That is not expected behavior. However, its impossible to say what you may have done wrong in your custom entity implementation to cause it without seeing any code. If you're an ADN member, then you're welcome to submit your question via DevHelp Online on the ADN website. If not, then someone may be willing to take a look at your code if you post it here. (
In either case, please don't submit any code you consider to be confidential).
