[elyes sallem]

Hello,
i use a property in a jsp , "shortcomment" , which depend of another
property, "CAjustComment":

    public String getShortcomment() {
        if (CAjustComment.length()>15)
            return CAjustComment.substring(0,14);
            else
                return CAjustComment;
    }

but i got this error, any one has an idea?
