Hi,
I have this part of code
[AS]
var _cb = _this.getChildByName(“group_cb”);
trace(“>> “+_cb)
var getGroupNum:int = _theBigArray.length/2;
var i:uint;
for (i=0;i<getGroupNum;i++) {
_cb.addItem({label: _theBigArray[i*2][1], data: i2});
trace("addItem [label: “+_theBigArray[i*2][1]+” data "+(i2)+”]”);
}
[/AS]
the output from trace is:
>> [object ComboBox]
addItem [label: Antique Photo Border data 0]
addItem [label: Red Photo Border data 2]
addItem [label: Blue Photo Border data 4]
But when I clicked to scroll combobox it appear this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Why is getting this errors?
