    <p>Hey guys I'm trying to provide a possibility to inline-edit a row of a datatable with primefaces, but it doesn't seem to work properly. I can visually edit the values but when I click the save-icon, it doesn't update the changed values...</p> <p>Here is the code:</p> <p>Datatable:</p> <pre><code>&lt;p:dataTable id="ticketTypePrices" var="priceCategoryTicketType" value="#{EventInstanceController.priceCategoryTicketTypes}" editable="true"&gt; &lt;p:ajax event="rowEdit" update="@this" listener="#{EventInstanceController.onEditPrices}" /&gt; &lt;p:ajax event="rowEditCancel" listener="#{EventInstanceController.onCancelPrices}" update="@this" /&gt; &lt;p:column headerText="Preiskategorie"&gt; &lt;h:outputText value="#{priceCategoryTicketType.priceCategory.name}" /&gt; &lt;/p:column&gt; &lt;c:forEach items="#{EventInstanceController.ticketTypes}" var="item"&gt; &lt;p:column headerText="#{item.name}"&gt; &lt;p:cellEditor&gt; &lt;f:facet name="output"&gt; &lt;h:outputText value="#{priceCategoryTicketType.ticketTypes[item]}" /&gt; &lt;/f:facet&gt; &lt;f:facet name="input"&gt; &lt;p:inputText converter="bigDecimalConverter" value="#{priceCategoryTicketType.ticketTypes[item]}" style="width:50%" /&gt; &lt;/f:facet&gt; &lt;/p:cellEditor&gt; &lt;/p:column&gt; &lt;/c:forEach&gt; &lt;p:column style="width:3%"&gt; &lt;p:rowEditor /&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; </code></pre> <p>EventInstanceController.onEditPrices</p> <pre><code>public void onEditPrices(RowEditEvent event) { PriceCategoryTicketType pctt = (PriceCategoryTicketType)event.getObject(); System.out.println(pctt.getPriceCategory().getName()); for(int i = 0; i &lt; priceCategoryTicketTypes.size(); i++) { PriceCategoryTicketType pctickettype = priceCategoryTicketTypes.get(i); if(pctt.getPriceCategory().equals(pctickettype.getPriceCategory())) { for(Map.Entry&lt;TicketType, BigDecimal&gt; entry : pctt.getTicketTypes().entrySet()) { System.out.println("TicketType: " + entry.getKey().getName()); System.out.println("Price: " + entry.getValue()); } priceCategoryTicketTypes.set(i, pctt); } } } </code></pre> <p>It looks like this: <img src="https://i.stack.imgur.com/XFpOS.png" alt="Overview of the datatable"></p> <p>As you can see, the default values of each cell is 0. If I change the values (like on the picture) to f.e. 30 25 20 and hit the save-row-icon, the values will change back to 0 0 0.</p> <p>The System.out.println in the onEditPrices results to following:</p> <pre><code>INFO: TicketType: Standard INFO: Price: 0 INFO: TicketType: AHV INFO: Price: 0 INFO: TicketType: Student INFO: Price: 0 </code></pre> <p>Am I missing something? :(</p> <p>Info: I'm using primefaces version 4.0 (snapshot) but also tried and failed with stable version 3.5</p> <p>Thanks in advance, Xera</p>

    1. COI had a similar problem. It was because of value in the datatable. The list must not be changed during process. Please post the bean class.

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.

SQuiL has stopped working due to an internal error.

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