[Wicket-user] How to escape string? wicket.util.string.Strings.escapeMarkup

[叶卫国]

 it seems that wicket.util.string.Strings.escapeMarkup method does not escape " 
 and ', so when i input a " or ', the display is error.
 who can fix it? thanks.

  public static String escapeMarkup(final String s, final boolean escapeSpaces)
        {
                if (s == null)
                {
                        return null;
                }
                else
                {
                        final StringBuffer buffer = new StringBuffer();

                        for (int i = 0; i < s.length(); i++)
                        {
                                final char c = s.charAt(i);

                                switch (c)
                                {
                                        case '\t' :
                                                if (escapeSpaces)
                                                {
                                                        // Assumption is four 
space tabs (sorry, but that's
                                                        // just
                                                        // how it is!)
