Bug 37277 Title Area Dialog requires navigation to the error message
2.1 it is currently not possible to navigate to an error message. Sceen reader users need to use the JAWS cursor to find the error message and continue. We should 1) Make the label navigable 2) Make the label the next element in the tab order after the next button (we may get this for free).

/**

private void setImageLabelVisible(boolean visible){
	messageImageLabel.setVisible(visible);
	bottomFillerLabel.setVisible(visible);
	leftFillerLabel.setVisible(visible);
	
}
/**
 * Set the message backgrounds to be the error or normal color
 * depending on whether or not showingError is true.

private void setMessageBackgrounds(boolean showingError){
	
	Color color;
	if(showingError)
		color = errorMsgAreaBackground;
	else
		color = normalMsgAreaBackground;
		
	messageLabel.setBackground(color);
	messageImageLabel.setBackground(color);
	bottomFillerLabel.setBackground(color);
	leftFillerLabel.setBackground(color);
