Caroline Maynard updated TUSCANY-1202:
--------------------------------------
Attachment: Tuscany-1202.patch
I'm not convinced that it's worth the trouble of caching the
changesummaryobject, given the problems it causes. This patch eliminates the
cache, calculating the changesummaryobject by walking up the containment tree
when necessary instead.

> Key: TUSCANY-1202
> URL: https://issues.apache.org/jira/browse/TUSCANY-1202
> Project: Tuscany
> Issue Type: Bug
> Components: C++ SDO
> Affects Versions: Cpp-current
> Environment: PHP
> Reporter: Caroline Maynard
> Attachments: Tuscany-1202.patch

>
> Like Tuscany 1147, this problem is seen running the SDOAPITest PHPUNIT
> testcase. The scenario is the same, but this time ChangeLogging type objects
> exist in the tree (note that Logging does not need to be turned on to see the
> problem). As with 1147, the problem is seen when the code using Tuscany holds
> references to objects at different levels in the tree, such that they are
> held after the root object no longer exists.
> It's the standard company->departments->employees setup. When the company is
> dropped, the Tuscany code does reset the container and the applicable change
> summary for the department. But it doesn't drill down and do the same for the
> employee. The consequence is that the employee still has a changesummary
> pointer to the company's changesummary. When that gets referenced, in this
> testcase when unsetting the employee from the department, the changesummary
> value is tested and an AccessViolation occurs.
