I've checked the code we have in such combo class

I check if the controlsource is not empty then set ListIndex to 1 (in the Initialize method of this class) then later

.rowsourcetype = 5 && Array
.rowsource = "This.aRowSource"


That's all. I don't think we have a problem of combo losing the value. May be it loses its controlsource ?
