Description Yonghe Yan

2008-10-17 14:31:29 EDT

Build ID: M20080911-1700

Steps To Reproduce:
After an observable that is used in a MultiValidator has be changed, the validate() method may or may not be called to re-evaluate the status.

This may be caused by a bug in MultiValidator.revalidate() method. The dependencies are generated in a thread and are consumed in another thread. However, there is no producer-consumer synchronization for these two thread. As a result, dependences may get lost randomly because of threads racing.

I don't follow you.  Could you provide a snippet, or a simple scenario that describes the problem?

Also, take a look at bug 237857 or bug 251003 and see if those are related to this bug.

I have a suspicion this is caused by bug 251003, which was just fixed in HEAD.  Could your try your application again and see if these latest changes fix your problem?

Since we haven't heard any further information from the reporter I will assume this is a dupe of 251003
