[udig-devel] Udig trunk and printing

[Mauro Bartolomeoli]

Unfortunately not, but I found what was the problem. I had to change the 
getText method of LegendGraphic to this:

private String getText( Rule rule ) {
        String text = ""; //$NON-NLS-1$
        if (rule.getTitle()!=null && !"".equals(rule.getTitle())) { 
//$NON-NLS-1$
            text = rule.getTitle();
        } else if (rule.getTitle()!=null && !"".equals(rule.getName())) 
{ //$NON-NLS-1$
            text = rule.getName();
        } else if(rule.getFilter()!=null){
            text = rule.getFilter().toString();
        }
        if (text.length() > 19) {
            return text.substring(0, 18) + "..."; //$NON-NLS-1$
        } else {
            return text;
        }
    }

In short, title, name and filter were null, but the code was looking for 
empty strings, so a null value was assigned to text, bringing 
text.length() test to a NullPointerException.
