Summary 0000393: can't traverse many-to-one paths in amber (resin 3) ejb-ql
Description RSN-439
Given the following ejb-ql:

SELECT a FROM schemaA a, IN (a.schemaB) b where b = ?1

if a has a many-to-one relationship with b then the query dies with the following error:

com.caucho.amber.query.QueryParseException: collections in FROM may not be sub-collected. in "SELECT a FROM schemaA a, IN(a.schemaB) b WHERE b = ?1" at com.caucho.amber.query.QueryParser.error(QueryParser.java:1490) at com.caucho.amber.query.CollectionSchemaExpr.createField(CollectionSchemaExpr.java:65) at com.caucho.amber.query.QueryParser.parseSchema(QueryParser.java:671) at com.caucho.amber.query.QueryParser.parseFrom(QueryParser.java:518) at com.caucho.amber.query.QueryParser.parseSelect(QueryParser.java:264) at com.caucho.amber.query.QueryParser.parse(QueryParser.java:239) at com.caucho.amber.connection.AmberConnectionImpl.parseQuery(AmberConnectionImpl.java:963) at

I have traced this through the source and this error ("collections in FROM may not be sub-collected") is hardcoded into CollectionSchemaExpr.java. It looks like the coding was simply never finished. So an ejb query can no longer traverse a many-to-one path anymore, which pretty much makes the IN clause of ejb-sql useless. In resin 2, the join was created easily and works.

Can you get this completed and into 3.0.15???

cheers
