The problem of getting focus when using JPanel as a JTable cell editor

Question

I have a cell editor containing a small button that can be double-clicked to open the edit dialog, and then a text field that can be used to edit the built-in value (a popup is required to edit additional values, only the first is shown in JTable).

When the user clicks on the field, everything is fine, but if they are inserted into the field, the text field does not receive focus, and they cannot edit the field if they do not click on it with the mouse.

I tried to mess around with various jpanel focus methods, but it didn't matter, does anyone know what I'm doing wrong?

import com.jthink.jaikoz.guielement.Focus;
import com.jthink.jaikoz.table.CellLocation;

import javax.swing.*;

import java.awt.event.ActionListener;
import java.util.ArrayList;

public class SimpleMultiRowCellEditor
    extends DefaultCellEditor implements ActionListener
{

    final JPanel panel;
    private final DatasheetToggleButton rowCount;
    Cell value;

    public SimpleMultiRowCellEditor(final JTextField text)
    {
        super(text);
        this.setClickCountToStart(1);

        rowCount = new DatasheetToggleButton();
        rowCount.setVisible(true);
        rowCount.addActionListener(this);
        panel = new JPanel();
        panel.setOpaque(false);
        panel.setLayout(new BoxLayout(panel, BoxLayout.X_AXIS));
        panel.add(rowCount);
        panel.add(editorComponent);
        /*panel.setFocusable(true);
        panel.setFocusCycleRoot(true);
        ArrayList focusOrder = new ArrayList();
        focusOrder.add(editorComponent);
        focusOrder.add(rowCount);
        focusOrder.add(panel);
        panel.setFocusTraversalPolicy(new Focus(focusOrder));
        */
    }

    public Component getTableCellEditorComponent(
        final JTable table, final Object val, final boolean isSelected,
        final int row, final int column)
    {
        value = (Cell) ((Cell) val).clone();
        rowCount.setText(String.valueOf(value.getValues().size()));
        delegate.setValue(value.getValue());
        return panel;
    }

    public Object getCellEditorValue()
    {
        final String s = (String) delegate.getCellEditorValue();
        value.setValue(s);
        return value;
    }

    public void actionPerformed(final ActionEvent e)
    {
        this.stopCellEditing();
        final CellLocation cl =  Datasheet.getActiveEditSheet()
            .getTable().getSelectedCellLocations().get(0);
        UpdateMultiRowCellDialog.getInstanceOf().display(value,cl);
    }
}

Tried to add a magician to the panel, it seemed to have no meaning

class PanelFocusListener implements FocusListener
{
    public void focusGained(FocusEvent e)
    {
        System.out.println("Gained Focus");
        editorComponent.requestFocusInWindow();
    }

    public void focusLost(FocusEvent e)
    {
        System.out.println("Lost Focus");

    }
}
