I have a JSON service array tied to a grid, with in the grid I have a Select component. The service response has two set of arrays. The first array sends a list of titles for the next array which sends the results for each title. Below is an example of what the array would return. I have the first array setup to the grid, and the second array setup to the Select component. It works fine, I get 5 different select fields with all the correct results. But I want to only show Category and hide the rest of the results. Can this be done?

Hi John,

To modify your service response you need to use "generic security context" and use it with your service.

1 Create custom security context service http://docs.appery.io/documentation/g...

2 Use next code to wrap answer and make custom logic (including server requests).
pre

Appery.MySecurityGeneric = Appery.createClass(SecurityContext, {

 invoke: function(service, settings) { 
     var oldSuccess = settings.success; 

     var onSuccess = function(value, other){ 

         //here you need to change your response stored in the value. 
         //value.hello = "world"//That's an example. 
         //To see what stored in the value variable please use following code: 
         console.log("value = "); 
         console.log(value); 

         oldSuccess.call(this, value, other); 
     }; 

     settings.success = onSuccess; 
     Appery.MySecurityGeneric.$super.invoke.call(this, service, settings); 
 } 

});
/pre
Note: you should replace "MySecurityGeneric" with your security generic context name.

1. After you create generic security context please use this context in your service.
