Checking the types of atomic values

[Norman Walsh]

Hi Mike,

I use this method to test if the value specified for an option is
consistent with it's specified type:

public static void checkType(XProcRuntime runtime,
                             String value, QName type, XdmNode node) {
    // Code for dealing with QNames and other special cases elided

    if (typeFactory == null) {
        typeFactory = new ItemTypeFactory(runtime.getProcessor());
        types = new Hashtable<QName,ItemType> ();
    }

    ItemType itype = null;

    // Squirrel them away so I don't have to keep making new ones
    if (types.containsKey(type)) {
        itype = types.get(type);
    } else {
        try {
            itype = typeFactory.getAtomicType(type);
        } catch (SaxonApiException sae) {
            throw new XProcException("Unexpected type: " + type);
        }
        types.put(type,itype);
    }

    // FIXME: There's probably a less expensive expensive way to do this
    try {
        XdmAtomicValue avalue = new XdmAtomicValue(value, itype);
    } catch (SaxonApiException sae) {
        throw XProcException.dynamicError(45, sae);
    }
}

In 9.1 this worked fine. In 9.2, the exception never seems to be
thrown. The result is a new "avalue" with a "null" value field.

My bug, or yours?

(My test case is checkType(runtime, "string", "xs:integer", null) )

                                        Be seeing you,
                                          norm

Looks like this bug:

http://sourceforge.net/tracker/?func=detail&aid=2879248&group_id=29872&atid=
397617

which is cleared in 9.2.0.3.
