It should be registered via or entry in your .gwt.xml ?
I include a background image in a css file through a @sprite annotation and
do get a warning (see subject and below) that it should be included in the
gwt.xml gwt file.
How should this be done? The documentation still describes it like I use it
below that results in a warning.
Details:
Css file:
@sprite .Bla {
gwt-sprite: "quickCheck";
}
And in the ClienBundle class it's included as:
@Source("quickCheck.jpg")
ImageResource quickCheck();
And get the following console warning:
As a result changes in that resource will not be reflected in per-file
recompiles. It should be registered via or entry in
your .gwt.xml. In a future version of GWT, we will remove this fallback and
your application will stop compiling

Re: [ERROR] Only either css files or gss files are supported on one interface
Thanks for the explanation @Jens. I think I understand why the extension is important. So we can't let go if that requirement. But let's go back to the original error (subject of the topic). If I understand you correctly, I could be able to mix css and gss files by using the correct extension. In case it concerns a css file, the gss mechanism will sue the css2gss converter to create the gss file before passing it to to the closure compiler. But that is what I am doing, so why isn't that allowed? - Ed -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Small update here: I was able to get my test to break again even after
using the #accept() idea, by using a Map property in the bean, and
iterating over its entry set. So my conclusion here: using autobeans on the
server side without external synchronization and careful coding is
dangerous.
I've now worked around this issue by copying the contents of the bean into
a separate class that implements the bean interface as well. In my case I
do not need the ability to modify the contents, so I didn't bother working
out how I'd get my copy serialized into JSON again.

Re: [ERROR] Only either css files or gss files are supported on one interface
What you are asking for is simply not possible in a reliable way under the
requirement that old css syntax needs to be converted to gss syntax to
avoid producing compile errors when activating GSS for a project.
When I give you (which is hopefully similar to your use case):
@Source({ app-constants.gss, library-constants.css, library-mywidget.css,
app-mywidget.gss })
Then what should GWT do to produce valid GSS code that can be handed over
to closure stylesheets?
- The ordering of files is important as later files can override CSS rules
in previous files (e.g. library-mywidget could produce a red widget by
default and app-mywidget overrides it to a blue gradient)
- Any css file might be compatible with GSS as-is but maybe it is not. If
you can not use the file extension to decide it you need to try parsing a
css file using a GSS parser. If it fails it is incompatible and would need
to be converted using the css2gss in-memory converter.
- app-mywidget.gss might reuse constants provided by library-constants.css
as well use constants from app-constants.gss.
So what would you do now?
1.) You can not try parsing each file one-by-one to figure out if it is GSS
compatible because each file might use constants provided by other files.
If the parser does not see the constant definition it would fail even
though the file might be GSS compatible. The parser needs complete
knowledge.
2.) Because of the previous you need to merge all files before parsing so
you have all information available. Parsing the merged data might work if
the css files are GSS compatible in which case you would hand over the
merge result to closure stylesheet to parse it again and produce the final
css output. However if the merged data fails to parse then you know that
some files are incompatible but not wich ones. So you don't know if its
because of a GSS syntax error in one of the gss files (in which case you
would fail the compile) or if its because one of the css files contain
legacy syntax that needs to be converted using the in-memory converter.
To figure that out you would need to assume that css files are
incompatible, merge just the css files (because of 1. and because the
converter does not want gss input)), run them through the css2gss converter
and finally merge the conversion result with the remaining gss files.
However when doing so you might have changed the ordering of css rules that
needs to be avoided as it changes rendering behavior.
So the only way to make it fool proof for GWT is to assume that *.css files
must always be converted and that *.gss files can be used as-is and that
you can never mix them for a given CssResource. And that is exactly what
GWT does.
So in your case you need to provide gss and css files for your widgets. You
can generate the gss files from the css files by using the css2gss tool
provided in gwt-user.jar. GWT itself does the same for its widgets.

Provide implementations for List/Set/Map proxy properties
I have server-side bean:
public class Author {
public Map getAttributes() { /* ... */ }
public void setAttributes(Map attributes) { /* ... */ }
}
and its RF proxy type:
@ProxyFor(value=Author.class, locator=AuthorLocator.class)
public interface AuthorProxy extends EntityProxy {
Map getAttributes();
void setAttributes(Map attributes);
}
Is there a way to provide custom instances of Map that will
be used when constructing proxy autobean?
According to docs, it seems that AutoBeanFactory.Category may provide
implementation for additional methods in proxy interface that could do
converting to/from MyMapClass but I wonder if it is possible to construct
proper instances imediatelly upon autobean deserialization? I'm aware that
it will still require casting return values to my class, but that is
acceptable compromise).

Re: [ERROR] Only either css files or gss files are supported on one interface
Thanks @Jens, I understand what you mean. However, I still not see a could reason to force the gss file extension. I think we can assume that the developer knows what he is doing and it's his responsibility to feed the gss engine with the correct files, giving him the freedom to use any extension he wants. I understand that it's a nice separation, and it's how other css generation tools work. But Gwt is a bit different and does more then just css generation, so in this case it has some blocking disadvantages. Advantages of allowing the css extension: shared code use, merging to gss step by step. Let me explain it through my use case: I have a gwt code base that exists of many widget having their own resource bundle and css files (empty mostly, following to the adapter pattern). New projects want to use css3 features, as such need the gss mechanism. However, these shared resource bundles can't be changed, as it results in breaking other projects using them. Neither do I want to change them as mostly they concern empty css files that aren't gss dependent, which they would look like it if they have the gss extension. To solve this I see 2 options: duplicating the shared css files and giving them the gss extension -> a lot of work, messy maintainable code. Patching the gwt gss engine to allow for css files with the css extension. I think I go for the last option as it seems an easy one looking at the gss code. I would suggest to allow for the css extension. Optional with a console warning that can be suppressed (like done in other parts of the gwt code). I understand that the css files might contain some gwt syntax like @def that might result in unwanted results when processed by gss. But isn't that the same as letting Spring eat some hibernate syntax that it understands and results in strange outcome It's the responsibility of the developer to overcome that So give him that freedom What do you think? Just my 50 cents. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
