    <p>I have a datatable in which each row has 24 hour input fields in it. At one point of time there are more than 1000 editable input fields. I noticed that while using p:cellEditor during ajax calls primefaces is submitting the entire datatable. How can I avoid that? Please find below the code that I have, and also find the comments on each important parts in them.</p> <pre><code> &lt;!-- Fires the cellEdit event to trigger the validations to happen as user tabs out of the input box --&gt; &lt;p:ajax event="cellEdit" listener="#{renderValidator.onCellEdit}" update=":#{p:component('globalMessages')}" process="@this" /&gt; &lt;p:column id="hour1" styleClass="col-right col-90"&gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="1" escape="false"/&gt; &lt;/f:facet&gt; &lt;p:cellEditor &gt; &lt;f:facet name="output"&gt; &lt;h:outputText value="#{row.amount[0]}" escape="false"&gt; &lt;f:convertNumber maxFractionDigits="3" minFractionDigits="3" maxIntegerDigits="5" /&gt; &lt;/h:outputText&gt; &lt;/f:facet&gt; &lt;f:facet name="input"&gt; &lt;p:inputText id="hour1Input" value="#{row.amount[0]}" maxlength="10" size="10" readonly="#{row.readOnly}" onchange='PowerMeter.setPowerMeterChange()' styleClass="col-right" valueChangeListener="#{row.setDirtyFlag(true)}" &gt; &lt;!-- formats data the way its displayed --&gt; &lt;f:convertNumber maxFractionDigits="3" minFractionDigits="3" maxIntegerDigits="5" /&gt; &lt;!-- validates the input value w.r.t a custom validator --&gt; &lt;f:validator validatorId="hourlyValueValidator" for="hour1Input" /&gt; &lt;!-- javascript restricting user to input alpha numeric characters --&gt; &lt;pe:keyFilter testFunction="return PowerMeter.isValidMWH(this, c);" /&gt; &lt;/p:inputText&gt; &lt;/f:facet&gt; &lt;/p:cellEditor&gt; &lt;/p:column&gt; </code></pre>

    1. CODurng Ajax calls for validation, I would prefer just that particular input text to be passed. I tried replacing @this with the id 'hour1Input' but still in chrome I could see that whole table is getting submitted.

    2. COWhat about trying [lazy load](http://www.primefaces.org/showcase/ui/datatableLazy.jsf)? Or instead celleditor you can implement your own button. That one is not an easy job.

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.
