Clearing VO after the search in ADF C, JSP

Question

How do you clear a where clause of a VO after searched for a record. I have VO using more than one table. As soon as you open the view it shows all the records. I have Find and Execute buttons to search for specific records in the table. This works fine. But if there no records for the Find, I want to reset the VO to show all the records. How do you do that? Thanks.

Maybe this can work:
1. Add a public method to your Application Module (right click on AM and go to Application Module Class) - example:
public void showDetail(){
ViewObject vo = (SearchDynamicViewImpl)findViewObject("SearchDynamicView1");
String s_where = "ID = 100";
vo.setWhereClause(s_where);
vo.executeQuery();
2. Use avaliable VO methods to programmatically control the View Object (i.e., see clearcache() method):

3. Drag and drop the AM Method onto your page and select Command Button - will end up with code on .jspx page like this to call AM Method:
<af:commandButton actionListener="#{bindings.showDetail.execute}"
text="showDetail"
disabled="#{!bindings.showDetail.enabled}"/>
I have not done this before but if I thought these references may help.
