Oracle Forms

Hello !

I am trying to create a PJC for a text item to automatically trim leading or trailing blank spaces. I thaught it was simple but when i try to enter the text "java" with a white space at the beginning each time I press the space bar I have an error message in the java console, the applet is dead .

here is my PJC code

import java.awt.Component;
import oracle.forms.handler.IHandler;
import oracle.forms.ui.VTextField;

public class TextTrim extends VTextField {
static IHandler mHandler;

public TextTrim() {
super();
}


public void init(IHandler handler)
{
super.init(handler);
mHandler = handler;
// put your initialisation instructions here
}

public String getText() {
return super.getText().trim();

}
}

I have this error
