Body
copied!<p>I am trying to set selectedItem on a comboBox(mx). Following is the code :</p> <pre><code>callLater(function ():void { if (comboBox.dataProvider && comboBox.dataProvider.length > 0) { comboBox.selectedItem = comboBox.dataProvider.getItemAt(0); } }); </code></pre> <p>EDIT : I am creating Comboboxes programatically : </p> <pre><code>var comboBox:ComboBox = new ComboBox(); </code></pre> <p>This works fine and sets the selectedItem to the first item from the data provider - <strong>but ONLY if the combobox is displayed on the screen and not hidden within a collapsible group</strong>.</p> <p>I have a situation where I may have the combobox enclosed within a Collapsible Group (my own component) and not displayed until the collapsed group is expanded (see images below)</p> <p>First Image : When the groups are collapsed and combobox is not displayed but created <img src="https://i.imgur.com/g6RI0.png" alt="collapsed_groups"></p> <p>Second Image : when the collapsed group is expanded to display the combobox - notice that the first element in the dataprovider is NOT selected as selectedItem</p> <p><img src="https://i.imgur.com/8Dg5l.png" alt="Expanded Group"></p> <p>following line is ALWAYS executed</p> <pre><code> comboBox.selectedItem = comboBox.dataProvider.getItemAt(0); </code></pre> <p>But the first item is not selected in the case when the combobox is enclosed in a collapsed group - works fine when the combobox is enclosed in an expanded group.</p> <p>I think this is a bug in flex - unless someone thinks otherwise ?</p>
