Asking the community is a really nice feature in Mendix. But sometimes it takes the community very long to answer questions and in the meantime you solve your question on your own.
It would be very helpful, if it would be possible to accept his own answer to a question. It just doesn’t make sense to deactivate this functionality, just because the answer was submitted by the questioner himself. This would definatly help other users with the same problem, when they find the question allready solved, not just commented.
