This works (using RC2); I cannot use an absolute path though (my
*.ui.xml and *.css files are in different packages). This works:
...
but neither of these do (both produce an "Unable to find resource" error):
...
...
The first one (src="/com/...") searches for
"com/myApp/moduleA/client/ui//com/myApp/core/client/resources/style.css"
(notice the double-slash); maybe a src="" starting with a slash could
be special-cased to be treated as an absolute path? (rather than
relative to the package containing the *.ui.xml file)
Would you like me to file an issue for this?

But then the @Shared CssResource's methods must only reference class
names, not constants, or you'll have a "The following obfuscated style
classes were missing from the source CSS file: [ERROR] red: Fix by
adding .red{}" error (my style.css contains a "@def red green;" and
the @Shared interface has a "String red()" method)
Thanks at lot anyway, I can now refactor my resources to have a
constants.css that can be referenced using src="" on in my
*.ui.xml files, and a @Shared CssResource with common CSS classes
(with the @Source referencing both common.css and constants.css to
import my @def's).
I'll get back to you if I ever have a problem in doing so ;-)

Re: [gwt-contrib] Reusing CssResource's @def (within e.g. UiBinder)
Just to be clear:
In the case at hand, where the shared CSS file has nothing in it but @def
values, there is nothing to be gained by an approach that is any more
complicated than:
.foo { color: yellow; }
But if you want to share actual class definitions, the @Shared mixin is the
way to go.

Re: [gwt-contrib] Reusing CssResource's @def (within e.g. UiBinder)
@bobv, please double check me here.
This will work, although I don't know if it will work in gwt/current or even
gwt/canary yet:
.foo { color: yellow; }
A ui:style element can have any number of css source files (space
separated). They'll be concatenated, and the body text appended to them. But
the ability for ui:style to have both a source css file and body text was a
fairly recent change. I doubt it's in gwt/current, and I'm not even sure
that it's in the long delayed gwt/canary.
@bobv, will anything pathological happen to the generated code if lots of
ui.xml files all do this? Remember that each ui.xml defines its own
ClientBundle.

[gwt-contrib] Reusing CssResource's @def (within e.g. UiBinder)
Hi all,
We're starting using UiBinder quite intensively and one thing we
haven't been able to do is to declare some constants in a CssResource
and reuse them in our ui.xml (I believe this is unrelated to UiBinder
actually, as I don't know how it could be made to work with plain old
CssResources only).
Our use case is I believe very common: declare constants for common
colors to be shared thoughout the app (namely some kind of orange and
grays for use with borders, fore color and back color). I suspect we
might have the need for font sizes too.
As a last resort, I tried the following (which forces me to have the
common CSS file in the same package as my ui.xml file):
@def yellow value('common.yellow');
.foo { color: yellow; }
but it fails with:
Scanning for additional dependencies: ...\gen\com\my\app\client
\Test_MyBinderImpl.java
Computing all possible rebind results for
'com.my.app.client.Test_MyBinderImpl_GenBundle'
Rebinding com.my.app.client.Test_MyBinderImpl_GenBundle
Invoking
Creating assignment for style()
Performing substitution in node color : .
;
[ERROR] Could not find no-arg method named yellow
in type com.my.app.client.Test_MyBinderImpl_GenCss_common
Is there a way to reuse @def-s in other CssResource-s? (in other
ClientBundle-s!) and which one?
