Overriding Commit action does not work

Question

Hello
I am using Jdeveloper 10g (9.0.5.1), and created a simple uix input form with Create and Commit operation buttons. It works very nicely.
However, I am trying to override the Commit action because i would like to present a confirmation message for the commit process.
I followed the Online help to override Commit action as f
1- Changed the event property from 'action' to 'Commit'
2- right click the datapage and selected "Go to Code"
3- inside the DataAction Class i wrote the following
public void onCommit(DataActionContext ctx)
System.out.println("test override commit");
if (ctx.getEventActionBinding() != null) ctx.getEventActionBinding().doIt();
When i run the sample and add a new record, then press the Commit button, The function onCommit is called and the System.out.println is executed however, the Commit operation does not seem to work and the commit button is still enabled, no changes are seen in the database. When the commit is pressed one more time, the commit seems to work fine.
I repeated the procedure over and over again, still no result
I believe that overriding action buttons is important for developing non-trivial Web Applications. I appreciate any response
thanks

I am not sure why you used this method to get your application module:
svc = (ApplicationModule)ctx.getBindingContext().findDataControl("ApplicationModuleDataControl").getDataProvider();
Does your code get something different than doing it this way:
ctx.getBindingContainer().getApplicationModule()
The following scenario did not work because it did not pick up the values from the messageLovInput and the 2 messageTextInput fields. The fields are in the DataActionContext request object but they don't get written to the database, so I had to add the setAttribute methods in order to attempt to get it to work but there are still other problems that have arisen doing it this way (i.e. can't get the new dbsequence id for additional inserts into another table within the onCommit).
1. Drag and drop a Commit button on the page.
2. In the action I put the following code:
public void onCommit(DataActionContext ctx){
// Do validation here
//In order to get the data in the database, I had to add the following 5 lines of code:
ViewObject vo = ctx.getBindingContainer().getApplicationModule().findViewObject("NetView1");
Row row = vo.getCurrentRow();
row.setAttribute("NetId",ctx.getBindingContainer().getHttpServletRequest().getParameter("VB_NetId"));
row.setAttribute("PermittedCount",ctx.getBindingContainer().getHttpServletRequest().getParameter("VB_PermittedCount"));
row.setAttribute("Frequency",ctx.getBindingContainer().getHttpServletRequest().getParameter("VB_Frequency"));
//Commit
ctx.getBindingContainer().getApplicationModule().getTransaction().commit();
}I don't think it should be this difficult to get the onCommit event to work.
