    <p>I have an XML that i retrieve from a call so all values are dynamic exept for the labels of the nodes(so I know that there is a appname that I have to display). I display appname in a ComboBox, then I need to get another value from another label in the same node, my xml has structure like so </p> <pre><code>&lt;root&gt; &lt;item&gt; &lt;name&gt;Hello&lt;/name&gt; &lt;version&gt;World&lt;/version&gt; &lt;/item&gt; &lt;item&gt; &lt;name&gt;See_you&lt;/name&gt; &lt;version&gt;soon&lt;/version&gt; &lt;/item&gt; &lt;/root&gt; </code></pre> <p>Now, I have a flex mx:ComboBox that has dynamic values, the user selects the label , for example Hello, and I need to find the corresponding node value, and the child value, so i can return World. </p> <p>I can define the labels of the ComboBox via dataProvider, so it's done. Now I cannot get the selected value via trace(event.currentTarget.selectedItem.@label); (I have on change handler on the ComboBox) = that's 1 problem;</p> <p>Second problem is how can I get a node value from an xml object if I have another node value in the same parent node( in this case)?</p> <p>I'm stuck on this and running out of time, please help. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ i have it like this in my mxml </p> <pre><code>&lt;mx:AddChild relativeTo="{VGroup}"&gt; &lt;mx:ComboBox id="AppListBox" change="AppListBox_changeHandler(Event.CHANGE)"/&gt; &lt;/mx:AddChild&gt; </code></pre> <p>then i provide data, when I have it in my script, like so</p> <pre><code>AppListBox.dataProvider = appxml.item.appname.text(); </code></pre> <p>appxml - is a that xml</p> <p>Then I try to get the value of selected item, i tried like that:</p> <pre><code>protected function AppListBox_changeHandler(event:Event):void { trace(event.currentTarget.selectedItem.label); trace(event.currentTarget.selectedItem.data); trace(event.currentTarget.selectedItem.@label); trace(AppListBox.selectedItem.label); trace(AppListBox.selectedItem.@label); trace(AppListBox.selectedItem.name); </code></pre> <p>it does not display anything. not even error</p>

    1. COFor the ComboBox dataprovider you can supply the list of item objects which means each selectedItem will have a .@name and a .@version then you can set labelField on the ComboBox to @name, in your change handler the comboBox.selectedItem.@version will have the corresponding value. If you don't follow please post your ComboBox code and the part that shows how the DP is provided to the combo box.

    3. COtry trace("Some literal in your change handler"); to be sure it's hitting the handler and that the console is outputting values and it's just the case that all of those are somehow blank... which I find hard to believe, some of those should cause errors.

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.
