iconFunction field for NavBar

So here is a work around. If you are binding a value object to the LinkBar you can specify a:

public function get icon():Class

function to return an icon based on data in the value object. It isn't ideal, but it works.

To me that seems wrong, like an omission<br />that someone accidentally overlooked. Does anyone have a workaround or know why<br />you can't specify an iconFunction like you can in other components? <br><br /><br><br />I went ahead and posted an issue in the bug system: <a<br />href="https://bugs.adobe.com/jira/browse/SDK-16296">https://bugs.adobe.com/jira/browse/SDK-16296</a><br />to see if that garnered any response. <br><br /><br><br />Sorry if this is the wrong place. The message is more for discussion about<br />adding the iconFunction to the NavBar class so the nav controls all can use it.<br /><o:p></o:p></span></font></p><br /><br /><div class=MsoNormal><font size=3 face="Times New Roman"><span<br />style='font-size:12.0pt'><br /><br /><hr size=2 width=200 style='width:150.0pt' align=left><br /><br /></span></font></div><br /><br /><p class=MsoNormal style='margin-bottom:12.0pt'><font size=3<br />face="Times New Roman"><span style='font-size:12.0pt'>View/reply at <a<br />href="http://www.adobeforums.com/webx?13@@.59b5fdd5">iconFunction field for<br />NavBar</a><br><br />Replies by email are OK.<br><br />Use the <a<br />href="http://www.adobeforums.com/webx?280@@.59b5fdd5!folder=.3c060fa3">unsubscribe</a><br />form to cancel your email subscription.<o:p></o:p></span></font></p><br /><br /></div>
