URGENT: Opening JInternalFrame upon click of a button

Question

Hi can somebody help me, Im a newbie in JDeveloper IDE and have no proper training.
Im using Oracle Jdeveloper 10.1.3.3.0. My project is an ADF Swing Application.
Let me explain what I'm trying to do..
I like to open another JinternalFrame upon click of a button.
When I click the button. Im passing two parameters(bind variables) to filter the view object
of the class and displlay its result in JinternalFrame.
I have a ClassA that extends JinternalFrame, it contains components such as textbox, combo box etc. and a button labeled (Show ClassB).
I also have ClassB that extends JinternalFrame, its view object required two bind variables.
In ClassA, it has table and i will select one row and click on a button.
I will pass the value in the table to the bind variable of the view object of ClassB and open and display the result in JInternalFrame.
Im getting the parameters, but i cant pass it on the bind attribute of the view object.
How can I do this in my java class with the relation of its pagedef.
Im comfused..
Please help.
Thanks.

Hi,
independent of whether this is a internal frame or a
panel, you can use
OperationBinding oper = (OperationBinding)
panelBinding.get("ExecuteWithParams");
per.getParameterMap().put("ArgumentName1",argument1);
oper.getParameterMap().put("ArgumentName2",argument2);
oper.execute();>
assuming that the bind variables are exposed in th
epageDev file as a ExecuteWithParams operation
Hi Frank,
I have this code for the button
         private void jButton4_actionPerformed(ActionEvent e) {
              if (jTableLeft.getValueAt(jTableLeft.getSelectedRow(),0) != null) {
                   System.out.println("quot trans no" + 
                   jTableLeft.getValueAt(jTableLeft.getSelectedRow(),0).toString());
                  quotTransNo = new
                       Integer(jTableLeft.getValueAt(jTableLeft.getSelectedRow(),0).toString());
             PanelQuotations pq = new PanelQuotations();
             JUPanelBinding quotbinding = pq.getPanelBinding();
             System.out.println(quotbinding.getName());
             OperationBinding oper =
                      (OperationBinding)quotbinding.get("ExecuteWithParams");
             oper.getParamsMap().put("param_quotTransNo",quotTransNo);
             System.out.println("Bago na to");
             oper.execute();
            openQuotation();//opens new JInternalFrame          
    }When I testes it, it gave me a "Null Pointer Exception" in this line
oper.getParamsMap().put("param_quotTransNo",quotTransNo);
Why am I getting such error? I dont know why?
Thanks.
