    <p>I am writing a flex3 tool for our uber-geeks. The tool is for futzing around with sharing URLs to various various social sites. </p> <pre><code>private function submitRequest(evt:Event):void { var requestURL:URLRequest = new URLRequest(constructURL()); requestURL.method=URLRequestMethod.POST; var header:URLRequestHeader = new URLRequestHeader("og:title", "petertitle"); requestURL.requestHeaders.push(header); navigateToURL(requestURL,"_blank"); } </code></pre> <p>I want allow the developer to manipulate the following meta headers in the outgoing html request when navigateToURL() is called.</p> <pre><code>&lt;meta property="og:title" content=title" /&gt; &lt;meta property="og:description" content="description" /&gt;\ &lt;meta property="og:image" content="......" /&gt; &lt;meta property="og:video" content="......"/&gt; &lt;meta property="og:video:height" content="640" /&gt; &lt;meta property="og:video:width" content="480" /&gt; </code></pre> <p>Unfortunately google is not showing me any example of how to add the above meta headers to my instance of URLRequest in flex. AND the new URLRequestHeader is blowing up.</p> <pre><code>ArgumentError: Error #2096: The HTTP request header og:title cannot be set via ActionScript. at global/flash.net::navigateToURL() </code></pre> <p>Can someone point me at an example of putting the meta headers into a URLRequest?</p> <hr> <hr> <p>additional</p> <p>Looks like I am in a catch 22 situation. I wrote the app to run in a flash player.</p> <ol> <li>apparently the flash apps run from flashbuilder are not permitted to perfom http PUT method operations. it alwasy does GET</li> <li>flash apps run from flashbuilder will not write headers on http GET calls.</li> </ol> <p>But I am still not finding a way to add an http "meta" header tag in flex... perhaps adobe air.</p> <p>Current work around.</p> <p>I can call an external javascript function that will do a post, but however the XmlHttpRequest infrastructure only want to setRequestHeader(key,value), and seems to need to be from a very specific list of strings. setRequestHeader("foo","bar") did not add a foo header in my outgoing request.</p> <p>There does not seem to be a way to add the header meta tag. via javascript. Or at lease I am not finding it off of google.</p> <p>Hoping someone can now point me at how to do that?????</p>

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.
