I download beta10 and create a default project in eclipse. I got a error on "VAADIN/vaadinBootstrap.js" when I use IE8.
It's seem IE8 not support XMLHttpRequest object.
I had try to modify vaadinBootstrap.js to add ActiveXObject, then the simple UI can be successful load in IE8.
[i]
if ( window.XMLHttpRequest )
{
r = new XMLHttpRequest();
} else
{
r = new ActiveXObject(“MSXML2.XMLHTTP.3.0”);
}
[/i]
Vaadin 7 supports IE8 and we run all our tests in IE8 and IE9 and have never seen such an error. However after surfing the web for a while it turns out you can disable “Native XMLHttpRequest” in IE8 settings and this will cause the “Object Expected” message. I have no clue why you would ever want to disable this but I created
http://dev.vaadin.com/ticket/10423 for this.
Very thanks your response, I check my IE setting, just as you said, ‘Native XMLHttpRequest’ option was disabled.
I didn’t remeber any issue to do that, and I learned one very useful KB.
