Apache – Papervision Glitches

I found a way around this on my Flex on Rails application. I was seeing the same problem in IE - my development.log in Rails gave a 201 message, but this caused a fault coming back to Flex. I found a reference in a new book called Flex On Rails by Tony Hillerson and Daniel Wanja, on p. 31. It involves catching the 201 error and changing the header. Here's my ApplicationController file:

 class ApplicationController < ActionController::Base
  helper :all # include all helpers, all the time
  include AuthenticatedSystem
  before_filter :login_required


  after_filter :flex_error_handling
  def flex_error_handling
    response.headers['Status'] = interpret_status(200) if response.headers['Status'] == interpret_status(422)
    response.headers['Status'] = interpret_status(200) if response.headers['Status'] == interpret_status(201)
  end
  def rescue_action_in_public(exception)
    render_exception(exception)


  end
  def rescue_action_locally(exception)
    render_exception(exception)
  end
    rescue_from ActiveRecord::RecordNotFound, :with => :render_exception
  def render_exception(exception)
    render :text => "<errors><error>#{exception}</error></errors>", :status => 200
  end
end

The action of changing the 422 status message to 200 was part of Hillerman/Wanja's original suggestions to change the 2032 Stream Error into something more friendly, so that invalid record errors are sent back to the Flex UI.

If you're using 3dsMax you'll need to get a plugin to export the collada file. The default export doesn't work properly. If you're using 3dsMax 2009, you'll need a special version of the plugin.

I believe that this is it: http://www.flashbookmarks.com/pv3dchat/ColladaMax2009.zip

Once you know that your dae file is correct, you'll need to build a MaterialsList object with each of the materials that your 3D file will use. It's a bit of work but after you've done that everything should be good. Make sure the name of your materials in the MateriasList are the same as they are in your 3d program. They'll be mapped to the 3d object by their name.
