Hi Abraham
From your initial post, looks like you are having two problems :
- Using DAS, a call to applyChanges succedds, but the account
row does not get updated.
- When you use SCA to create a DAS component, you are having a
PassByValueInterceptor exception
I have committed a organization-das sample, all based on the
application you provided under TUSCANY-2525, under svn revision
684376.
Note that I'm building the sample im multiple steps, isolating the
areas involved in each issue. Also, note that I'm using derby, but
changing back to Oracle should be easy, just change the
ConnectionHelper to create the proper Oracle connection.
Right now, I have the DAS piece working ok, and it would be good if
you could verify this in your Oracle environment by running the
OrganizationTestCase. While I wait for your feedback, I'm going to
move to incorporate the SCA into the sample.
Thanks
