You need an associative array. You won't need to check for duplicates that way -- its built into the datatype.
http://livedocs.macromedia.com/labs/1/flex20beta3/00001584.html var myArray:Array = new Array(); var testArray1:Array = [{Classname:"class 10",data:1},{Classname:"class 10",data:1}]; var testArray2:Array = [{Classname:"class 10",data:2},{Classname:"class 10",data:2}]; myArray[testArray1] = testArray1; myArray[testArray2] = testArray2; myArray[testArray1] = testArray1; myArray[testArray2] = testArray2; myArray[testArray1] = testArray1; myArray[testArray2] = testArray2; myArray[testArray1] = testArray1; myArray[testArray2] = testArray2; myArray[testArray1] = testArray1; myArray[testArray2] = testArray2; Even after all that, myArray still only contains two elements. make sense? it is early and I'm not the best at explaining things at this hour. ekokurtz wrote: > I'm trying to figure out the syntax to check for the existence of a > value in an array (that's inside an array collection) to see if I > need to add a new entry or ignore (to get an array of unique > entries).
