flex - Checking through an Object and returning if the element is found -

i trying return true items found within object although arrays within object have more 1 element within it. example selectedeventtypes[9] has array of [cancelled,cancelled2,cancelled3], although whenever item.eventtype cancelled2 never realise within object , return false this.

private function eventfilterfucntion(item:object):boolean {        if(selectedeventtypes.indexof(item.eventtype)>-1)     {         return true;     }     return false; } 

it looks have defined selectedeventtypes array of array like:

private var selectedeventtypes:array = [["a1", "a2"],         ["b1","b2"],         ["c1","c2"],         ["d1","d2"],         ["e1","e2"],         ["f1","f2"],         ["g1","g2"],         ["h1","h2"],         ["i1","i2"],         ["cancelled", "cancelled2", "cancelled3"],         ["received","last"]]; 

where

selectedeventtypes[9] = ["cancelled", "cancelled2", "cancelled3"] 

in case can change eventfilterfunction below:

private function eventfilterfucntion(item:object):boolean     {         each(var eacharray:array in selectedeventtypes)         {             if(eacharray.indexof(item.eventtype) > -1)             {                 return true;             }         }         return false;     }
