I'm trying to build a GUI Extension to 2011. One of my requirements is that there be a 'settings' page for this extension that a Tridion user can access from the Ribbon. 

When Tridion loads, the GUI does not complete loading, and the console shows this error message:

> 
> Unable to get unique id for element. Dashboard\_v6.1.0.55920.8\_.aspx:22
> 
> 
> 

Below is a snippet from my configuration file. I'm trying to understand what the issue is and where it originates. Is it my configuration, my JavaScript, or both?

```
<ext:deckpages>
       <ext:add>
         <ext:extension pageid="ToolsPage" name="CrocodocSettingsPage" assignid="CrocodocSettingsPage">
           <ext:control>~/Controls/CrocodocSettings.ascx</ext:control>
           <ext:pagetype>crocodoc.SettingsPage</ext:pagetype>
           <ext:dependencies>
             <cfg:dependency>crocodoc.Resources.Settings</cfg:dependency>
           </ext:dependencies>
         <ext:apply>
           <ext:view name="DashboardView">
             <ext:control id="DashboardToolbar" />
           </ext:view>
         </ext:apply>
         </ext:extension>
       </ext:add>
     </ext:deckpages>
     <ext:tabpages />
     <ext:toolbars />
     <ext:ribbontoolbars>
       <ext:add>
         <ext:extension pageid="ToolsPage" groupid="MaintenanceGroup" name="croc" assignid="croc">
           <ext:command>crocodoc</ext:command>
           <ext:title>Crocodoc Configuration</ext:title>
           <ext:dependencies>
             <cfg:dependency>crocodoc.Resources.Settings</cfg:dependency>
           </ext:dependencies>
         <ext:apply>
           <ext:view name="DashboardView">
             <ext:control id="DashboardToolbar" />
           </ext:view>
         </ext:apply>
         </ext:extension>
       </ext:add>
     </ext:ribbontoolbars>
   </ext:editorextension>
 </ext:editorextensions>
    <ext:dataextenders/>
</extensions>

```

 crocodoc.Resources.Base

Update
======

I've updated the configuration, But I'm still having the same error. It's on line 22. The Console shows me these full details of the object:
