    Empty value for PickTreeItem

    Is it possible to have an empty value for a PickTreeItem after selecting a value?

    If you look at the example at https://www.smartclient.com/smartcli...e/?id=pickTree, it starts with an "empty value", but after selecting it, it cannot be changed back to an empty value or can it?

    If you use a valueField *and* displayField, the valueField can be null and the displayField can have something like "[Empty]" or whatever you want to show to the end user for an empty value.
