Issue to get AccessSelection of composite curve?

Hi,

I have created a feature using the composite curve. The newly created feature is a child of the composite curve. While creating the feature I got AccessSelection() of the composite curve. After getting AccessSelection , I have called GetEntitiesToJoin() and after that I have released selection using ReleaseSelectionAccess() API. However, while editing the feature I have called AccessSelection() but I could not get the selection and bool returned by the AccessSelection() API is false.

I could not understand the problem?
