ADF Table didn't refresh after adding new rows from procedure

After calling a stored procedure(which adds new rows to a table) , table didn't refresh on programmatic partial trigger to show up the latest rows

Even re-executed the query did not works.

Looks like we need to clear the VO cache, before re-executing the query

Call AM Method from VORowImpl ADF

In an ExampleVORowImpl, we can overwrite the getters of the attributes to customize the return values, Here we see the count value appended with ' ( ' , ' ) '  and the count value is returned from the AM method

import com.fdny.example.model.service.ExampleAppModuleImpl;                                                      

Pass Parameter from JavaScript to a ManagedBean ADF

http://naive-amseth.blogspot.com/2011/02/passing-parameters-from-javascript-to.html
http://adfjavacodes.blogspot.com/2013/06/adf-calling-java-code-from-javascript.html

This sample code demonstartes how to pass a parameter to a backing bean method using JavaScript
   clientListener calls the javascript method
   serverListener is used to call the managed bean method
   (*serverListener is triggered only when AutoSubmit    or the partial submit property of the component is           enabled)

backing bean method:

This is the other way of passing parameter to backing bean

 In the clientListenerMethod of JavaScript var parameter is initialized here

sample JavaScript code to trigger the button

 function buttonListenerMethod() {
         //get a button and click it
         var proxyButton = AdfPage.PAGE.findComponentByAbsoluteId('cb1');
     
         var parameter = {city:"Manhattan", country:"US"};
         //click the button
         AdfCustomEvent.queue(proxyButton ,"customButtonEvent",parameter, true);
       }

or

One more good usecase where we can use ClientListener/ServerListener

View Object with Bind Variable as view accessor

Best practice tip:
A View Object with Bind Variable should be used with a View Criteria when used as view accessor to another object.

*This has to be done to void some weird SQLException errors with bind parameter :vctemp1  etc..

Contextual Events ADF

http://www.oracle.com/technetwork/issue-archive/2011/11-may/o31adf-352561.html

Check out the sample example application ContextualEventsApp code

Usecase:
Submit Button click triggers the region-consumertaskflow1 
Last Name Input text value change triggers the region-consumertaskflow2

• Run Producer.jspx page

                This page contains regions(consumertaskflow1 and consumertaskflow2) which are refreshed                   by some actions of the page using  contextual events

• consumertaskflow contains a page consumer.jsff which has EventHandler methods in its bindings

Methods handleEventStringPayload and handleEventObjectPayload accepts customPayLoad parameter.
