      There is not workaround unless disabling filter in RichFaces configuration.

      A value input into an inputTextarea of JSF tag is trimmed white-space characters automatically when data gets rendered in page.

      Trim handling for the inputTextarea is the following (org.ajax4jsf.org.w3c.tidy.ParserImpl.java)
      3115#    /**
3116#     * Parser for text nodes.
3117#     */
3118#    public static class ParseText implements Parser
3119#    {
3120#
3121#        /**
3122#         * @see org.ajax4jsf.org.w3c.tidy.Parser#parse(org.ajax4jsf.org.w3c.tidy.Lexer, org.ajax4jsf.org.w3c.tidy.Node, short)
3123#         */
3124#        public void parse(Lexer lexer, Node field, short mode)
--- snip ---
3240#            while ((node = lexer.getToken(mode)) != null)
3241#            {
3242#                if (node.tag == field.tag && node.type == Node.END_TAG)
3243#                {
3244#                    field.closed = true;
=> 3245#                    Node.trimSpaces(lexer, field);
3246#                    return;
3247#                }
3248#
3249#                // deal with comments etc.
3250#                if (Node.insertMisc(field, node))
3251#                {
3252#                    continue;
3253#                }
