I am using Flash Builder 4 Burrito Preview - builing a Mobile Application. I have a custom component called footer.mxml. That footer has 4 buttons, and one of them has a lable that is bound to cartValue. I am trying to maintain a global variable called cartValue within all views and footer component. footer.mxml <pre><code><s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="100%" height="64" chromeColor="#000000" fontSize="10"> <fx:Declarations>  <mx:CurrencyFormatter id="currencyFormatter" currencySymbol="$" useThousandsSeparator="true" precision="2" /> </fx:Declarations> <fx:Script> <![CDATA[ [Bindable] public var cartValue:int; ]]> </fx:Script> <s:HGroup width="100%" contentBackgroundColor="#000000" paddingBottom="0" paddingLeft="0" paddingRight="0" paddingTop="0"> <s:Button x="0" y="624.5" width="25%" height="64" label="Account" chromeColor="#2259AA" enabled="true" fontSize="10" fontWeight="bold" icon="@Embed('assets/user.png')"/> <s:Button x="121" y="624.5" width="25%" height="64" label="Orders" chromeColor="#2259AA" fontSize="10" icon="@Embed('assets/doc_lines_stright.png')"/> <s:Button x="241" y="624.5" width="25%" height="64" label="Help" chromeColor="#2259AA" fontSize="10" icon="@Embed('assets/spechbubble.png')"/> <s:Button x="360" y="624.5" width="25%" height="64" label="{currencyFormatter.format(cartValue)}" chromeColor="#2259AA" fontSize="10" icon="@Embed('assets/shop_cart.png')"/> </s:HGroup> </s:Group> </code></pre> RincoTest.mxml <pre><code> <s:MobileApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" backgroundColor="#000000" firstView="views.RincoTestHome" > <fx:Style source="RincoTest.css"/> <fx:Declarations>  </fx:Declarations> <fx:Script> <![CDATA[ [Bindable] public var cartValue:int; ]]> </fx:Script> <s:titleContent> <s:Image left="1" top="3" width="173" height="75" backgroundAlpha="1.0" smooth="true" source="assets/iphone_large.png"/> </s:titleContent> <s:navigationContent> <mx:Spacer width="10" height="82"/> </s:navigationContent> </s:MobileApplication> </code></pre> And this is how I am implementing it <pre><code><components:footer x="1.65" y="614.95" width="100%" height="64" cartValue="{cartValue}"/> </code></pre> I have tried to bind Application.application.cartValue and MobileApplication.application.cartValue. Neither of them work. If there is a better way to maintain a cartValue across the entire application please let me know. This is my first attempt with Flex. Thanks, Ernie

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
