Michael, Got a NPE in TypeChecker.staticTypeCheck using Saxon 8.1.1. Not sure what all the scenarios are this NPE occurs. But after doing some simplifications I've been able to reduce it for one at least to something as follows: for $a in doc("a.xml")//a return for $b in doc("b.xml")//b[$a != .] order by fn:data($b) return $b I've the impression it's somehow a combination of the predicate and fn:data. The full stack trace is as follows: java.lang.NullPointerException at net.sf.saxon.expr.TypeChecker.staticTypeCheck(TypeChecker.java:76) at net.sf.saxon.functions.SystemFunction.checkArgument(SystemFunction.java:93) at net.sf.saxon.functions.SystemFunction.checkArguments(SystemFunction.java:82) at net.sf.saxon.expr.FunctionCall.analyze(FunctionCall.java:111) at net.sf.saxon.expr.LetExpression.analyze(LetExpression.java:36) at net.sf.saxon.expr.ForExpression.analyze(ForExpression.java:92) at net.sf.saxon.query.XQueryExpression.<init>(XQueryExpression.java:57) at net.sf.saxon.query.QueryParser.makeXQueryExpression(QueryParser.java:54) at net.sf.saxon.query.QueryProcessor.compileQuery(QueryProcessor.java:163) at net.sf.saxon.query.QueryProcessor.compileQuery(QueryProcessor.java:190) at net.sf.saxon.query.StaticQueryContext.compileQuery(StaticQueryContext.java:168) at net.sf.saxon.Query.doMain(Query.java:318) at net.sf.saxon.Query.main(Query.java:69) Thanks, Marc
