Thank you. will do that and see what happens.

working without the event and custom event object. I think you need to have a

I am sorry but I am slow. By applying the filter in the main instance
variable, are you suggesting that I put it somewhere within this function?
private function accommodationLocatorResultHandler(event:ResultEvent):void
{
var lodgings:ArrayCollection =
event.result.accommodations.accommodation;
var temp:ArrayCollection = new ArrayCollection();
var cursor:IViewCursor = lodgings.createCursor();
var filter:AccommodationFilter = new AccommodationFilter();
while (!cursor.afterLast)
{
var accommodation:Accommodation = new Accommodation();
accommodation.fill(cursor.current);
temp.addItem(accommodation);
cursor.moveNext();
}
accommodations = temp;
}

Call it in the result handler.
Either apply the filter to the main instance level variable
“accomodations”, or do as you have and then assign selectedAccoms to the
dataGrid dataProvider.

This is the function I thought of introducing. I didn't introduce
it because I couldn't really work out how it would be called if I wanted data
to be updated automatically i.e. without a button click or something like that.
[Bindable]
private var selectedAccoms:ArrayCollection;
public function updateGrid():void
{
selectedAccoms = new ArrayCollection(accommodations);
//selectedAccoms.filterFunction =;
selectedAccoms.refresh();
dgAccom.dataProvider = selectedAccoms;
}

Does your handler get called? Does it contain the reference you
need? How are you applying the filter? Are you calling refresh()?

Main

//sending data methods using httpservice to say var accommodations

private function dispatchFilter():void

var event:FilterEvent =
new FilterEvent(filter, checked); //filter hold values of
selection of chk1 & chk2
dispatchEvent(event);
}
filterEvent.as comstructor
public function FilterEvent(filter:MyFilter, live:Boolean)
{
super(FILTER);
this.filter = filter;
this.live = live;
}
MyFilter.as
public function accept(accommodation:Accommodation):Boolean
{
if (graded && !accommodation.graded)
return false;
if (backpacker && !accommodation.backpacker)
return false;
return true;
}
Above is my abbreviated code. I think my problem is that I am unsure
about how to get the result data after filtering. In my mind the filtering
function is working on the data retrieved using httpservice.......but I havent
actually cracked that part well...at one point I thought of introducing a
function for capturing selected data.....

I have two pages. The first is the main. In the main I load my
xml data as follows using Httpservice. I pass this data to the second page as
follows:
<SearchView id="searchView" label="Search" accommodations="{accoms}"
/>
// accommodations has been declared publicly in SearchView.mxml and
accoms is the variable that was used to accept data sent by httpservice. Once
the data is passed, I display in the datagrid. All is fine at this stage.
My second step was to attempt to filter the data in the datagrid and
this is where my trouble began. I have two actionscript files one is for
carrying out the filtering and the other is for the filterEvent. oh by the way
there is yet another actionscript file which is essentially the class file for
accommodations. At this point, the following sequence of events can take place:
a click on a checkbox calls a function dispatchFilter
the dispatch filter creates an instance of class filterevent and dispatches
the event
the dispatched event takes as its parameter instance of the filter class and
thus reviews what has been checked or unchecked..
I tried using a get function but a while I realised that I miss
something relating to passing data between components.

Be specific, and try one part at a time.
What have your tried ? Why didn't it work ?
