Hi Michel,
i had a similar problem and found a workaround. I have a class where two
separate areas (panels) should be allowed to be used in a subclass by using the
designer. In  general this the window structure of the superclass
    this (BorderLayout)
        cTopPanel (North, BorderLayout)
        cCenterPanel(Center, BorderLayout)

It might not be the most elegant piece of code, but it worked for me:

1. I ensured that my superclass used a BorderLayout. That is important since the

designer extracts this information when designing the subclass.
2. A variable "boolean cInitialized = false" is included.
3. In the default constructor I added "cInitialized = true" after the jbinit()
call.
4. I added the method
    public void add(Object pComp, Object pConstraints)
    {
        if (!cInitialized)
        {
            super.add(pComp,pConstraints);
            return;
        }
        if (pConstraints.equals(BorderLayout.NORTH))
            cTopPanel.add(pComp,BorderLayout.CENTER);
        else
            cCenterPanel.add(pComp,BorderLayout.CENTER);
    }

(I didn't checked for syntax here. It is just to give the general idea)

This is enough to persuade JBuilder to let the subclass be designed.

Best regards, Klaus
