commit option B does not work with CMP 1.x
------------------------------------------
Key: JBAS-1386
URL: http://jira.jboss.com/jira/browse/JBAS-1386
Project: JBoss Application Server
Type: Bug
Components: CMP service
Versions: JBossAS-4.0.1 Final
Environment: jdk 1.4.2 on linux
Reporter: Peter Doornbosch
Assigned to: Scott M Stark
When accessing a CMP 1.x entity bean with the commit option set to B, and the
bean is already loaded (by a previous invocation), the bean is not loaded again
from the database (as it should with commit option B). This can be easily
verified by deploying such a bean and enabling sql logging.
The cause of this bug is in the following method from JDBCCMP1xFieldBridge:
public void resetPersistenceContext(EntityEnterpriseContext ctx)
{
if(isReadTimedOut(ctx))
{
JDBCContext jdbcCtx = (JDBCContext)ctx.getPersistenceContext();
jdbcCtx.setFieldState(jdbcContextIndex, new FieldState(jdbcCtx));
}
}
Assigning a 'new FieldState(jdbcCtx)' to the jdbcCtx effectively does nothing,
because JDBCCMP1xFieldBridge.FieldState delegates to EntityState and the
EntityState is not affected by this call. Hence, after this method, the state
of the field is still "loaded", and thus this field is not part of the
load-iterator created by JDBCEntityBridge.
I think the fix is rather easy: just reset the field flags explicitely (as it
is done in the cmp 2.x case), e.g.
jdbcCtx.getEntityState().resetFlags(tableIndex);
