  Try to add a FieldValueExtractor to a DataSourceField, that basicaly does
nothing:

field.setFieldValueExtractor(new FieldValueExtractor() {

            public Object execute(Object record, Object value,
                return null;
            }

        });

and by starting the application, you will get the following exception;

com.google.gwt.dev.shell.ie.IDispatchImpl$HResultException:
java.lang.IllegalArgumentException: object is not an instance of declaring

yeah, that api has not yet been implemented.

Fixed in SVN.

Sample usage :

DataSourceTextField customField = new DataSourceTextField("countryCode", "Code 
/ Continent");
customField.setFieldValueExtractor(new FieldValueExtractor() {
    public Object execute(Object record, Object value, DataSourceField field, String fieldName) {
        String countryCode = XMLTools.selectString(record, "countryCode");
        String continent = XMLTools.selectString(record, "continent");
        return countryCode + "/" + continent;
    }
});

I am having exactly the same problem here. Updated to GWT 1.1 already, but 
nothing
changed at all. There is also no note about FieldValueExtractor interface in the
release notes.

Please post a standalone test case. The code snippet I posted works fine when 
used with the Showcase samples 
Country Datasource.

Unfortunately I can not post a standalone test case, because my company policy 
does
not allow posting any of their code. But I can assure you, that my code looks 
very
similar to your example.

The only distinction is, that I am using a server response in XML format rather 
than
parsing a static XML-File.

My stacktrace looks exactly the same.

I am just wondering, because the API change history does not say anything about 
the
FindValueExtractor either.

The standalone test case doesn't have to be your company code. Just create a 
new simplified sample, or 
modify a showcase sample so that the error is reproduced.

Also make sure your xml response has the correct content-type header.

The API hasn't changed. Previously the implementation didn't quite exist (as 
noted in by the reporter of this 
issue) but it now does. 

Again, I have tested that it works using this API with the Country XML 
DataSource. Unless you create a sample 
that reproduces the issue, we cannot tell whats going on.
