Rhodes-Problem in executing methods from the native extension.

Hi,

I created new rhodes application in rhostudio and added a native extension by executing the command "rhogen extension ext"

Then I got two folders created inside my project.

ExTest\app\ExtTest

ExTest\extensions\ex

in the index.erb inside the app folder I added a link to the ExtTest like this.

<div data-role="content">

    <ul data-role="listview">

      <li><a href="ExtTest">ExtTest</a></li>

    </ul>

  </div>

When I run the app and click this link index.erb inside the ExtTest folder is loaded.
This is the code of that file.

<div data-role="page">0

  <div data-role="header" data-position="inline">

    <h1>Ext Extension Test</h1>

    <a href="<%= Rho::RhoConfig.start_path %>" class="ui-btn-left" data-icon="home" data-direction="reverse"

  </div>

  <div data-role="content">

    <ul data-role="listview">

        <%= link_to 'Run Ext test', { :action => :run_test }%>

    </ul>

  </div>

</div>

run_test is a method in exttest_controller.rb inside the ExtTest folder.

require 'rho/rhocontroller'

require 'helpers/application_helper'

require 'helpers/browser_helper'

require 'ext'

class ExtTestController < Rho::RhoController

  include BrowserHelper

  include ApplicationHelper

  def index

    render :back => '/app'

  end

  def run_test

    sum = Ext.calc_summ(3,7)

    Alert.show_popup Ext::ExtStringHelper::process_string('test')+sum.to_s

    render :action => :index, :back => '/app'

  end

end

When I click the link "Run Ext test" the method run_test is not invoked.

http://127.0.0.1:49975/app/ExtTest/run_test

This URL seems to be broken.

And I can't find out a reason for this error. Can anybody help me on this issue?
