Hi i have attached a project where the error happens in WebForm1.aspx when you move from testTextBox to TextBox1, you might have to change the value of testTextBox before moving.
The validator doesn't trigger and the error "Out of stack space" gets written to IE Console.
I think "Sys.Extended.UI.TextBoxWrapper.validatorGetValue" is calling its self there by creating a loop that never exits..
Comments: I've updated source code to avoid script duplication in this situation. You can download the latest [source code](https://ajaxcontroltoolkit.codeplex.com/SourceControl/latest) of the AJAX Control Toolkit and include your sample project into solution. Please let me know if this change helped you
