How to fight with a browser (Internet explorer) trivial problem?

Hi I'm facing a problem that I think it's quite trivial but I can't really understand it in the whole dimension:

Start point is a quite complex GWT project but I guess with a simpler will be the same, the project has 2 modules , the second inherits the first but again I doubt it could be important.

The resulting web app works great in chrome and safari but doesn't work in IE (both IE11 and Safari using the i.e. 10 or 9 engine as development option enables to) and doesn't work because can't identify the browser, indeed compiling in detailed mode and looking at JS inside IE I can see that the method

function computePropValue(propName) {
    var value_0 = providers[propName](), allowedValuesMap = values[propName];
    if (value_0 in allowedValuesMap) {
        return value_0;
    }
    var allowedValuesList = [];
    for (var k in allowedValuesMap) {
        allowedValuesList[allowedValuesMap[k]] = k;
    }
    if (propertyErrorFunc) {
        propertyErrorFunc(propName, allowedValuesList, value_0);
    }
    throw null;
}

throws null because while checking the browser $doc.documentMode is "undefined" and then it can't retrieve the correct nocache.js

my get.xml is something like

<entry-point ....

and my html starts as

<!doctype html>

<html>

<head>

Naturally I also tried to set user-agent to just safari and gecko and beside it works I have a warning that is telling me about the fact the browser isn't supposed to exist opening the page...

so:

1) why it can't find document mode? what I'm missing?

2) It's possible and how can I say that if the browser can't be identified must be used (without warnings!) a default permutation?

3) there's something I can do to better understand the behaviour?

Anyone?

IE11 uses the same permutation as Firefox, i.e. gecko1_8.Try with this user agent..I hope it solves your issue

Whats the user.agent of that IE 11 that does not work? ( http://whatsmyuseragent.com/ )

Already tried but no result...white page and JS errors, even in compatibility mode

Check your compilation-mappings.txt File Wether its generating js for "user.agent gecko1_8" or not...

Ok, I'm going to check, in the mean time I can say that forcing the user.agent to gecko make the webapp project work in safari emulating IE but no result in a real IE11, safari emulating IE works as:

Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Win64; x64; Trident/6.0)

This file is created by the xsiframe linkers family.

If you're not using 2.7 (where it's the default), you can (and should, unless you have a specific reason not to) activate it by adding <add-linker name="xsiframe"/> to your gwt.xml.

So, I have the agent for gecko for sure and i can see it but still that problem...debugging JS seems it accepts the user agent as IE but since can't find the version (that is unknown) all goes wrong

1) why it can't find document mode? what I'm missing?

No idea. Every IE 11 should have document.documentMode and GWT assumes that this is the case. Maybe your IE is somehow broken. You could try to use one of Microsofts free to use virtual machines to test against a fresh IE 11 installation. https://www.modern.ie

2) It's possible and how can I say that if the browser can't be identified must be used (without warnings!) a default permutation?

If you use GWT 2.7 you can do so using <set-property-fallback>.

3) there's something I can do to better understand the behaviour?

You need to figure out why document.documentMode does not exist in your IE 11.

Thanks Jens, I will try the point 2 suggestion but you must be wrong in other points since the problem is present in 3 different windows machines not related anyhow, in a virtual machine with a fresh IE 11 installation and happens also when I'm using IE emulation in Safari at any version...the problem must be in my GWT configuration..but I can't figure out where I have to search it.

I just noticed that in eclipse project properties I don't have any App Engine selected but all works...in other browser..any reason to select app engine? it's anyhow related to my IE problem?

You can not emulate IE in Safari / Chrome / Firefox because all these browsers only emulate the user agent value but do not emulate IE specific DOM properties like document.documentMode. So it is expected that GWT apps will fail if you use an IE user agent value with Safari / Chrome / Firefox since GWT now thinks it is an IE and tries to use documentMode to figure out which exact version of IE you are using.

You should only focus on real IE browsers.

&%$&** you right ! I wasted lot of time investigating in the wrong direction, the actual problem is

"Object doesn't support property or method 'addEventListener'" a totally different question!!

Ok, starting back now i'm facing the fact IE says "Invalid argument" on <!DOCTYPE HTML>

<!DOCTYPE HTML>

<html>

<head>

any guess?

after wasting a lot of time in the horrible java dev mode of IE i found was a set of cell height to 0%....in a wide application it's impossible to make guess using the basic support of IE...anyway...that's it..all right in the GWT project just IE don't like 0% as value....
