    <p>I've been digging through the archives to find an answer that might help, but nothing really seems to apply.</p> <p>I have a page in jsf with nested dataTables that is holding a list from the backing bean. The page seems to be holding the data without any issues, but when I attempt to add rows either of my dataTables using the p:collector Primefaces object, my dataTable only ever displays a single row. I am always adding an empty object to both lists.</p> <p>The objects contained in the list are custom objects that implement Serializable.</p> <p>My backing bean is ConversationScoped, and the data in the backing bean is instantiated when the conversation is started.</p> <p>Here is my main page:</p> <pre><code>&lt;ui:composition template="/templates/pageLayout.xhtml"&gt; &lt;ui:define name="pageContent"&gt; &lt;h:form id="genericWorkflowMainForm" enctype="multipart/form-data"&gt; &lt;p:panel id="actionList"&gt; &lt;div align="right"&gt; &lt;p:commandButton id="addActionButton" value="Add Action" update="actionTable" action="#{createGenericWorkflowBean.addAction}" ajax="false"&gt; &lt;p:collector id="addActionCollector" value="#{createGenericWorkflowBean.actionRow}" addTo="#{createGenericWorkflowBean.genericWorkflowData.actionGroup.actionCompletionList}"/&gt; &lt;/p:commandButton&gt; &lt;/div&gt; &lt;h:dataTable id="actionTable" var="actions" value="#{createGenericWorkflowBean.genericWorkflowData.actionGroup.actionCompletionList}"&gt; &lt;h:column&gt; &lt;h:outputLabel value="Action " /&gt; &lt;h:inputTextarea id="actionText" value="#{actions.actionRecord.actionText}" /&gt; &lt;br/&gt; &lt;p:panel id ="actioneePanel"&gt; &lt;div align="right"&gt; &lt;p:commandButton id="addApproverButton" value="Add Approver" onclick="addApprover.show()"/&gt; &lt;/div&gt; &lt;h:dataTable value="#{actions.actionRecord.actionees}" id="actioneeListValues" var="actioneeRecord"&gt; &lt;h:column&gt; &lt;h:outputText id="actioneeLabel" value="Actionee " /&gt; &lt;h:outputText id="actionee" value="#{actioneeRecord.user.user.name}" /&gt; &lt;h:outputText id="actioneeCommentlabel" value="Comments " rendered="#{actioneeRecord.user.display}"/&gt; &lt;h:inputTextarea id ="actioneeComment" value="#{actioneeRecord.userComment}" rendered="#{actioneeRecord.user.display}"/&gt; &lt;br/&gt; &lt;p:commandLink id="removeActionee" value="Remove" update="actioneeListValues" rendered="#{!actioneeRecord.user.display}"&gt; &lt;p:collector value="#{actioneeRecord}" removeFrom="#{actions.actionRecord.actionees}"/&gt; &lt;/p:commandLink&gt; &lt;/h:column&gt; &lt;/h:dataTable&gt; &lt;p:dialog id="addApprover" header="Add Approver" widgetVar="addApprover" modal="false" closable="false" resizable="false" width="250"&gt; &lt;div&gt; &lt;p:autoComplete id="autoCompleteApprover" value="#{createGenericWorkflowBean.newApprover}" /**//&gt; &lt;br/&gt; &lt;p:commandButton id="addNewApprover" title="Add Approver" value="Add" update="actioneeListValues" onclick="addApprover.hide()" ajax="false" action="#{createGenericWorkflowBean.addApprover()}"&gt; &lt;p:collector value="#{createGenericWorkflowBean.newApprover}" addTo="#{actions.actionRecord.actionees}"/&gt; &lt;/p:commandButton&gt; &lt;/div&gt; &lt;/p:dialog&gt; &lt;/p:panel&gt; &lt;/h:column&gt; &lt;/h:dataTable&gt; &lt;/p:panel&gt; &lt;/h:form&gt; &lt;/ui:define&gt; &lt;/ui:composition&gt; </code></pre> <p>Below are the parts of my backing bean that relate to the p:collector adding and removing portions of the list.</p> <pre><code>@Named @ConversationScoped public class CreateGenericWorkflowBean extends WorkflowBean { @Inject Conversation conversation; private Actionee newApprover; private ActionCompletionRecord actionRow = new ActionCompletionRecord(); private Actionee actioneeRow = new Actionee(); public GenericWorkflowData getGenericWorkflowData() { return (GenericWorkflowData) getData(); } public void addApprover() { setNewApprover(new Actionee()); } public void addAction() { actionRow = new ActionCompletionRecord(); } } </code></pre> <p>I am still learning JSF and Primefaces, so I do not know if I've done something that will just never work. </p> <p>Any help would be greatly appreciated.</p> <p>Matt Tatham</p>

    1. COThat's way too much code. Please isolate the problem in smallest possible but complete single XHTML page and single backing bean. For example, are the `<ui:define name="windowTitle">` tag and the `style="border:none"` attribute of the `<p:dataTable>` absolutely necessary in order to reproduce exactly the same problem? No? Just omit it. The same applies to all of those other unnecessary tags, attributes, properties, etc. Provide the smallest possible code containing **only** the code which is absolutely necessary to reproduce the problem ourselves by just copypasting and running the code.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
