Hi, the following xquery (BaseX721, Java, embedded server):
	for $guildchar in
collection('default')/apiresponse/guild[@name="Guild"]/characters/character
	return
		for $detailchar in
collection('default')/apiresponse/character
		where $detailchar/@name=$guildchar/@name
		return
		$detailchar
produces the exception: java.io.IOException: Das Handle ist ungültig java.io.RandomAccessFile.seek(Native Method) org.basex.io.random.TableDiskAccess.readBlock(TableDiskAccess.java:519) org.basex.io.random.TableDiskAccess.readIndex(TableDiskAccess.java:502) org.basex.io.random.TableDiskAccess.cursor(TableDiskAccess.java:481) org.basex.io.random.TableDiskAccess.read1(TableDiskAccess.java:189) org.basex.data.Data.kind(Data.java:293) org.basex.query.item.DBNode$4.next(DBNode.java:350) org.basex.query.path.IterStep$1.next(IterStep.java:44) org.basex.query.iter.NodeIter.next(NodeIter.java:1) org.basex.query.path.IterPath$1.next(IterPath.java:64) org.basex.query.iter.NodeIter.next(NodeIter.java:1) org.basex.query.flwor.For$1.next(For.java:85) org.basex.query.flwor.FLWR$1.next(FLWR.java:63) org.basex.query.expr.Constr.add(Constr.java:63) org.basex.query.expr.CElem.item(CElem.java:82) org.basex.query.expr.CElem.item(CElem.java:1) org.basex.query.expr.CFrag.item(CFrag.java:1) org.basex.query.expr.ParseExpr.value(ParseExpr.java:66) org.basex.query.QueryContext.value(QueryContext.java:286) org.basex.query.func.UserFunc.value(UserFunc.java:153) org.basex.query.QueryContext.value(QueryContext.java:286) org.basex.query.func.TailFuncCall.value(TailFuncCall.java:46) org.basex.query.QueryContext.value(QueryContext.java:286) org.basex.query.func.UserFunc.value(UserFunc.java:153) org.basex.query.QueryContext.value(QueryContext.java:286) org.basex.query.func.BaseFuncCall.value(BaseFuncCall.java:55) org.basex.query.func.BaseFuncCall.iter(BaseFuncCall.java:68) org.basex.query.QueryContext.iter(QueryContext.java:275) org.basex.query.QueryContext.iter(QueryContext.java:229) org.basex.query.QueryProcessor.iter(QueryProcessor.java:74) org.basex.server.QueryListener.execute(QueryListener.java:122) org.basex.server.ClientListener.query(ClientListener.java:463) org.basex.server.ClientListener.run(ClientListener.java:148) The Query is doing ok in the BaseX Gui but fails in my Application (other queries are running like a charm). Reformulations or similar variants of the query fail the same way. Do you have a hint what could be wrong here? What should I try next? Thanks a lot for this great xml db! Best regards, Bodo

Bodo, thanks for your mail. It would be great if you could provide us with the data you're working with (which you can directly send to me), or build a small, self-contained example. Christian
