problem - itemEditor is not refreshed on the screen when dataProvider is changed.

Instance of SelectDivisionInput is used as itemEditor for component id="divisions" (extends LayoutComponent)

Method creationComplete is OK - dataProvider is populated; after that 

on some event changeFilter is called and after some work in method resultLoad dataProvider is changed (i've watched it on debugging)

but that changes does NOT appear on the screen.

<component:EMultiSelectRowArray id="divisions"

                                        data="{filter.divisions}"

                                        idDataName="divId"

                                        textDataName="divName"

                                        changeEventName="objectIdChanged"                           

                                        width="100%">

            <component:itemEditor>           

                <mx:Component>

                <directories:SelectDivisionInput objectId="{data.divId}"

                                                     text="{data.divName}"                                                                                                                                                         

                                                     editable="true"
