I was beating on this combobox/datagrid thingy and was able to have a
measure of success by using the same arraycollection ..
BUT, this will populate the dropdown with duplicate entries. I was
trying to figure a way around this with flex array manipulation but I
just couldnt get it.
Searching around I found this little gem, but I admit extending the
array with a prototype function in flex is a bit over my melon at the mo..
Array.prototype.removeDuplicates = function(fn,matchFN) { // removes
duplicate items from an array and returns a new array
var a = ([]).concat(this);
(fn==null) ? a.sort() : a.sort(fn);
if (matchFN!=null) {
for (i in a) if (matchFN(a[i],a[i-1])) a.splice(i,1);
} else {
for (i in a) if (a[i]==a[i-1]) a.splice(i,1);
}
return a;
}
Now is this really something I need to deal with, or shouldnt flex be
all snazzy with some neat array manipulation that I just dont seem to see?
If it is something I need to add, is there any advice about extending
existing flex functions.
