http://nagoya.apache.org/bugzilla/show_bug.cgi?id=11571 xs:keyref within xs:key scope fails with NullPointerException. Inverse always validates. Summary: xs:keyref within xs:key scope fails with NullPointerException. Inverse always validates. Product: Xerces2-J Version: 2.0.2 Platform: PC OS/Version: Windows XP Status: NEW Severity: Blocker Priority: Other Component: XML Schema Structures AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] An excerpt from http://xml.apache.org/xerces2-j/xml-schema.html: "We have interpreted the specs as requiring <keyref> Identity Constraints to refer to <key> or <unique> identity constraints within the scope of the elements to which the <keyref> is attached. This interpretation is at variance with the Schema Primer, which contains an example with a <keyref> declared on an element used inside the element of its corresponding <key>" When <key> does infact exist within the <keyref> the exception below is thrown. This exception is similar to the exception thrown with bug 7315. Conversely, when <key> is within <keyref>, validation is always true under all conditions. One other problem, is the deviation of the Schema Primer. XMLSpy correctly validates <keyref> within <key>. In fact, XMLSpy has trouble with the inverse. My particular needs require both parsers to properly validate the schema. Please consider changing how Xerces interprets specs for <key> and <keyref> Exception Encountered: Exception in thread "main" java.lang.NullPointerException at org.apache.xerces.impl.xs.XMLSchemaValidator$ValueStoreBase.append (XMLSchemaValidator.java:3218) at org.apache.xerces.impl.xs.XMLSchemaValidator$ValueStoreCache.transplant (XMLSchemaValidator.java:3761) at org.apache.xerces.impl.xs.XMLSchemaValidator.handleEndElement (XMLSchemaValidator.java:1976) at org.apache.xerces.impl.xs.XMLSchemaValidator.endElement (XMLSchemaValidator.java:694) at org.apache.xerces.impl.XMLNamespaceBinder.handleEndElement (XMLNamespaceBinder.java:853) at org.apache.xerces.impl.XMLNamespaceBinder.endElement (XMLNamespaceBinder.java:643) at org.apache.xerces.impl.dtd.XMLDTDValidator.handleEndElement (XMLDTDValidator.java:2978) at org.apache.xerces.impl.dtd.XMLDTDValidator.endElement (XMLDTDValidator.java:918) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.handleEndElement (XMLDocumentFragmentScannerImpl.java:11 45) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanEndElement (XMLDocumentFragmentScannerImpl.java:988) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher .dispatch(XMLDocumentFragmentS cannerImpl.java:1446) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument (XMLDocumentFragmentScannerImpl.java:333) at org.apache.xerces.parsers.StandardParserConfiguration.parse (StandardParserConfiguration.java:529) at org.apache.xerces.parsers.StandardParserConfiguration.parse (StandardParserConfiguration.java:585) at org.apache.xerces.parsers.XMLParser.parse(XMLParser.java:147) at org.apache.xerces.parsers.DOMParser.parse(DOMParser.java:221) at org.apache.xerces.jaxp.DocumentBuilderImpl.parse (DocumentBuilderImpl.java:201) at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:161) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
