[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-1054) "No type name" MappingException message is far too cryptic

"No type name" MappingException message is far too cryptic ---------------------------------------------------------- Key: HBX-1054 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1054 Project: Hibernate Tools Issue Type: Improvement Components: hbmlint Affects Versions: 3.2.1 Reporter: Darryl Miles Priority: Minor Having to resort to stepping into Hibernate code to find where this exception is making hard work for developers. Basically the problem is that the message does not inform the developer exactly which class and which column has the problem (so we need some context information emitted with the "No type name"). The rest of the method does have code to generate a useful exception message if(result==null){} http://fisheye.labs.jboss.com/browse/Hibernate/core/tags/hibernate-3.3.0.... public Type getType() throws MappingException { if (typeName==null) { throw new MappingException("No type name"); } Type result = TypeFactory.heuristicType(typeName, typeParameters); if (result==null) { String msg = "Could not determine type for: " + typeName; if(table != null){ msg += ", at table: " + table.getName(); } if(columns!=null && columns.size()>0) { msg += ", for columns: " + columns; } throw new MappingException(msg); } return result; } Example mapping that cause the problem: <class name="domain.MyData" table="my_data"> <id name="myDataId" type="long" column="my_data_id"> <generator class="native" /> </id> <list name="abcList" table="my_data_list" cascade="all-delete-orphan"> <key column="my_data_id"/> <index column="sort_order"/> <element column="value" not-null="true" /> <!-- type="" was missing here! --> </list> </class>
