[Ext]讓 ItemSelector 能透過 setValue() 來指定項目

// 覆寫 Ext.ux.form.ItemSelector 的 setValue()
Ext.override(Ext.ux.form.ItemSelector, {
	setValue: function(values) {
		var index;
		var selectionsArray = [];
		this.toMultiselect.view.clearSelections();
		this.hiddenField.dom.value = '';
 
		if (!values || (values == '')) { return; }
 
		if (!Ext.isArray(values)) { values = values.split(this.delimiter); }
		for (var i=0; i<values.length; i++) {
			index = this.fromMultiselect.view.store.indexOf(this.fromMultiselect.view.store.query(this.fromMultiselect.valueField, new RegExp('^' + values[i] + '$', "i")).itemAt(0));
			if (index > -1) {
				selectionsArray.push(index);
			}
		}
 
		var records = [], record;
		if (selectionsArray.length > 0) {
			for (var i=0; i<selectionsArray.length; i++) {
				var record = this.fromMultiselect.view.store.getAt(selectionsArray[i]);
				records.push(record);
			}
			if(!this.allowDup)selectionsArray = [];
			for (var i=0; i<records.length; i++) {
				record = records[i];
				if(this.allowDup){
					var x=new Ext.data.Record();
					record.id=x.id;
					delete x;
					this.toMultiselect.view.store.add(record);
				}else{
					this.fromMultiselect.view.store.remove(record);
					this.toMultiselect.view.store.add(record);
					selectionsArray.push((this.toMultiselect.view.store.getCount() - 1));
				}
			}
		}
		this.toMultiselect.view.refresh();
		this.fromMultiselect.view.refresh();
		var si = this.toMultiselect.store.sortInfo;
		if(si){
			this.toMultiselect.store.sort(si.field, si.direction);
		}
		this.toMultiselect.view.select(selectionsArray);
	}
