Need advice on application layout

[EvolvedDSM]

Some background info on the project. My application will be using a single
database table as it's data source, using Flex Data Services 2. This table
contains problem tickets that my users have given me. The table contains a
"status" column, which holds an 'open' or closed' value to denote the current
status of the problem ticket, as well as a date column to signify when the
ticket was submitted.

I need to make an application that will show three different views of the same
table: the current day's open tickets, the current day's closed tickets, and a
history of all tickets. I also need to include a form where I can input
tickets.
Here's an example I made in a few seconds of what I am thinking it would look
like:

This is where I need advising. Since all three datagrids will be using the
same data source, but will require a different filterFunction on the
dataprovider, is it better to separate each tab into a component where I can
create a single dataprovider with filterFunction for each grid, or keep it all
within the main application? If I separate them, how can I make sure each grid
will properly update when I add a new ticket, or change the status of a ticket?

Also, does anyone else have a better suggestion for my design?

If you bind you controls to the data model(s), and use the dataProvider AIP to
update the data, then the UI/data synchronization will happen automatically.

The filter function makes a copy of the data, leaving the base model alone.

Components are usually easier to maintain.

ntsiii can you elaborate on what an AIP is? Maybe I'm already using it and
just don't know what it is?

I was planning on declaring a dataservice with an arrayCollection of the data
to populate the grids (i'm using CF as my backend). To create new records I
was going to use a ds.createItem(item) statement. Updating the records would
be done through the datagrid edit property.

One question: If I'm creating separate components and declaring the same DS
and AC in each component but with different filters on the AC, will the DGs
update properly while the filter is on it? Or is there something I need to do,
like an addEventListener to get all the data to update properly?
