Hi guys,
as per the CustomTaskInstance example, I am subclassing TaskInstance, and adding a couple of simple properties, I have created a new class subclassing TaskInstance, and the hibernate mapping field to go with it...
What I am unsure about, is how the hibernate mapping file relates to my MySQL database, do I need to modify the original TaskInstance table in MySQL to reflect the changes (fields added) in my new extended class, or do I create a new table JBPM_NEWTASKINSTANCE that is a duplicate of JBPM_TASKINSTANCE table but with the new fields added.
My hibernate mapping file is listed below...
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping default-access="field">
<subclass name="com.mycomp.taskinstance.NewTaskInstance"
extends="org.jbpm.taskmgmt.exe.TaskInstance"
discriminator-value="C">
<property name="someVariable1" column="SOMEVARIABLE1_" />
</subclass>
</hibernate-mapping>
When I run my unit test I see...
INFO Configuration : Reading mappings from resource : com/mycomp/taskinstance/NewTaskInstance.hbm.xml
INFO HbmBinder : Mapping subclass: com.mycomp.taskinstance.NewTaskInstance -> JBPM_TASKINSTANCE
I suppose the NewTaskInstance should map to either a modified JBPM_TASKINSTANCE or to JBPM_NEWTASKINSTANCE ?
And finally of course the test bombs out with...
WARN JDBCExceptionReporter : SQL Error: 1054, SQLState: 42S22
ERROR JDBCExceptionReporter : Unknown column 'newtaskins0_.SOMEVARIABLE1_' in 'field list'
because I either have not added the new field to JBPM_TASKINSTANCE, or have not added the new table required.. (not sure which).
If someone could give me a pointer as to the process of adding the new field in the table, or adding a new table I would appreciate it,
thanks
Ross
