    <p>When you're using Worklight Adapter to call DP MPGW, the sequence as below <br/> <strong>Request</strong>: <br/> WL Client App --> WL Server (Adapter) --> DP MPGW<br/> <strong>Response</strong>: <br/> DP MPGW --> WL Server (Adapter) --> WL Client App<br/></p> <p>NOTE: The session id before/after WL server (Adapter) is not the same. If you want to do SSO, you need to pass your LTPA token in adapter to the backend DP. Here's the sample code for you.<br/></p> <p>Step1. Get LTPA token method (in you ChallengeHandler.js file)</p> <pre><code>sampleAppRealmChallengeHandler.isCustomResponse = function(response) { if (!response || response.responseText === null) { return false; } var indicatorIdx = response.responseText.search('j_security_check'); if (indicatorIdx &gt;= 0){ return true; }else if(response &amp;&amp; (response.responseJSON) &amp;&amp; (response.responseJSON['WL-Authentication-Success']) &amp;&amp; (response.responseJSON['WL-Authentication-Success']['WASLTPARealm'])){ // set ltpaToken when login success var realm = response.responseJSON['WL-Authentication-Success']['WASLTPARealm']; ltpaToken = realm.attributes.LtpaToken; console.log('Get ltpa token success: '+ltpaToken); } return false; </code></pre> <p>};</p> <p>Step2. Call procedure method (in client App js file)<br/></p> <pre><code>// define global LTPA token variable var ltpaToken = null; function getAccountInfo(){ // check ltpa token is not null, or get the ltap token from login user in WASLTPARealm if(!ltpaToken){ if(WL.Client.isUserAuthenticated('WASLTPARealm')){ var attrs = WL.Client.getUserInfo('WASLTPARealm', 'attributes'); if(attrs){ ltpaToken = attrs.LtpaToken; console.log('Set ltpaToken again: '+ltpaToken); } } } // Pass LTPA token from client App to WL server(adapter) var token = {'LtpaToken2' : ltpaToken}; var invocationData = { adapter: "DummyAdapter", procedure: "getAccountInfo", parameters: [token] }; WL.Client.invokeProcedure(invocationData, { onSuccess: getSecretData_Callback, onFailure: getSecretData_Callback }); </code></pre> <p>}</p> <p>Step3. Pass LTPA token to backend DP in adapter</p> <pre><code>function getServices( token) { path = getPath("path/to/services"); var input = { method : 'post', returnedContentType : 'json', path : path, cookies: token }; return WL.Server.invokeHttp(input); </code></pre> <p>}</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.
