I'm up and running with Loren's tests too. Nice stuff. Yes, it seems we have issues with asynchronous modifications from within different threads. One thread is the model's ResourceChangeListener which updates the model on resource modifications and another thread is the Eclipse UI thread with Spring IDE UI's write access to the model [configuration dialogs -> BeanProject.setConfigs()]. We have to make the bean model thread safe by introducing some locking mechanism and batch operations as the Java model does. Modifications to the beans model could leverage Eclipse 3.0's new job scheduling API [JobManager.newLock()]. Additionally I ran into problems with the validator running while the workspace tree is locked (used to re-validate on changes of bean classes in the Java model). In this state the workspace (which supports multiple concurrent readers but only one concurrent writers) does not allow modifications, e.g. manipulation of problem markers. So I have to introduce batched validations which are running after the workspace tree is unlocked again. This is done most easily with the job API too. But this means we have to drop support for Eclipse 2.x!!! We will have a lot of complains from Eclipse 2.x or WSAD users. What do you think? I have updated the CVS head of Spring IDE with the following new features: - IBeansProject has a new method "Collection getConfigs(String className)" to retrieve all IBeanConfig instances which are using the specified bean class -> required for re-validation of IBeanConfigs after modifications of bean classes in the Java model (JIRA issue #IDE-21) - UI's editor context menu actions (open type and show in view) have an action set and commands with configurable keybindings (JIRA issue #IDE-4) Cheers, Torsten On 17.09.2004, at 23:48, Loren Rosen wrote: > I have occasionally seen intermitant assertion failures, though not in > that particular place.
