    <p>first, please forgive my ignorance and inability so use the search engine (i swear i have searched long and often but did not find any satisfying answer to this problem).</p> <p>I have a bean implementing a action-listener compatible method:</p> <pre><code>@ManagedBean(name = "myBean") @ViewScoped class Bean{ public String myAction(ActionEvent event){ ... = event.getComponent().getAttributes().get("something"); } } </code></pre> <p>Then, i have a jsf component like this:</p> <pre><code>&lt;composite:interface&gt; &lt;composite:attribute name="actionBean" required="true"/&gt; &lt;composite:attribute name="actionMethod" method-signature="void myAction(javax.faces.event.ActionEvent)" /&gt; &lt;/composite:interface&gt; &lt;composite:implementation&gt; &lt;h:form&gt; &lt;p:commandButton actionListener="#{cc.attrs.actionBean[cc.attrs.actionMethod]}"&gt; &lt;f:attribute name="something" value="somevalue" /&gt; &lt;/p:commandButton&gt; &lt;/h:form&gt; &lt;/composite:implementation&gt; </code></pre> <p>It is called something like this:</p> <pre><code>&lt;namespace:myComponent actionBean="#{myBean}" actionMethod="myAction" /&gt; </code></pre> <p>I know that this call is not working, and i wonder how to do it right!</p> <p>My main intention is that i want to have a relatively generic jsf-component (would be nice to have it reusable later), that contains a button. On click to this button i want to pass an object (no simple string! in case of string i would just use <code>action="..."</code> and pass it via <code>f:param</code>). With the <code>actionListener</code> method i take the object via <code>event.getComponent().getAttributes().get("something")</code>.</p> <p>I think the signature <code>void myAction(javax.faces.event.ActionEvent)</code> is the problem that breaks passing the related method to the component, isnt it? Is it in general possible to pass method with any argument to jsf components (and if yes, how)?</p> <p>So, i hope there is a possible solution to solve the general problem with altering the above strategy or maybe use something nice and different (in general i prefer not to use any hacks or workarounds, but like to use what is intended by the framework).</p> <p>Thanks if somebody would find the time to point me the way! In case this question already exists, would be nice to get to the related post and have this deleted.</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.
