Query regarding tables in adf

Question

Hi,
I am new to ADF.Last day I was experimenting with ADF tables.I've created an entity and a view object.I have also created an application module.I've written a custom method in application module which returns all the rows for a view.Then ,I created a JSF page and I dragged a read only table and created a button by dragging and dropping the custom method from the data control onto the page.But whenever the page is loading, before I even hit my button, the data is being displayed in the table automatically.I want to display the data in the table only after the button is hit.Is it possible in oracle ADF 11g?
Thanks in advance

Hi,
oracle.jbo.server.ViewObjectImpl has a method "executeEmptyRowSet" ("executeEmptyRowSet() method performs the logical equivalent of executing your view object with a predicate like "WHERE 1 = 2" (always false) in a more efficient way").
You create the view object class for your view object and expose the executeEmptyRowSet as client interface. And if you use a taskflow for example you can use this method as the default activity (via drag-n-drop).
VO-class:
public class TestVOImpl extends ViewObjectImpl {
     * This is the default constructor (do not remove).
    public TestVOImpl() {
    @Override
    public void executeEmptyRowSet() {
        super.executeEmptyRowSet();
}Best regards
