    <p>I'm using primefaces 3.5 and watching a strange datatable behavior when editing data. If I enter wrong data in 'year' field and click on the tick I get a message about mistake. But if I don't click on the tick and click on the 'Add row' button I don't get a message. Only new row is added. I expect to stay in edit mode. How to solve this problem?</p> <pre><code>&lt;h:panelGrid columns="2" cellpadding="5"&gt; &lt;h:outputText value="In cell editing" /&gt; &lt;p:dataTable id="inCellEditing" var="car" value="#{dataTableController.cars}" rowKey="#{car.name}" editable="true"&gt; &lt;p:ajax event="rowEdit" listener="#{dataTableController.onEdit}" update=":mainForm:growl" /&gt; &lt;p:ajax event="rowEditCancel" listener="#{dataTableController.onCancel}" update=":mainForm:growl" /&gt; &lt;p:column headerText="Year"&gt; &lt;p:cellEditor&gt; &lt;f:facet name="output"&gt; &lt;h:outputText value="#{car.year}" /&gt; &lt;/f:facet&gt; &lt;f:facet name="input"&gt; &lt;p:inputText value="#{car.year}"&gt; &lt;p:ajax event="blur" update="@this"/&gt; &lt;/p:inputText&gt; &lt;/f:facet&gt; &lt;/p:cellEditor&gt; &lt;/p:column&gt; &lt;p:column headerText="Name"&gt; &lt;p:cellEditor&gt; &lt;f:facet name="output"&gt; &lt;h:outputText value="#{car.name}" /&gt; &lt;/f:facet&gt; &lt;f:facet name="input"&gt; &lt;h:selectOneMenu value="#{car.name}" &gt; &lt;f:selectItems value="#{dataTableController.carNames}" var="name" itemLabel="#{name}" itemValue="#{name}" /&gt; &lt;/h:selectOneMenu&gt; &lt;/f:facet&gt; &lt;/p:cellEditor&gt; &lt;/p:column&gt; &lt;p:column headerText="Actions"&gt; &lt;p:rowEditor /&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;p:commandButton action="#{dataTableController.addRow()}" value="Add row" ajax="false"/&gt; &lt;/h:panelGrid&gt; </code></pre> <p><br/> </p> <pre><code> public class DataTableController implements Serializable { private List&lt;Car&gt; cars; private Car selectedCar; private Car[] selectedCars; private List&lt;Car&gt; selectedCarsList; private SelectItem[] carNamesOptions; public DataTableController() { cars = new ArrayList&lt;Car&gt;(CarConverter.cars.values()); } public String[] getCarNames() { return CarConverter.cars.keySet().toArray(new String[0]); } public SelectItem[] getCarNamesAsOptions() { carNamesOptions = createFilterOptions(CarConverter.cars.keySet().toArray(new String[0])); return carNamesOptions; } private SelectItem[] createFilterOptions(String[] data) { SelectItem[] options = new SelectItem[data.length + 1]; options[0] = new SelectItem("", "Select"); for(int i = 0; i &lt; data.length; i++) { options[i + 1] = new SelectItem(data[i], data[i]); } return options; } public void onEdit(RowEditEvent event) { MessageUtil.addInfoMessage("car.edit", ((Car) event.getObject()).getName()); } public void onCancel(RowEditEvent event) { MessageUtil.addInfoMessage("car.edit.cancelled", ((Car) event.getObject()).getName()); } public Car getSelectedCar() { return selectedCar; } public void setSelectedCar(Car selectedCar) { this.selectedCar = selectedCar; } public Car[] getSelectedCars() { return selectedCars; } public void setSelectedCars(Car[] selectedCars) { this.selectedCars = selectedCars; } public List&lt;Car&gt; getCars() { return cars; } public void setCars(List&lt;Car&gt; cars) { this.cars = cars; } public List&lt;Car&gt; getSelectedCarsList() { return selectedCarsList; } public void setSelectedCarsList(List&lt;Car&gt; selectedCarsList) { this.selectedCarsList = selectedCarsList; } public void addRow(){ cars.add(new Car("",0)); } } </code></pre>

    1. CODo you want it to submit the data (and cause the error message if its wrong) when you click the add row, or you want the add row button behavior to be creating a new row in edit mode already?

    3. COChanging the behavior of the buttons can cause a frustrating user experience. New Row adds a new row, submit submits, everyone expects that. New row adding new row, submitting and staying in edit mode sounds very strange. Maybe you should create your own command for "submit and add new row"... check: http://stackoverflow.com/questions/16274638 , http://stackoverflow.com/questions/9561982 and dig through the linked questions on these two.

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.
