[Xsltforms-support] Problem with upload in IE8 without Java installed (it is not clear to user that Java is needed)

[Javier D. <jd...@tc...>]

Hello,

In order to test my web with IE, I installed a virtual machine to test it.

When testing upload control, it didn't work, it didn't load the applet,
but no error message appeared.

Another person tested it and I realized I hadn't java installed in my
virtual machine.

The only problem with IE8 and Java is that it doesn't appear a clear
error that says to you that you need Java to use the web. Instead, it
appear a javascript error in IE that people don't pay attention to it.

I have done this change in my xsltforms version in order to make clear
that Java is not installed:


        if (document.applets.xsltforms) {
                return document.applets.xsltforms.readFile(fname,
encoding, xsdtype, title) || "";
        } else {
-               if( document.getElementById("xsltforms_applet") ) {
+               if( document.getElementById("xsltforms_applet") &&
(typeof document.getElementById("xsltforms_applet").readFile !=
'undefined')) {
                        return
document.getElementById("xsltforms_applet").readFile(fname, encoding,
xsdtype, title) || "";
                } else {
                        XsltForms_browser.loadapplet();
                        if (document.applets.xsltforms) {
                                return
document.applets.xsltforms.readFile(fname, encoding, xsdtype, title) || "";
                        } else {
-                               if(
document.getElementById("xsltforms_applet") ) {
+                               if(
document.getElementById("xsltforms_applet") && (typeof
document.getElementById("xsltforms_applet").readFile != 'undefined')) {
                                        return
document.getElementById("xsltforms_applet").readFile(fname, encoding,
xsdtype, title) || "";
+                               } else {
+                                   alert("Error: Java no está
habilitado. Es necesario Java para subir ficheros en Internet Explorer");
                                }
                        }
                }

(Alert message is intentionally in Spanish, because is an internal web)

I hope it is useful to anybody.

Best Regards,
Javier
