Multicombo with suggest

Hello all,

here my new question. This is the code:

 view:"multicombo", 
    label:"Name", 
    tagMode: false,
    suggest:names,
    tagTemplate: function(values){
        return (values.length? values.length+" item(s) selected":"");
    },
getValue:function(){
    	var value=webix.ui.combo.prototype.getValue.call(this);
        return value?this.getList().getItem(value)[this.config.valueField]:value;
    }

My question is how to get the value of the combo when nothing is selected. The Combo is empty and the getValue() function only ends in a javascript error: t.join is not a function. I tested following functions: getText, getItemText(), getPopup().getList()…they all end in an error…So please tell me how to get the empty String(which i guess its an empty string) out of the Combobox.
Thx!

@pulsedrone
did you try to set an empty array as options?
{options: []}

no, but this would not solve the problem because i need all data in it. But i will remove the suggest property and use options instead like here: Code Snippet
This should work hopefully.
