Apologies for the inconvenience. Could you please let us know the exact thread you facing the issue with? Normally we lock the threads when the issue is resolved so that in future unrelated questions are not appended on the thread. This helps us in keeping the thread relevant to the topic and also make sure that new questions are created on the under the right title, so that it becomes more accessible to all users. We do understand the importance of the discussions and how much they are helpful. In such cases we categorize those as "discussions threads" which are never locked. Normally you have an option to mark the issue as a question or a discussion while creating the thread. In case if a thread has been categorized wrongly, kindly let us know. We will rectify the issue.
For instance, this relatively recent question still has not been resolved, and whether someone provides an answer or I figure it out on my own, I think this topic could be of use to others trying to develop UDB components (if there is a definitive answer one way or the other).
