ListField font update takes effect only when user scrolls

Question

I am developing an application which shows some user details on a screen. I use a custom ListField as suggested by the StackOverflow question "How to customize list field in blackberry?"

I am trying to appaly a font to each list field element, and it works well. But when I try to give 2 different fonts for two listfields, the font is only changed when I scroll on the screen. Does anyone have an idea how to resolve it?

field = getField(1);
layoutChild(field, 200, fontHeight + 1);
setPositionChild(field, preferredWidth-preferredWidth/3, 3);
setFont(fontForAllElements); 
Font fontForAllElements = Font.getDefault();
fontForAllElements = fontForAllElements.derive(Font.PLAIN, 16);

If scrolling fixes your problem, perhaps calling ListField.invalidate() will do the redrawing you need.
