I have a datatable, where I add rows dynamically (a button click), and let users edit those rows with primefaces cell editing.
I want to add validation for the cells, however, the validation does not occur when the input texts (in the cell) are pristine.
In order for the validation to work, the user have to actually write something in the input text (make it dirty), then deletes it, only then the validation (required for this case) will be kicked-in.
example code:
<f:view>
<p:growl autoUpdate="true"/>
<h:form>
<p:commandButton value="add row" update="table" action="#{myBean.addRow}"/>
<p:dataTable value="#{myBean.users}" var="var" id="table" editMode="cell" editable="true">
<p:column headerText="Quantity">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{var.name}"/>
</f:facet>
<f:facet name="input">
<p:inputText value="#{var.name}" required="true">
<f:validateRequired />
</p:inputText>
</f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
<p:commandButton value="submit" action="#{myBean.submit}"/>
</h:form>
</f:view>
Using primefaces 5.3 and JSF 2.2.
Update:
This bug is fixed since version 6.2

I have problem with a primefaces datable, I have a filter on a column and before to filter the result my datatable is displayed properly like this:
When I choose a filter, the combobox of the filter is properly poulated:
A soon I choose the item for the filter, the results are properly filtered but I have a display of the datatable like this:
I just see the results who should be display in a datatable but the table is gone.
The code seems good and I don't see where is the problem:

Did you already meet this issue with the rendered of a datable? Any idea how to fix it?
Effectively, your title and first sentence are not correct. It is not a bug in the datatable but a 'bug' in your code. You should not use autoupdate="true" on the p:outputPanel in this case. It updates all its content on each ajax update that happens inside it, including an ajax update during filtering. This latter also updates the datatable which means two conflicting updates. Off-topic: If you'd created a Minimal, Complete, and Verifiable example , you'd have found this out during removal of code.
If you have this problem when you have an ajax listener on one of the filter/page/sort/... events on the datatable and you need the autoUpdate="true" on the panel for other events in the wrapping panel, you could also prevent the autoUpdate to happen for these specific events by adding a ignoreAutoUpdate="true" to the specific events. So e.g.
<p:ajax event="filter" ignoreAutoUpdate="true" ... />
I have two calendar controls and one command button. basically i want to give a range of date to pick the data from the database and then when i press the command button the datatable is displayed in the dialog box, the problem is java bean class is working it is loading the exact data which i want, but the datatable is not refreshing with command button click
my code is given;
<h:form id="form" >
<p:calendar value="#{calendarBean.dateFrom}" id="calFrom" pattern="yyyy-mm-dd">
<p:ajax event="dateSelect" listener="#{calendarBean.handleDateSelectFrom}" />
</p:calendar>
<p:calendar value="#{calendarBean.dateTo}" id="calTo" pattern="yyyy-mm-dd">
<p:ajax event="dateSelect" listener="#{calendarBean.handleDateSelectTo}" />
</p:calendar>
<p:commandButton value="Submit" action="#{calendarBean.submit()}" update="fTable" onclick="aDlg.show()">
<f:ajax render=":form:fTable" execute="#form"></f:ajax>
</p:commandButton>
<p:dialog id="aDialog" header="Filter List" widgetVar="aDlg"
modal="true" showEffect="explode"
hideEffect="explode" >
<p:panel id="pnl">
<p:dataTable id="fTable" value="#{calenderBean.list}" var="row" >
<p:column headerText="ID">
<h:outputText value="#{row.ID}"/>
</p:column>
<p:column headerText="Name">
<h:outputText value="#{row.Name}"/>
</p:column>
<p:column headerText="Time">
<h:outputText value="#{row.Time}"/>
</p:column>
<p:column headerText="User">
<h:outputText value="#{row.userName}"/>
</p:column>
</p:dataTable>
</p:panel>
</p:dialog>
</h:form>
kindly guide me regarding this issue
First thing to do, is remove the f:ajax, it's not working good with Primefaces. Also the update attribute should do everything.
This said, I have the very same code as yours which is working good.
If removing f:ajax is not working, try to check your managed bean scope (May be it's of request scope and data is re-initialized with every request)
Try Updating the dialog instead.
update="fTable"
I want a table with in-line editing option in datatable. I am able to write full code but when i am clicking on edit button, the value which i am getting from event object from server side is same as old. I am not getting new values.
how to get new values from event object.
<p:dataTable id="dataTable"
var="osList"
value="#{WLMPortalViewController.allOSInfo}" rowKey="#{osList.osName}"
paginator="true" rows="5"
paginatorPosition="bottom"
editable="true" >
<p:ajax event="rowEdit" update="#this" listener="#{WLMPortalDataController.saveOSData}"/>
<p:column headerText="Options" >
<p:rowEditor />
</p:column>
<p:column headerText="Version" >
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{osList.osVersion}" />
</f:facet>
<f:facet name="input">
<p:inputText id="inputosVer" required="true" requiredMessage="* Version can't Empty." value="#{osList.osVersion}" />
</f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
and my server side code look like this
public void saveOSData(RowEditEvent event){
System.out.print(event.getObject());
}
Hi
I have made an ajax call using primefaces [p:ajax]. The call to the listener was successful and it returned the required values. To update these properties in xhtml, I have checked the DOM source, to find out the exact ID of the column, using which the column or property would be updated. But, in this case the fields are not getting the values.
The code I used in this case is
<p:dataTable id="table1" var="recepit" rowIndexVar="rowIndex" value="#{ReceiptDetailsBean.iterativeList}" scrollable="true" height="120px" styleClass="leftTable">
<p:column style="background-color: #EFF2F9">
<f:facet name="header">
<h:outputText value="SL NO" />
</f:facet>
<h:outputText value="#{rowIndex+1}" />
</p:column>
<p:column >
<f:facet name="header">
<h:outputText value="Buss." />
</f:facet>
<h:selectOneMenu id="selectOneCb" value="#{ReceiptDetailsBean.bussCode}" >
<f:selectItem itemLabel="V_BUSS_CODE" itemValue=""/>
<f:selectItems value="#{ReceiptDetailsBean.rdetails}" var="model" itemLabel="#{model.buss}" itemValue="#{model.buss}"/>
<p:ajax update="mainForm:table1:#{rowIndex}:receiptCode, mainForm:table1:#{rowIndex}:referenceType" actionListener="#{ReceiptDetailsBean.obtainReceiptDatabasedOnBussCode}" event="change"/>
</h:selectOneMenu>
</p:column>
<p:column id="receiptCodeCol">
<f:facet name="header">
<h:outputText value="Receipt Code" />
</f:facet>
<h:inputText value="#{ReceiptDetailsBean.receiptCode}" id="receiptCode" style="font-family: verdana;font-size: 10px;width:80px;height:15px" />
</p:column>
<p:column id="receiptTypeCol">
<f:facet name="header">
<h:outputText value="Ref Type" />
</f:facet>
<h:inputText value="#{ReceiptDetailsBean.receiptType}" id="referenceType" style="font-family: verdana;font-size: 10px;width:80px;height:15px"/>
</p:column>
</p:dataTable>
</div>
</p:tab>
<p:tab title="Print">
</p:tab>
</p:tabView>
</h:form>
The id from the DOM view source was table1:0:receiptCodeHotKey:receiptCode
What would be the problem for the data to not get populated in the field.
I think the source of the problem is your usage of h:form. You don't need to put it around each single input element. Put one h:form around the datatable and then check again the generated ids.
Then it should be something like (example for first row with rowindex 0):
formId:table1:0:receiptCode
I have tried making an ajax call for a selectOneMenu using JSF 2 and primefaces 2.2. The actionListener method is being called. But the columns I specified in the update attribute are not getting updated. When I refersh the page, I could find the updated values. Please help me out in this.
The code I used was
<h:form id="mainForm" prependId="false">
<p>
<p:tabView>
<p:tab title="Receipt">
<p:dataTable id="table1" var="recepit" rowIndexVar="rowIndex" value="#{ReceiptDetailsBean.iterativeList}" scrollable="true" height="120px" styleClass="leftTable">
<p:column style="background-color: #EFF2F9">
<f:facet name="header">
<h:outputText value="SL NO" />
</f:facet>
<h:outputText value="#{rowIndex+1}" />
</p:column>
<p:column >
<f:facet name="header">
<h:outputText value="Buss." />
</f:facet>
<h:selectOneMenu id="selectOneCb4" value="#{ReceiptDetailsBean.bussCode}" >
<f:selectItem itemLabel="V_BUSS_CODE" itemValue=""/>
<f:selectItems value="#{ReceiptDetailsBean.rdetails}" var="model" itemLabel="#{model.buss}" itemValue="#{model.buss}"/>
<p:ajax update="table1:#{rowIndex}:receiptCode, table1:#{rowIndex}:referenceType" actionListener="#{ReceiptDetailsBean.obtainReceiptDatabasedOnBussCode}" event="change"/>
</h:selectOneMenu>
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Receipt Code" />
</f:facet>
<h:inputText value="#{ReceiptDetailsBean.receiptCode}" id="receiptCode" style="font-family: verdana;font-size: 10px;width:80px;height:15px" onkeypress="return showForhotKey(event,'#{rowIndex}');"/>
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Ref Type" />
</f:facet>
<h:inputText value="#{ReceiptDetailsBean.receiptType}" id="referenceType" style="font-family: verdana;font-size: 10px;width:80px;height:15px" onkeypress="return showForhotKey(event,'#{rowIndex}');"/>
</p:column>
</p:dataTable>
</p:tab>
<p:tab title="Print">
</p:tab>
Try f:ajax instead of p:ajax and re-render the whole form to get closer to the problem source :
<h:selectOneMenu id="selectOneCb4" value="#{ReceiptDetailsBean.bussCode}" >
<f:selectItem itemLabel="V_BUSS_CODE" itemValue=""/>
<f:selectItems value="#{ReceiptDetailsBean.rdetails}" var="model"
itemLabel="#{model.buss}" itemValue="#{model.buss}"/>
<f:ajax render="#form"
listener="#{ReceiptDetailsBean.obtainReceiptDatabasedOnBussCode}"/>
</h:selectOneMenu>
This should work as stated in my answer to your previous question.
Partial updates of dataTables and ajax updates of dataTables triggered from a component within the dataTable are not working in the 2.2 version of Primefaces. This is a known bug that may have been resolved in version 3.
One suggestion you can try is to use a single form for each dataTable and only update elements from within that one form.
