Alexey Loubyansky reassigned JBAS-1386:
---------------------------------------
Assign To: Alexey Loubyansky (was: Scott M Stark)
> 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
> Assignee: Alexey Loubyansky
> Attachments: employee-ejb.jar
>
>
> 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);
