    <p>I am trying to go through this sample <a href="https://github.com/blackberry/BB10-WebWorks-Samples/blob/master/Twitter-OAuth-1/README.md" rel="nofollow">https://github.com/blackberry/BB10-WebWorks-Samples/blob/master/Twitter-OAuth-1/README.md</a> </p> <p>Although, I keep getting the following error: Error in getAuthorization: ReferenceError:Can't find variable: facebookOptions</p> <p>Here is my code for my javascript OAuth.js </p> <hr> <pre><code>function initApp() { try { // facebook oauth setup facebookOptions = { clientId: '############', clientSecret: '######################', // we use a php script on a server because facebook doesn't allow for local:/// callbacks // at this time. the php simply redirects us back to 'local:///index.html' redirectUri: 'http://###########.com/redirect.php' }; // here we check for query strings in window.location when the app loads. This is because facebook is calling back // to our callbackUrl. When the app initializes, and there is a query string, it checks if the user // authorized the app or not var query = window.location.search; authCode = null; authCode = query.split('code='); authCode = authCode[1] || null; // we've got an auth code, let's exchange that for an access token if (authCode !== null) { getAccessToken(); } } catch (e) { alert('Error in initApp: ' + e); } } // first, we get the user to authorize with the service and allow our app access function getAuthorization() { try { showMessage('Contacting Facebook...'); window.location.replace('https://www.facebook.com/dialog/oauth?client_id=' + facebookOptions.clientId + '&amp;redirect_uri=' + facebookOptions.redirectUri + '&amp;scope=publish_stream,read_stream'); } catch (e) { alert('Error in getAuthorization: ' + e); } } // exchange our 'access code' for an 'access_token' function getAccessToken() { try { var url = 'https://graph.facebook.com/oauth/access_token?client_id=' + facebookOptions.clientId + '&amp;redirect_uri=' + facebookOptions.redirectUri + '&amp;client_secret=' + facebookOptions.clientSecret + '&amp;code=' + authCode; $.ajax({ type: 'GET', url: url, success: function(data) { var response = data; // parse 'access_token' from the response response = response.split('&amp;'); accessToken = response[0].split('='); accessToken = accessToken[1]; // get authenticated users' info for future use getUserInfo(); }, error: function(data) { alert('Error getting access_token: ' + data.responseText); return false; } }); } catch (e) { alert('Error in getAccessToken: ' + e); } } // get users info (we're grabbing their full name for this sample) function getUserInfo() { try { var url = 'https://graph.facebook.com/me?access_token=' + accessToken; $.ajax({ type: 'GET', url: url, dataType: 'json', success: function(data) { // data.name = users full name showMessage('Hello ' + data.name + '!'); $('#buttonSetup').hide(); $('#afterAuth').show(); }, error: function(data) { alert('Error getting users info: ' + data.responseText); return false; } }); } catch (e) { alert('Error in getUserInfo: ' + e); } } // update the users status function postToService() { try { var status = $('#inputBox').val(); if (status === '' || status === 'enter your status...') { showMessage('You didn\'t enter anything to post :('); return false; } else { showMessage('Updating status...'); var url = 'https://graph.facebook.com/me/feed?message=' + status + '&amp;access_token=' + accessToken; $.ajax({ type: 'POST', url: url, dataType: 'json', success: function(data) { showMessage('Status updated!!'); $('#inputBox').val('enter your status...'); // display the updated news feed to the user setTimeout(function() { getFeed(); }, 200); }, error: function(data) { alert('Error updating status: ' + data.responseText); return false; } }); } } catch (e) { alert('Error in postToService: ' + e); } } // get users news feed function getFeed() { try { showMessage('Getting news feed...'); var url = 'https://graph.facebook.com/me/feed?access_token=' + accessToken; $.ajax({ type: 'GET', url: url, dataType: 'json', success: function(data) { showMessage('Your news feed...'); var feed = data.data; // clear the content div, and prepare to add new data to it $('#content p').remove(); // show the last 4 items from the users news feed // note: there are several objects that could be posted in a news feed. for simplicity // we're only showing objects with a 'story' attribute for (var i = 0; $('#content p').size() &lt; 4; i++) { if (typeof feed[i].story !== 'undefined') { $('#content').append('&lt;p&gt;' + feed[i].story + '&lt;/p&gt;'); } } // display the feed, after it's been parsed $('#content').fadeIn(); }, error: function(data) { alert('Error loading news feed: ' + data.responseText); return false; } }); } catch (e) { alert('Error in getFeed: ' + e); } } // helper function for displaying a message to the user function showMessage(msg) { try { if (!$('#message').is(':visible')) { $('#message').show(); } setTimeout(function() { $('#message').html(msg); }, 500); setTimeout(function() { $('#message').fadeOut(500, function() { $('#message').html(''); }); }, 8000); } catch (e) { alert('Error in showMessage: ' + e); } } </code></pre> <hr> <p>the php redirect file on my web server is this:</p> <pre><code>&lt;?php $queryString = $_SERVER['QUERY_STRING']; header("location: local:///index.html" . $queryString); ?&gt; </code></pre> <p>I am not sure whether the problem is with the authorization in oauth.js or in the local redirect php file.</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
