Hi everyone, I am using an AjaxFormLoop in a page. However, after I load the page with the AjaxFormLoop and a few minutes have passed, when I click the "Add row" link I get the following exception and a new row is not added. However, if I click it again, then no exception is shown and a new row is added. Does anyone know what can be causing it? I am using Tapestry 5.1.0.8
