Hi Martin,

during our tests with the DataGenerator we had to drop our database schema several times. When the schema is empty and we execute jsonTexoResource.query("select u from User u", new HashMap<String, Object>(), 0, Integer.MAX_VALUE); the server returns an error.
The exception that is thrown on the server side looks like this:
java.lang.ArrayIndexOutOfBoundsException: -1
	at java.util.Vector.elementData(Vector.java:730)
	at java.util.Vector.remove(Vector.java:828)
	at org.eclipse.emf.texo.server.service.RetrieveModelOperation.internalExecute(RetrieveModelOperation.java:97)

	at java.lang.Thread.run(Thread.java:722)


If I execute http://localhost:8080/praesto/jsonws/User just as a GET call, it returns
{
"endRow": "-1",
"_eclass": "response|ResponseType",
"totalRows": "0",
"status": "success",
"startRow": "0",
"data": [(0)],
"_title": "success"
}
so I assume the right behaviour of the query call above should return an empty resource, but shouldn't throw an error, right?

Best regards
Bastian

Seems to be a clear bug, will solve that in parallel with the other one you entered.
