Body
<p>I want to do some crazy grouping with SelectOneRadio, so I decide to create my own custom component that allow me to specify the <code>name</code> attribute of the <code><input></code> tag (as you know, same <code>name</code> means the radio buttons are in the same group). The renderer is correct, so I have a <code><input></code> that used to render like this</p> <pre><code><input name="myForm:test1" id="myForm:test1:0" value="0" type="radio"> </code></pre> <p>now render like this </p> <pre><code><input name="foo" id="myForm:test1:0" value="0" type="radio"> </code></pre> <p>However, EL stop working when I submit a form (same for h:commandButton and p:commandButton). So if I have this</p> <pre><code><xxx:selectOneRadio id="test1" value="#{myBean.selectedFood}"> </code></pre> <p>then EL work, <code>selectedFood</code> print out the corrected value, but if I put in</p> <pre><code><xxx:selectOneRadio id="test1" value="#{myBean.selectedFood}" groupId="foo"> </code></pre> <p>which will make the <code>name=foo</code> in the <code><input></code> tag. Then EL binding stop working. <code>selectedFood</code> is <code>null</code>. </p> <p>More interestingly, If I put in this</p> <pre><code><xxx:selectOneRadio id="test1" value="#{myBean.selectedFood}" groupId="myForm:test1"> </code></pre> <p>which <code>myForm:test1</code> is the correct client Id, then EL binding work again, so it does not look like it is my code that make the binding stop working. <strong>Does JSF require the <code>name</code> attribute of the <code>input</code> tag to the client id?</strong> </p>

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.
