Unable to find JGoTextEdit .getComponent

New to Jgo, While trying to override JGoText.doStartEdit as following, compile error because JGoTextEdit.getComponent is undefined. Do I miss something or this is no longer supported?
public void doStartEdit(JGoView view, Point vc) {
super.doStartEdit(view, vc);
JGoTextEdit edit = view.getEditControl();
if (edit != null) {
JComponent comp = edit.getComponent(view);
if (comp != null && comp instanceof JTextField) {
JTextField jtext = (JTextField)comp;

I don’t understand how you could get such a compile error, since com.nwoods.jgo.JGoTextEdit extends JComponent, which defines getComponent.

JGoTextEdit defines a getTextComponent method too, and that uses getComponent.
I am using 5.21 Jgo for SWT, and in com.nwoods.jgo.JGoTextEdit
JGoTextEdit extends from JGoControl, and JGoControl extends from JGoObject. I don't see how it is related to JComponent, and don't see getTextComponent method as well.
Confused ....

Oops, I typed the wrong thing. I meant what you said.

The problem is that I didn't know you were talking about SWT.
JGoControl.getControl is the method equivalent to getComponent in the Swing version. There isn't a getTextComponent -- that method is Swing-specific too.
