Body
Are <code>Predicate</code>s and <code>Function</code>s supported in GWT 2.4.0 and Guava GWT 10.0.1? Both interfaces are marked as <code>@GwtCompatible</code>. When running the project in debug hosted mode, I receive run-time validation errors at the uses of <code>Predicate</code>: <blockquote> [ERROR] [MyProject] - Line XXY: The import javax.annotation.Nullable cannot be resolved [ERROR] [MyProject] - Line YYY: Nullable cannot be resolved to a type </blockquote> From other StackOverflow posts, I believe these errors should not require including JSR 305 in the path as of Guava version 09 (including JSR 305 in the path didn't fix the problem, anyway). I also appear to receive a couple interface mismatch errors: <blockquote> [ERROR] [MyProject] - Line XXX: The type new Function(){} must implement the inherited abstract method Function.apply(Object) [ERROR] [MyProject] - Line YYY: The method apply(MyType) of type new Function(){} must override or implement a supertype method </blockquote> , and similar errors at uses of <code>Predicate</code>, which I submitted as a bug: <a href="http://code.google.com/p/guava-libraries/issues/detail?id=765" rel="noreferrer">http://code.google.com/p/guava-libraries/issues/detail?id=765</a> Any ideas as to what might be wrong with my setup? My Project.gwt.xml file contains the following lines: <pre><code><inherits name="com.google.common.collect.Collect" /> <inherits name="com.google.common.base.Base" /> </code></pre> My java file includes the following imports: <pre><code>import com.google.common.base.Function; import com.google.common.base.Predicate; </code></pre> I am using Eclipse 3.7.1 and JavaSE-1.6

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
