    copied!<p>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.</p> <p><strong>footer.mxml</strong></p> <pre><code>&lt;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"&gt; &lt;fx:Declarations&gt; &lt;!-- Place non-visual elements (e.g., services, value objects) here --&gt; &lt;mx:CurrencyFormatter id="currencyFormatter" currencySymbol="$" useThousandsSeparator="true" precision="2" /&gt; &lt;/fx:Declarations&gt; &lt;fx:Script&gt; &lt;![CDATA[ [Bindable] public var cartValue:int; ]]&gt; &lt;/fx:Script&gt; &lt;s:HGroup width="100%" contentBackgroundColor="#000000" paddingBottom="0" paddingLeft="0" paddingRight="0" paddingTop="0"&gt; &lt;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')"/&gt; &lt;s:Button x="121" y="624.5" width="25%" height="64" label="Orders" chromeColor="#2259AA" fontSize="10" icon="@Embed('assets/doc_lines_stright.png')"/&gt; &lt;s:Button x="241" y="624.5" width="25%" height="64" label="Help" chromeColor="#2259AA" fontSize="10" icon="@Embed('assets/spechbubble.png')"/&gt; &lt;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')"/&gt; &lt;/s:HGroup&gt; &lt;/s:Group&gt; </code></pre> <p><strong>RincoTest.mxml</strong></p> <pre><code> &lt;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" &gt; &lt;fx:Style source="RincoTest.css"/&gt; &lt;fx:Declarations&gt; &lt;!-- Place non-visual elements (e.g., services, value objects) here --&gt; &lt;/fx:Declarations&gt; &lt;fx:Script&gt; &lt;![CDATA[ [Bindable] public var cartValue:int; ]]&gt; &lt;/fx:Script&gt; &lt;s:titleContent&gt; &lt;s:Image left="1" top="3" width="173" height="75" backgroundAlpha="1.0" smooth="true" source="assets/iphone_large.png"/&gt; &lt;/s:titleContent&gt; &lt;s:navigationContent&gt; &lt;mx:Spacer width="10" height="82"/&gt; &lt;/s:navigationContent&gt; &lt;/s:MobileApplication&gt; </code></pre> <p><strong>And this is how I am implementing it</strong></p> <pre><code>&lt;components:footer x="1.65" y="614.95" width="100%" height="64" cartValue="{cartValue}"/&gt; </code></pre> <p>I have tried to bind Application.application.cartValue and MobileApplication.application.cartValue. Neither of them work.</p> <p>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.</p> <p>Thanks, Ernie</p>
