Incorrect validation [message #530077]

Hi all,

I have a schema file(A1.xsd, ns="http://www.example.org/A") that imports another schema (B.xsd, ns="http://www.example.org/B"). This second schema imports another schema file that has the same target namespace as A1 - A.xsd, ns="http://www.example.org/A".
After loading an XSDSchema instance for A1.xsd, the validation returns an error saying that "Type reference 'http://www.example.org/A#A_ST_01' is unresolved".
Do I have to do something with the imports before invoking the schema validation?

Tsvetan,

A1.xsd will not generally see the indirect imports of any schemas it
directly imports so I don't expect A1.xsd to see what's in A.xsd. As
such, the error message is expected unless you add an include.

    private static void updateSchema(XSDSchema schema) {
    	if (schema == null)
    		return;
    	
        for (XSDSchemaContent ref : schema.getContents() ) {

Tsvetan,

It's not supposed to see indirect imports.

Hi Ed,

That's strange.
If I iterate over the schemes tree starting from A1, invoke importSchema() on each XSDImport and then update() the schema,
the error message is not shown anymore and the type definition is resolved.

Here is the code I'm using in order to make A1 see the indirect imports:

private static void updateSchema(XSDSchema schema) {
if (schema == null)
return;

for (XSDSchemaContent ref : schema.getContents() ) {
if (ref instanceof XSDImport) {
((XSDImportImpl) ref).importSchema();
updateSchema(((XSDImport) ref).getResolvedSchema());
}
}
schema.update(true);

}

Best Regards,
Tsvetan
