Thomas,

I don't think you can have an object tell it's parent to remove itself. I think you should just to a this.Release() instead.

>Textbox LostFocus Event:
>
> loObject = This.MasterObject
> If Type ('loObject') = "O" And loObject.BaseClass = "Label"
> loObject.Caption = This.Value
> This.Parent.RemoveObject (This.Name)
> * Release This && first version
> EndIf
> <- at this point the error-message appears
>
>What's wrong? Any help appreciated
