AjaxControlToolkit错误：tsm combinedscripts = true

Question

我一直在收到有关toolscriptmanager的应用程序的错误。请参阅以下例外情况：

Error Message: Exception of type 'System.Web.HttpUnhandledException' was thrown.

Inner Exception: 

System.ArgumentNullException: Value cannot be null.
Parameter name: value
   at System.Boolean.Parse(String value)
   at AjaxControlToolkit.ToolkitScriptManagerCombiner.OutputCombinedScriptFile(HttpContextBase context)
   at AjaxControlToolkit.ToolkitScriptManager.OnInit(EventArgs e)
   at System.Web.UI.Control.InitRecursive(Control namingContainer)
   at System.Web.UI.Control.InitRecursive(Control namingContainer)
   at System.Web.UI.Control.InitRecursive(Control namingContainer)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

有没有人知道这可能是什么？我一直在引用this票证，但似乎无法复制错误。
