection.java, that is causing the fault:
if (!isNillable)
{
for (int n = 0; n < instances.length; ++n)
{
//
// check for child elements, attributes, and text, all of
// which qualify an element as "not null"
//
if (!instances[n].hasChildNodes() &&
!instances[n].hasAttributes() &&
XmlUtils.extractText(instances[n]) == null)
throw new SchemaValidationFault(message);
}
}
As you can see, it includes attributes in the check for 'null' elements
(note: the error message needs to be updated). Since the MCR elements have
attributes, this shouldn't be a problem. I will have to look into this
more. In the meantime, you can hack around the problem by removing the
'nillable="true"' attribute from the MCR schema defintion.
