Mapping attributes with default values

starksm64 Jul 14, 2005 12:55 AM

See http://jira.jboss.com/jira/browse/JBXB-32 for an example issue. Currently if a schema defines attributes with default values, the defaults are not being set on the associated java object unless explicitly present in the xml document. This seems incorrect as it essentially makes the defaults non-existent.

Is this info available from the schema api?

The answer is yes, its available via the XSAttributeUse.getConstraintValue, which for the attributes in the schema shown in the JBXB-32 issue are:

Attr(type): , Required: false, ConstraintType: default, ConstraintValue: java.lang.String Attr(editor): , Required: false, ConstraintType: none, ConstraintValue: null Attr(replace): , Required: false, ConstraintType: default, ConstraintValue: true Attr(trim): , Required: false, ConstraintType: default, ConstraintValue: true

Currently it looks like we are throwing this info away in the call to XsdBinder.bindAttributes. I think this is something that needs to be implemented for the 4.0.3 release so I'll look into it while Alexey is out.

I have added support for mapping missing attributes with defaults to head, and the org.jboss.test.xml.jbxb.defaults.DefaultsUnitTestCase is passing, but the org.jboss.test.xml.JNDIBindingUnitTestCase continues to fail because the java object stack and type stacks seem to be out of synch when it comes to the JNDIBinding object and associated jndi:binding element.

This is now working in head. After discussing some of the current behavior and getting it clear and documented this will be ported to 4.0 for the 4.0.3 release.
