If you're writing an app with multiple components, you need a clear
understanding of how each component will reference the others. For
example, if you write
<Application>
<SearchView id="searchView"/>
...
</Application>
then in the Application script you can refer to searchView to get the
SearchView instance and in the SearchView script you can refer to
parentDocument or application to get the Application instance.
If your searchView script has code like
private var filter:SearchViewFilter;
private someMethod():void
{
...
filter = new SearchViewFilter();
...
}
then your searchView can access the SearchViewFilter instance as
'filter'. However, you don't have a back reference from the
SearchViewFilter instance to the SearchView unless you do somethign like
pass 'this' in the constructor and store it.

Subject: Re: [flexcoders] newbie
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 func! tion 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.
