Title: Getting LookupTextField to work in ULC 6.1

Hi All

I'm struggling with getting the LookupTextField of the code community to work with ULC 6.1.

In order to get it compiling I had to change the following lines of UILookupTextField:
public void setForegroundColor(int red, int green, int blue, int alpha, boolean refresh)
{
    super.setForegroundColor(red, green, blue, alpha, refresh);
    fForeground = getTextComponent().getForeground();
}
To
public void setForegroundColor(Color inColor)
{
    super.setForegroundColor(inColor);
    fForeground = getTextComponent().getForeground();
}

Unfortunately if I try to start the ULCLookupTextFieldSample I'm getting the following error:
1 30.06.2006 10:45:38.377 1'000 SEVERE Thread[AWT-EventQueue-1,6,main] com.ulcjava.base.client.UISession b got exception while processing [java.lang.NullPointerException
