OK, found the cause of the problem. I had an HTML inserted in a div which has a form that the user has to fill. The error appeared on clicking on the submit button.
I short, the html of the form is something like this: <form id="adq_formulario" method="post" name="fadquisicion"> <table border="0" cellpadding="5" width="467" > <tr> <td colspan="2" class="titform"> <h2>Formulario para solicitud de material nuevo para adquisición</h2> </td> </tr> <tr> <td colspan="2" class="texto"> Los campos con <span class="obligatorio">(*)</span> son obligatorios </td> </tr> <tr> <td class="titulo" id="td_adq_titulo">Titulo del material: <span class="obligatorio">(*)</span></td> <td> <INPUT id="adq_titulo" type="text" value="{TITULO}" name="titulo" size="40" maxsize="200"> </td> </tr> <tr> <td class="titulo" id="td_adq_autor">Autor o autores del material: <span class="obligatorio">(*)</span> </td> <td> <INPUT id="adq_autor" type="text" value="{AUTOR}" name="autor" size="40" maxsize="200"> </td> </tr> </table> </form> Solution: eliminate the <form> tags. After that, it started working. This is not the first time this happens to me. Why's prototype so unhappy with form tags?
