Rails Plugin for swfobject? - swf_fu

Hi all,

I''ve been using a plugin called swf_fu which seemed fairly easy to
implement for adding flash content to my rails app.  However, I''m
trying
to pass a variable to my flash through rails and have the flash content
pick it up.

The variable is already retrieved in an earlier call to the database so
I don''t believe it''s any type of authentication string issue.
Here''s
two examples:

<%=  swf_tag "victory.swf", :size => "250x75", :div_id
=> "flbars",
:flashvars => "victory_id=#{@virtuals_victory}", :parameters =>
{:wmode
=> ''transparent''} %>

OR

<%=  swf_tag "victory.swf", :size => "250x75", :div_id
=> "flbars",
:flashvars => {:victory_id => @virtuals_victory}, :parameters =>
{:wmode
=> ''transparent''} %>

As a generic test, I''m passing the following value with
@virtuals_victory by doing @virtuals_victory = 76.

In my flash I''m doing:

onSelfEvent (load) {
    victoryID = this.loaderInfo.parameters.victory_id;
}

.. which is going to pull the victory_id value sent to it through
swfobject''s flashvars.

When I pull it up, it doesn''t show the value and the source shows the
following:

swfobject.embedSWF("/swfs/victory.swf?1248962132","flbars","250","75","7","/swfs/expressInstall.swf?1248568039",{"victory_id":"76","id":"victory"},{"wmode":"transparent"},{"id":"victory"})

As you can see, right after the expressInstall, the flashvars hash is
showing "victory_id":"76" in the first case and in the
second case it
shows "victory_id":76.

Does anyone have an idea of why flash isn''t retrieving the flashvars
with swfobject?  I''ve checked the readme of the plugin and it says:

=== Options

* :id - the DOM +id+ of the flash +object+ element that is
used
to contain the Flash object; defaults to the name of the swf in +source+
* :width, :height - the width & height of the Flash
object.
Defaults to "100%". These could also specified using :size
* :size - the size of the Flash object, in the form
"400x300".
* :mode - Either :dynamic (default) or :static. Refer to
SWFObject''s
doc[http://code.google.com/p/swfobject/wiki/documentation#Should_I_use_the_static_or_dynamic_publishing_method?]
* :flashvars - a Hash of variables that are passed to the
swf.
Can also be a string like
"foo=bar&hello=world" . Defaults to
{:id => the DOM id}
* :parameters - a Hash of configuration parameters for the
swf.
See Adobe''s
doc[http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_12701#optional]
* :alt - HTML text that is displayed when the Flash player
is
not available. Defaults to a "Get Flash" image pointing to Adobe
Flash''s
installation page. This can also be specified as a block (see embedding
section)
* :flash_version - the version of the Flash player that is
required (e.g. "7" (default) or "8.1.0")
* :auto_install - a swf file that will upgrade flash player
if
needed (defaults to "expressInstall" which was installed by swf_fu)
* :javascript_class - specify a javascript class (e.g.
"MyFlash") for your flash object. If it exists, the initialize method
will be called.
* :initialize - arguments to pass to the initialization
method
of your javascript class.
* :div_id - the DOM +id+ of the containing div itself.
Defaults
to "#{option[:id]}"_div
* :switch_off_auto_hide_show - switch off
SWFObject''s default
hide/show behavior. SWFObject temporarily hides your SWF or alternative
content until the library has decided which content to display. Defaults
to nil.


So, at this point I''m not understanding why I can''t get this
to work.
I''ve also tried doing:

skip_before_filter :verify_authenticity_token

.. on the controller processing the variable ..

Any advice on this issue?
