I asked this question in SO. Non of the answers I got over time satisfied me, and it wasn't that important for me to start a bounty. Eventually I resolved the problem by myself, and it wasn't exactly a solution that occurred in either of the answers.
Now I had a big dilemma: What to do with the question? I have a solution, but it's sown up a lot to my special case. Should I answer my own question? If I did, should I accept my answer? Should I just close the question? Or should I do nothing.
Moreover, is there a convention about answering your own question?
Short Notice: I eventually did answer my own question, and accepted the answer. But if the best solution would be to delete the question or the answer, I will do that.
