Subject Re: hsqldb and NullPointerException

This is what I got:

In static initializer
Torque initialized
Map builder initialized
BasePeer: tableName=patient
BasePeer: dbName=cardiobip
DBMap tables: {ID_TABLE=org.apache.torque.map.TableMap@ffd135}
tableMap==null
Exception occurred during event dispatching:
 
Everything seems OK untill I call the tableMap. Looks like no
tableMaps are added to dbMap, except for ID_TABLE.
I use only one database, and that's the default.
