    <p>What im trying to do is to create map, where key will be class which extends my abstract class</p> <pre><code>GinMapBinder&lt;Class&lt;? extends Key&gt;, Value&gt; mapBinder = GinMapBinder .newMapBinder(binder(), new TypeLiteral&lt;Class&lt;? extends Key&gt;&gt;() { }, new TypeLiteral&lt;Value&gt;() { }); </code></pre> <p>but when i'm trying populate my map</p> <pre><code>mapBinder.addBinding(KeyImpl.class).to(Value.class); </code></pre> <p>i'm getting error: </p> <pre><code> Error injecting @com.google.gwt.inject.client.multibindings.Internal() java.lang.Class&lt;? extends my.test.gwt.gin.objects.Key&gt;: Unable to create or inherit binding: No implementation bound for '@com.google.gwt.inject.client.multibindings.Internal() java.lang.Class&lt;? extendsmy.test.gwt.gin.objects.Key&gt;' and an implicit binding cannot be created because the type is annotated. Path to required node: @com.google.gwt.inject.client.multibindings.Internal com.google.gwt.inject.client.multibindings.MapEntry&lt;java.lang.Class&lt;? extends my.test.gwt.gin.objects.Key&gt;, my.test.gwt.gin.objects.Value&gt; [com.google.gwt.inject.client.multibindings.BindingRecorder.bind(BindingRecorder.java:42)] -&gt; com.google.gwt.inject.client.multibindings.MapEntry&lt;java.lang.Class&lt;? extends my.test.gwt.gin.objects.Key&gt;, my.test.gwt.gin.objects.Value&gt; [com.google.gwt.inject.client.multibindings.BindingRecorder.bind(BindingRecorder.java:42)] -&gt; @com.google.gwt.inject.client.multibindings.Internal() java.lang.Class&lt;? extends my.test.gwt.gin.objects.Key&gt; [@Inject constructor of com.google.gwt.inject.client.multibindings.MapEntry&lt;java.lang.Class&lt;? extends my.test.gwt.gin.objects.Key&gt;, my.test.gwt.gin.objects.Value&gt;] </code></pre> <p>if i wont use <code>TypeLiteral</code>this will works, but i dont want class with raw type. So i'll be glad if anyone can help me to solve this issue. Thanks in advance</p>

    1. COCurious how did you get the new TypeLiteral to work. I am using guice 3 and gin 2.1.1. TypeLiteral has a protected constructor. I can't figure out how to create a type literal with my generic class as you have done.

    2. CO@ChrisHinshaw If you initialize `TypeLiteral` as anonymous class, then you can access it constructor

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.
