I'll reply the solution to this thread on my own (with a different email address).
Did some debugging on 1.4.1 source code, my issue is in the data-config.xml file, the field column name when stored in Map object uses the DBs column casing (e.g. ID --> id): <entity name="parentEntity" ...> <field column="ID" name="XXX" /> ... <entity "childEntity" ... query="select * from jctest where ID='${parentEntity.ID}'"> ... The config above does not work because the parentEntity.ID, the "ID" token when compared in the Map object is stored as 'id'. If I change parentEntity.ID to parentEntity.id (lower case id) then it works. Perhaps the class *VariableResolverImpl *should consider a case insensitive Map get?
