[flexcoders] the commit method of LCDS doesn't commit deleted child object. Is this normal?

[Shigeru Nakagaki]

When autoCommit is false, the commit method of LCDS doesn't commit 
deleted child object (hierarchical destination, many-to-one). If the 
case is adding child object, the commit method creates new child 
object. Is this normal? Do we have to delete child object manually if 
autoCommit is false?
