Need help in refreshing the wired app

If you want to change the second app so it doesnt display the proprty table until it receives data from the first app then one way to solve this is to extend the app javascript implementation. All the apps created using the App Maker wizard have the same underlying javascript implementation. 

Open the app in the App Editor. The App Spec should be displayed in the editor and teh drop down chocie should contain a single entry, App.xml.

Click the "Add" link, next to the drop down choice, and add a new javascript resource. Call it something like "extended-basic-app.js". Paste in the following code and save:

Sample.ExtendedBasicApp = function(app){
    var that = new Presto.BasicApp(app),
    basicReceive = that.receive,
    root = jQuery(app.getRootElement());

    that.receive = function(obj){
        root.show();
        basicReceive.call(that, obj);
    };
    root.hide();
    return that;
}

Update the App.xml to point to this new Constructor function, by replacing the jsclass attribute value in the root <app> tag, so the App spec should now contain:

<app ...... jsclass="Sample.ExtendedBasicApp".... >

and save again.

All this extended version of Presto.BasicApp does is hide the app when it is first rendered, getting hold of a reference to the app's root element and using the jQuery hide method. It then overrides the Presto.BasicApp receive method which is called each time a subscribed event is received, and it uses the jQuery show method to display the app. 

You could also use this extended version of Presto.BasicApp to filter events, for example, if you only wanted to refresh the PropertyView if teh url changes you could use something like:

    var previousUrl;
    that.receive = function(obj){
        if(obj.url != previousUrl){
           previousUrl = object.url;
           root.show();
           basicReceive.call(that, obj);
        }
    };

Hello Jeremy

Thanks for the reply and the great help. I am sure I would be able to get this working for me and I would be trying out the same as you have guided.

Mean while request you to please allow me permissions to access the example applications which you have created. My user id is nitish.kumar

Thanks Again

My mistake, I've changed the security settings on the apps so any logged in user can view. Let me know if you have any problems.
