Not sure if this is the place to add this but just wanted to pass on my
finding related to IE10 browser support.
I ran into an issue with GWT cellTables and cellTrees using IE 10. When
hovering over a row we used hovering styling for that row which worked
fine.
However, if we stayed hovering over the row and the cellTree refreshed the
hovering styling would disappear.
This was due to events like load and mouseover not firing for the cell
widgets as it does with other browsers and lesser IE versions. I followed
through the GWT code and found that since GWT cannot resolve the ie10
user.agent so the user.agent for ie6 is used.
I have verified this at many points in the code, but if you set a break
point on line 36 in com.google.gwt.dom.client.DOMImplIE6 you will see first
that this class is called and that *isIE6Detected *is set to true;
*static* *boolean* isIE6() {
*if* (!*isIE6Detected*) {
*isIE6* = *isIE6Impl*();
*isIE6Detected* = *true*; !-- Line 36
}
*return* *isIE6*;
}
I was thinking about the following two options, but am going to run them by
more experienced members of our team.
*Option #1*
Since we are performing an upgrade to 2.5.1 now we could modify these 3
files to include an IE10 user agent and set it to fall back to IE8 as is
IE9 currently in UserAgent.gwt.xml. They appear to be simple changes.
com.google.gwt.useragent.UserAgent.gwt.xml
com.google.gwt.useragent.rebind.UserAgentPropertyGenerator.java
com.google.gwt.user.DOM.gwt.xml
*Option #2 *(Admitted hack)
Since IE6 is no longer supported and IE10 is resolving to the IE6 user
agent then this added to our Common.gwt.xml solves the problem and can be
removed when a gwt support user agent IE10.
replace-with class=com.google.gwt.dom.client.impl.DOMImplIE9
when-type-is class=com.google.gwt.dom.client.impl.DOMImpl/
when-property-is name=user.agent value=ie6/
/replace-with

In most cases that is true, but CssResource is an interesting exception.
The fallback rules work by looking to see if there is no implementation for
a particular value, and if not, looking to see if there *is* an
implementation for some other value. In the case of ClientBundle and
CssResource, they are generated at compile time - when you refer to @if
user.agent ie9, that will be compiled *only* into the ie9 build, and not
into any ie10 build, which will only contain non-qualified code or
statements that actually evaluate to true for ie10.
But yes, otherwise it should behave as you've described.

It does but out of curiosity, if I add IE10 permutation/browser detection
to UserAgent.gwt.xml to which value should I set the property-fallback? I
mean is property fallback-recursive (I would assume it is) so setting it to
IE9 should work? In case IE9 rule isn't specified it will recursively
fallback to IE8 (and generate a compiler warning) right?

When you add support for IE10??
AFAIK, IE10 works OK with the ie9 permutation.
Vaadin has started working on bringing MSPointerEvents to support
touch-enabled (and touch-only) devices.
