Rails spinoffs - Apr 2008 - Ajax.inPlaceEditor is not updating when it's a textarea and there is a newline character

Did anybody experience this problem?

In Firefox using Ajax.inPlaceEditor, after saving, the innerHTML of
the target div is not updating when you have multiple lines of input
(rows >= 2) and there is a newline character in the text content.  It
works fine if you don''t have a "\n" in the text content.  It
just says
"Saving . . . . " and doesn''t update.

I''m passing { rows: 2 } in as an option to Ajax.inPlaceEditor, and
updating my div with $(''box_text'').update(''here is
some text'');

Is there a more robust way to update the value in the <div>
innerHTML ?  Thank you!

The relevant code is pasted below:

# XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

The column is a text data type in the database.  (the column also
happens to be called "text")
I wrote a helper method called "ipe" to make these DRYer:

    <div class="text" id="text_<%= @box.id
%>"><%= ipe @box, :text,
{:rows => 3} %></div>

This is my helper method generating the call:

  def ipe instance, property, options={}
    class_name = instance.class.to_s.downcase # in lower case
    path = instance.class.to_s.pluralize.downcase
    dom_id = "#{class_name}_#{property}"
    value = instance.send(property)
    option_text = ""
    option_text << "rows: #{options[:rows]}," if options[:rows]
    return %(
<div id=''#{dom_id}''>#{value}</div>
    <script type=\"text/javascript\">
      new Ajax.InPlaceEditor($(''#{dom_id}''),
''/#{path}/'' +
#{instance.id}, {
          #{option_text}
          htmlResponse: false,
					ajaxOptions: {method: ''put''},
			    callback: function(form, value) {
					return ''authenticity_token='' +
''#{form_authenticity_token}'' +
''&#{class_name}[#{property}]='' + escape(value) }
		   	  });
    </script>
    ) # return

  end # ipe

Here is my rjs file:

Box.content_columns.each do |c|
  property = c.name
  page <<
"$(''box_#{property}'').update(''#{@box.send(property)}'');"
if
params[:box][property.to_sym]
end

In case anybody wants to know, I encoded \n to <br> in the database,
then when I send it back to the browser from the server, there are no
\n characters.  Then upon displaying it in the textarea, I convert all
the <br> to \n.  It seems to work well doing it like this.
