property 'user.agent" was set to the unexpected value "unknown"

[james...@gmail.com]

Hi,

I just install GWT v1.3.3, and had a problem when running sample apps
in host mode. When the app is starting, an Internet Explorer popup
window appears with the following message

While attempting to load module "com.mycompany.MyApp", property
'user.agent" was set to the unexpected value "unknown". Allow values:
gecko, gecko1_8, ie6, opera, safari

I am running Windows 200 with IE 5.5, could this be the problem?
Suppose I can't update to IE 6 easily (company computer), is there
anything else I can modify to use Firefox as the browser being used in
host mode?

The dev shell has the following log:

[DEBUG] Rebinding com.google.gwt.user.client.impl.DOMImpl
[DEBUG] Checking rule <replace-with
class='com.google.gwt.user.client.impl.DOMImplMozilla'/>
[ERROR] Unable to get value of property 'user.agent'

The user agent is derived in the com/google/gwt/user/UserAgent.gwt.xml
file. You could try modifying that script and figuring out what is
going wrong. I'd take a look at the 'ua' var and see what your
browser is returning and why the logic isn't picking it up.

<property-provider name="user.agent">

var ua = navigator.userAgent.toLowerCase();
if (ua.indexOf("opera") != -1) {
return "opera";
}
else if (ua.indexOf("webkit") != -1) {
return "safari";
}
else if ((ua.indexOf("msie 6.0") != -1) ||
(ua.indexOf("msie 7.0") != -1)) {
return "ie6";
}
else if (ua.indexOf("gecko") != -1) {
var result = /rv:([0-9]+)\.([0-9]+)/.exec(ua);
if (result && result.length == 3) {
var version = (parseInt(result[1]) * 10) + parseInt(result[2]);
if (version >= 18)
return "gecko1_8";
}
return "gecko";
}
return "unknown";

</property-provider>

Err, now that i look at the script, it looks like your flavor of IE
isn't supported.

OK. Thanks! Is there a way to use Firefox as the browser in host mode?
I have difficulty to upgrade to IE 6 on my work computer.

As far as I know (which is quite far), that is non-trivial.

IE5.5 is flat out not supported by GWT.

bit of a pickle. Bring a linux boot CD? That doesn't sound like a
reasonable alternative, unfortunately.
