    TokenNotUniqueException: Token is not unique

    Hi,

    with new version of ext.net (Ext.NET.WebForms.Pro.2.1.1) when i add a module to desktop at runtime i've this error:

    [TokenNotUniqueException: Token is not unique
-------------------
ID = ctl26_ClientInit
TagName = anchor
Match = <#:anchor id="ctl26_ClientInit" />
]
   Transformer.NET.Token.ParseAnchors() +532
   Transformer.NET.TextTransformer.Parse(List`1 tokensType, Dictionary`2 variables) +1088
   Transformer.NET.TextTransformer.Transform(List`1 tokensType, Dictionary`2 variables) +42
   Transformer.NET.TextTransformer.Transform(List`1 tokensType) +40
   Transformer.NET.TextTransformer.Transform() +56
   Ext.Net.ExtNetTransformer.Transform(String text) +213
   Ext.Net.InitScriptFilter.Transform() +52
   Ext.Net.InitScriptFilter.Flush() +79
   System.Web.HttpWriter.Filter(Boolean finalFiltering) +8797420

   System.Web.CallFilterExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +52
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

    the web.config is configured with clientIDMode="AutoID", Target Framework = 4.0

    Note: with the previous version works fine (Ext.net v 2.0.0)

    Thanks,
    Valeriano

    It means that control with ID=ctl26 is added several times, like
    Button b = new Button();
Panel1.Buttons.Add(b);
Panel2.Buttons.Add(b);

    In any case, it would be best if you can provide simple test case

    At this moment, I can suggest to remove
    desktop.Modules.Add(desktop_module.Module)
    It should work for initial page load request

    Another option, add for PreventAdding=true DesktopModuleProxy
    In this case, the module will not be registered automatically and you need to add it to desktop modules manually

    both solutions work fine.
