HtmlInputSpinner freaks out with formatted numbers
--------------------------------------------------

                 Key: RF-4450
                 URL: https://jira.jboss.org/jira/browse/RF-4450
             Project: RichFaces
          Issue Type: Feature Request
    Affects Versions: 3.2.2
         Environment: All
            Reporter: Richard Kennard
            Priority: Minor


HtmlInputSpinner completely loses the plot if it has a Converter attached that formats the number.

For example, a Converter that formats the number from 1234 to $1,234.00 or 1234%. As soon as you click a spinner button, the value jumps to, say, 9E+2 or something, which I assume is a result of failure to parse the number. I appreciate that because the 'spinning' is client-side and JavaScript based it does not have access to the Converter to help it parse the number.

However, it would be great to have some level of support such as:

BEST: support formatted numbers directly (eg. HtmlInputSpinner.setNumberPattern)
STILL GOOD: strip non-numeric characters when parsing the number (eg. $ and % and ,)
OKAY: grab the original value server-side, pre-going through the Converter, and use that to drive the spinner's JavaScript (being wary, of course, if the user edits the value manually by typing in the text box)
