Primefaces DataTable fires update THREE times - datatable

In the code shown below the button with update="testTable" fires Bean.getSensors call three times, but the button with update="#form" fires only one. Why?
<h:form id="form4" prependId="true">
<p:commandButton value="id" update="testTable" process="#none"/>
<p:commandButton value="#form" update="#form" process="#none"/>
<p:dataTable id="testTable" value="#{bean.sensors}"
var="sensor"
rowStyleClass="#{sensor.alarm ? 'alarm' : null}">
<p:column headerText="Name" style="min-width: 100px; width: 100px;">
<h:outputText value="#{sensor.name}"/>
</p:column>
<p:column headerText="Value" style="min-width: 100px; width: 100px;">
<h:outputText value="#{sensor.value}"/>
</p:column>
</p:dataTable>
</h:form>
Thanks for all!

This is normal. JSF and Primefaces need to call it multiple times.
If You have performance issues, use lazy loading
public List<Sensor> getSensors(){
if(sensors == null){
sensors = ejb.getSensors();
}
return sensors;
}

JSF + primefaces spinner ajax invoking other submits

I'm using ajax in spinner to call some action in backing bean.
this is my code:
<b:panel>
<p:dataTable id="orderDataTable" var="order" value="#{orderViewBean.orders}"
widgetVar="ordersDataTable" tableStyle="table-layout: auto;">
<p:column headerText="Created" filterBy="#{order.creationDate}" filterStyle="display: none"
filterMatchMode="contains">
<h:outputText value="#{order.creationDate}"/>
</p:column>
<p:column headerText="Created By" filterBy="#{order.createdBy}" filterStyle="display: none"
filterMatchMode="contains">
<h:outputText value="#{order.createdBy}"/>
</p:column>
</p:dataTable>
<b:panelGrid colSpans="4,4,4">
<b:commandButton action="#{orderViewBean.previousPage}" value="Previous"
look="primary" process="#this:uploadOrderDataPanel" styleClass="pull-left"
disabled="#{!orderViewBean.page.hasPrevious()}" type="submit">
<p:ajax immediate="true" update=":companyOrdersForm"/>
</b:commandButton>
<b:row>
<div class="text-center">
<h:outputLabel value="Page"/>
<p:spinner value="#{orderViewBean.currentPage}" size="3"
min="#{orderViewBean.page.totalPages > 0 ? 1 : 0}"
max="#{orderViewBean.page.totalPages}">
<p:ajax listener="#{orderViewBean.changePageAjax}"
update="#form" process="#this" immediate="true"/>
</p:spinner>
<h:outputLabel value="Of"/>
<h:outputText value="#{orderViewBean.page.totalPages}"/>
</div>
</b:row>
<b:commandButton action="#{orderViewBean.nextPage}" value="Next"
look="primary" process="#this:uploadOrderDataPanel" styleClass="pull-right"
disabled="#{!orderViewBean.page.hasNext()}" type="submit">
<p:ajax immediate="true" update=":companyOrdersForm"/>
</b:commandButton>
</b:panelGrid>
</b:panel>
When I put some number into spinner and hit enter, then changePageAjax is invoked (this is ok) and also orderViewBean.previousPage (this is not ok). Can I avoid invoking other actions?
Add a partialSubmit="true" attribute on the relevant ajax tags.. From the PF documentation:
PartialSubmit reduces network traffic by only adding the partially processed components to the ajax request post. For big pages with many input components, partialSubmit is extremely useful as it leads to more lightweight requests. Compare the Post Data displayed by the logger for the difference.

The commandButton should update a dataTable. I have just moved from Prime 3.5 to 5.1 and among other problems I managed to figure out, there is this one that's realy annoying. It was working on Prime 3.5.
To be more specific about what is going wrong here: The action is fired normaly, the data is inserted correctly, but the dataTable is no longer updated. It is the very same code I was using yesterday with Prime 3.5, but now, using Prime 5.1 the dataTable does not refresh anymore.
Any ideas ? Thanks
use : before id
Remember
if you make a dialog
Before dialog old form tag should be close
then dialog content should be placed into another form.
use :dialogid, :dialogFormId

JSF PrimeFaces / Ajax rendering to Datable fails to add items to the list

I am trying to user a form in 'panelGrid' to render values in a dataTable using <f:ajax>. However, when submitting using the <h:commandButton> the values sent are not displayed in the dataTable. I am not getting a stack or any console errors in the browsers.
This is the my xhtml (Simplified):
Product Catalog:
<p:tabView id="tabView" style="width: 65%" >
<p:tab id="books" title="Books">
<p:dataGrid var="book" value="#{saleBean.productList}" columns="3"
rows="9" paginator="true" paginatorTemplate="{CurrentPageReport}
{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink}
{LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="3,6,9">
<h:form id="product" >
<p:panel header="#{book.name}" style="text-align: center">
<h:panelGrid columns="1" style="width: 65%">
<!-- Add Book Images here -->
<h:outputText value="#{book.price}"/>
<h:outputLabel value="Dct (in dollars): " />
<h:inputText id="discount" value="#{saleBean.item.unit_discount}" style="width: 50%" />
<p:commandButton value="Add to Cart" update=":dataTableForm:sc"
action="#{saleBean.doAddItem}"/>
</h:panelGrid>
</p:panel>
</h:form>
</p:dataGrid>
</p:tab>
<p:tab id="arts" title="Art / Various">
<!-- Art Products to be added here -->
</p:tab>
<p:tab id="other" title="Other">
<!-- Various Products to be Added here -->
</p:tab>
</p:tabView>
<hr/>
<h1>Shopping Cart</h1>
<hr/>
<h:form id="dataTableForm">
<p:dataTable id="sc" value="#{saleBean.sd}" var="item" style="width: 60%">
<p:column>
<f:facet name="header">
<h:outputText value="Product"/>
</f:facet>
<h:outputText value="#{item.product_fk}"/>
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Quantity"/>
</f:facet>
<h:outputText value="#{item.quantity}"/>
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Unit Price"/>
</f:facet>
<h:outputText value="#{item.unit_Cost}"/>
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Unit Discount"/>
</f:facet>
<h:outputText value="#{item.unit_discount}"/>
</p:column>
</p:dataTable>
</h:form>
</h:body>
This the bean (Simplified):
public String doAddItem()
{
item.setUnit_Cost(product.getPrice());
item.setProduct_fk(product);
item.setQuantity(1);
sd.add(item);
return "productCatalog";
}
According to PrimeFaces documentation :
http://www.primefaces.org/docs/vdl/3.4/primefaces-p/commandButton.html
Your actionListener="#{saleBean.doAddItem}" must use a function corresponding to that :
public void doAddItem(ActionListener event)
{
// do your stuff
}
To use action here is an example :
action="#{saleBean.doAddItem}"
public String doAddItem(void)
{
item.setUnit_Cost(product.getPrice());
item.setProduct_fk(product);
item.setQuantity(1);
sd.add(item);
return "productCatalog";
}
Try to use only pf components when you can eg p:datatable. Replace the button with a p:commandButton and use process and update instead of f:ajax.
Also maybe it will by better to include the p:datatable in the form too.
