The simplest way is to:
(1) Create a custom method on your application module
(2) Publish that method on the application module's client interface
(3) Drop the custom method as a button onto your form.
When you click the button created in step 3, it invokes the code in your application module method automatically.
Assuming you are wanting to delete the current row from a view object instance named "EmpView" in your application module's data model, your method would look like this:
public void deleteCurrentEmpAndCommit() {
  Row empRow = getEmpView().getCurrentRow();
  if (empRow != null) {
    empRow.remove();
    getDBTransaction().commit();
}I believe you requested a pre-release of the ADF Developer's Guide for Forms/4GL Developers from me. The steps to create and publish custom methods on an application module are covered in sections:
8.3, "Adding a Custom Service Method"
8.4,"Publishing Custom Service Methods to Clients"
10.3.3, "How the Data Model and Service Methods Appear in the Data Control Palette"
