title: Magento - Can't Save Role Resource for Custom Module
body: <p>I’ve created a custom module and my config.xml is as follows… </p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
    &lt;config&gt;
     &lt;admin&gt;
      &lt;routers&gt;
          &lt;blacklist&gt;
              &lt;use&gt;admin&lt;/use&gt;
              &lt;args&gt;
                  &lt;module&gt;Leon_Blacklist&lt;/module&gt;
                  &lt;frontName&gt;blacklist&lt;/frontName&gt;
              &lt;/args&gt;
          &lt;/blacklist&gt;
      &lt;/routers&gt;
  &lt;/admin&gt;
  &lt;adminhtml&gt;
      &lt;menu&gt;
          &lt;blacklist translate="title" module="blacklist"&gt;
              &lt;title&gt;Blacklist&lt;/title&gt;
              &lt;sort_order&gt;71&lt;/sort_order&gt;               
              &lt;children&gt;
                  &lt;items translate="title" module="blacklist"&gt;
                      &lt;title&gt;Manage Items&lt;/title&gt;
                      &lt;sort_order&gt;0&lt;/sort_order&gt;
                      &lt;action&gt;blacklist/adminhtml_blacklist&lt;/action&gt;
                  &lt;/items&gt;
              &lt;/children&gt;
          &lt;/blacklist&gt;
      &lt;/menu&gt;
      &lt;acl&gt;
          &lt;resources&gt;
              &lt;all&gt;
                  &lt;title&gt;Allow Everything&lt;/title&gt;
              &lt;/all&gt;
              &lt;admin&gt;
                  &lt;children&gt;
                      &lt;Leon_Blacklist translate="title" module="blacklist"&gt;
                          &lt;title&gt;Blacklist Module&lt;/title&gt;
                          &lt;sort_order&gt;10&lt;/sort_order&gt;
  
                          &lt;children&gt;
                              &lt;items translate="title" module="blacklist"&gt;
                                  &lt;title&gt;Manage Items&lt;/title&gt;
                              &lt;/items&gt;                        
                          &lt;/children&gt;
                      &lt;/Leon_Blacklist&gt;
                  &lt;/children&gt;
              &lt;/admin&gt;
          &lt;/resources&gt;
      &lt;/acl&gt;
      &lt;layout&gt;
          &lt;updates&gt;
              &lt;blacklist&gt;
                  &lt;file&gt;blacklist.xml&lt;/file&gt;
              &lt;/blacklist&gt;
          &lt;/updates&gt;
      &lt;/layout&gt;
  &lt;/adminhtml&gt;

  <p>The module works as expected if an admin account is logged in. I can see the module in the admin panel and in the Role Resource Tab (System->Permissions->Roles), but when I tried to check the module and save the user role, it will say that it has been saved. But when I rechecked the user role, it is still unchecked.</p>
  
  <p>And when I tried to login using the account with the said user role, the custom module is hidden. What seems to be the problem? Any kind of help is much appreciated..</p>
  
  <p>Thanks. </p>
