Hi,
i'm using Cayenne 2.0.4 with Oracle 10 and JDK 1.5.
Please have a short look at this code:
... dataCtx, myID are set...
SQLTemplate rawQuery =
(SQLTemplate)dataCtx.getEntityResolver().lookupQuery("myQuery");
Map<String,Object> params = new HashMap<String,Object>();
params.put("processID", myID);
rawQuery.setParameters(params);
rawQuery.setPageSize(50);
List<?> protList = dataCtx.performQuery(rawQuery);
...
On runtime the follwoing Exception ist thrown:
java.lang.IllegalArgumentException: org.apache.cayenne.query.SelectQuery:
"setRoot(..)" takes a DataMap, String, ObjEntity, DbEntity, Procedure, or
Class. It was passed a null

The mapped query is configured to fetch DataRows.
The cause seems to be the method setPageSize(): if I omit this method, all
works fine. I cannot find any restrictions for setPageSize and SQLTemplate in
the documentation.
Does anybody know what's going on here ?
Thanks in advance
Jens
