JESS: Problem with Input Router?

[Bang Bui]

Hello

This is my problem:

I have a rule:  (defrule Rule1 => (printout t "Enter a number")  (readline t))

I want "Enter a number" is printed in a TextArea and input a number in a TextField. I set the TextArea is the output router and TextField is the input router. When I run my program, "Enter a number" was displayed in the TextArea but my program was locked. I couldn't input anything into the TextField.

Please help me.

I'm so sorry for my English.

 

Thanks a lot! 

 

Here is apart of my program.

public class frmExample1 extends javax.swing.JFrame
{
    Rete engine;
    TextReader tr;
    TextAreaWriter taw;
    public frmExample1()
   {
        initComponents();
        engine=new Rete();
        taw=new TextAreaWriter(taQuestion);
       //taQuestion is a TextArea
        engine.addOutputRouter("t", taw);
        engine.addOutputRouter("WSTDOUT", taw);
        engine.addOutputRouter("WSTDERR", taw);
        tr=new TextReader(false);
        engine.addInputRouter("t", tr, true);
        engine.addInputRouter("WSTDIN", tr, true);
        try
        {
            engine.eval("(defrule Rule1 => (printout t 'Enter a number')(readline t))");
        }catch(Exception e){System.out.println(e.toString());}
        engine.reset();
        engine.run();
    }
    private void txtAnswerActionPerformed(java.awt.event.ActionEvent evt)
   {                                           
         tr.appendText(txtAnswer.getText() + "\n");
         txtAnswer.setText("");
         //txtAnswer is a TextField
   }
}

How does "txtAnswerActionPerformed" get called? Is there a real  
actionPerformed() method somewhere that calls it?

You're running the whole application inside the JFrame's consructor;  
thinking about it, this would probably work, but it's highly unusual.  
Normally, we let constructors complete rather than invoking a long-
running process from them.

When you create
