Issue when using Combobox with showFilterEditor and multiple

[zeratus]

I've found an error when combining selectItem/combobox with the following attributes: showFilterEditor:true and multiple:true.
The symptom is that the picklist is not shown from the second click.

In Chrome developer tool i get:

Uncaught TypeError: Cannot call method 'getValueFieldName' of undefined
isc_c_EventHandler_dispatchISC_Core.js:1662
(anonymous function)
ISC_Core.js:299Uncaught TypeError: Cannot call method 'getValueFieldName' of undefined
isc_c_Class_fireCallbackISC_Core.js:299
isc_c_Timer__fireTimeoutISC_Core.js:1276
(anonymous function)

In the SmartClient Developer console i get the following:

Sample code for testing, starting from http://www.smartclient.com/#comboBoxStyled

isc.DynamicForm.create({
ID:"testForm",
width: 500,
fields : [
{
    name: "fItemName", title: "Item Name", 
    editorType: "comboBox", 
    optionDataSource: "supplyItem", 
    displayField:"itemName",
    valueField:"itemID",
    multiple:true, 
    multipleAppearance : "picklist",
    pickListProperties: {
       showFilterEditor:true
    }
}]
});

Issue is present in version 8.1 and also in 8.2.
Thanks
