Hi,

Before explain my problem, I have to say that my GWT version is 2.2.0
and the error only has place when I use Internet Explorer (in this
case IE 8).

I have a little GWT project which contains a button that throws the
next method:

       private void expotarExpediente(VistaExpediente vista) {
               final String templateURL = GWT.getHostPageBaseURL() + "exportar?id="
                               + vista.getId();
               Window.open(
                               templateURL,
                               "Resultado de expotar el expediente: "
                                               + vista.getNumeroExpediente(), "");
       }

This method creates a template URL to call to a classic HTTPServlet
("exportar") which generates a Zip File to download by users.
The sentence  Window.open(...) open a window in the browser that
allows download the file.

This works correctly in all browsers except Internet Explorer.
The thrown exception is the next:

The thrown exception is the next

I can´t find any decent solution searching by google. I would like if
someone has had this problem before and if he or she could overcome
it.

Thanks and excusme for my poor English.
