The problem here are virtual properties that are not stored via a hashtable in the object. The problem (of course) is that the read (RW) handler creates a temp container for the property value. As a consequence the changed value needs to be written back using the write handler. To accomplish that we have two options: a) Chnage the signature of the read handler so it returns whether ot not the prop is a virtual prop and use write after the change if so. b) Somehow identify the situation and print out a E_ERROR. > One is more vicious, see ilia post and the mail I forward to you and > Zeev.
