I have a XHTML displaying rows from a dataTable having few texts columns and one image column. I have been able to export the text columns for all the records in pdf, but I am not able to export the images in the rows. I searched in lots of posts to find out a way to export the images from the rows, but failed. Please note that I am not looking for exporting a single image for header or footer, which can be handled by preProcessor attribute in the p:dataExporter tag. I found good hints/examples for exporting single image using PreProcessor in dataExport tag. The hints are working fine for me. But I was unable to find any hint/example for row-wise image export. Please help!
My technology stack:
JSF2, PrimeFaces 4.0, itext-1.1.4, JDK1.8, GlassFish Server 4
My current xhtml output given below. I need to export the green ticks and red crosses to pdf.

The PrimeFaces exporter does not export images from cells only text. You will have to write a custom PDF exporter to meet your needs.

So, I've used example from showcase of PrimeFaces https://www.primefaces.org/showcase/ui/dnd/dataTable.xhtml. That's my code:
<div class="page_content">
<div class="header">Очередь рассылок</div>
<script type="text/javascript">
function handleDrop(event, ui) {
var droppedEmail = ui.draggable;
droppedEmail.fadeOut('fast');
}
</script>
<h:form>
<p:fieldset id="availableEmailsField" legend="Доступные рассылки">
<p:dataTable id="availableEmails" var="email" value="#{emailingQueueUI.customEmails}">
<p:column style="width: 20px;">
<h:outputText id="dragIcon" styleClass="ui-icon ui-icon-arrow-4"/>
<p:draggable for="dragIcon" revert="true" helper="clone"/>
</p:column>
<p:column headerText="ID">
<h:outputText value="#{email.id}"/>
</p:column>
<p:column headerText="Название">
<h:outputText value="#{email.name}"/>
</p:column>
<p:column headerText="Заголовок">
<h:outputText value="#{email.header}"/>
</p:column>
<p:column headerText="Количество порции">
<h:outputText value="#{email.chunkSize}"/>
</p:column>
</p:dataTable>
</p:fieldset>
<p:outputPanel id="selectedEmailsField">
<p:outputPanel id="dropArea">
<h:outputText value="Переместите сюда c доступных рассылок" rendered="#{empty emailingQueueUI.customEmailQueue}" style="font-size:16px;" />
<p:dataTable id="selectedEmails" var="email" value="#{emailingQueueUI.customEmailQueue}" rendered="#{not empty emailingQueueUI.customEmailQueue}"
rowIndexVar="index">
<!--<p:ajax event="rowReorder" listener="#{emailingQueueUI.onQueueReorder}" update=":form" />-->
<p:column headerText="Номер в очереди">
<h:outputText value="#{index}"/>
</p:column>
<p:column headerText="Рассылка">
<h:outputText value="#{email.id}"/>
</p:column>
<p:column headerText="Название">
<h:outputText value="#{email.name}"/>
</p:column>
<p:column headerText="Заголовок">
<h:outputText value="#{email.header}"/>
</p:column>
<p:column headerText="Количество порции">
<h:outputText value="#{email.chunkSize}"/>
</p:column>
</p:dataTable>
</p:outputPanel>
</p:outputPanel>
<p:droppable for="selectedEmailsField" tolerance="touch" activeStyleClass="ui-state-highlight" datasource="availableEmails" onDrop="handleDrop">
<p:ajax listener="#{emailingQueueUI.onEmailDrop}" update="dropArea availableEmails" />
</p:droppable>
</h:form>
</div>
There is a problem with d&d, I can drag and drop only one element from "availableEmailsField". When I try to drop another element it removes previous element and adds the dropped one.
I think the problem is in your bean.
Make sure that you initialize customEmailQueue inside #PostConstruct method and use the proper bean scope. In this case #ViewScoped.
It seems that an update function must be setted correctly in order to work properly. I faced the same issue and discovered that the ajax inside dropable has to update all drag-drop area elements, it seems that this action solves the issue.
The solution that worked is to put inside your form an:
<h:panelGroup id="elementsPanel">
....
...
...
...
....
</h:panelGroup>
, surrounding all drag-drop elements (if you dont want a panelgroup the idea is to update all the components)
and on the dropable update this panel:
<p:droppable id="dropHandler" for="selectedTable" tolerance="touch" activeStyleClass="ui-state-highlight" datasource="myDataSource" onDrop="handleDrop">
<p:ajax listener="#{dimensionsClass.onDimensionDrop2}" update="elementsPanel" />
</p:droppable>
I hope that helps!
I am using PF 5.3, on (weblogic 11g/jsf2.0/java 1.6).
I thought the issue of not shown emptyMessage in Datatable is fixed in 5.3, but inspite of using the latest version, i still dont see the message. Below is my sample code.
<p:dataTable id="attaDt" var="fileRow" value="#{pendpaybean.selectedPayDetailsFiles}"
rowIndexVar="rowIndex"
emptyMessage="No Files Uploaded"
>
<p:column headerText="Uploaded Date"
width="15px;" style="text-align:center"
>
<h:outputText value="#{fileRow.columns[0]}" />
</p:column>
<p:column headerText="Uploaded By"
width="30px;" style="text-align:center"
>
<h:outputText value="#{fileRow.columns[3]}" />
</p:column>
</p:datatable>
Any help ?
Your code works well. NOTE I put attribute value to null for showing emptyMessage.
Your adapted code:
<h:body>
<h:form>
<p:dataTable id="attaDt" value="#{null}" var="fileRow" rowIndexVar="rowIndex" emptyMessage="No Files Uploaded">
<p:column headerText="Uploaded Date" width="15px;" style="text-align:center">
<h:outputText value="#{fileRow.columns[0]}" />
</p:column>
<p:column headerText="Uploaded By" width="30px;" style="text-align:center">
<h:outputText value="#{fileRow.columns[3]}" />
</p:column>
</p:dataTable>
</h:form>
</h:body>
I am using primefaces 3.4.2 jar. I have a datatable with four columns. In two columns I have a datalist and I want to export text showed by datalist. But when I export it, it shows the following "org.primefaces.component.datalist.DataList#1195cc3" in the pdf and xls file.

But when I export it, it shows the following
"org.primefaces.component.datalist.DataList#1195cc3" in the pdf and
xls file.
Obviously, Primefaces's data exporter use the toString() method of an object to print its "value(s)".
Suggestions :
Write a custom exporter (recommended)
Override toString() method of org.primefaces.component.datalist.DataList (not advised)
I am using PrimeFaces 3.2 and want to export a dynamically created table as an .xls file. When i click on export, nothing seems to be happening.
Export Code
<h:commandLink id="Download_Excel_Format" ajax="false">
<p:graphicImage value="/resources/Excel_Icon.jpg" height="25" width="25" />
<p:dataExporter type="xls" target="dataTable" fileName="SomeFileName"/>
</h:commandLink>
dataTable
<p:dataTable id="dataTable" var="c" value="#{databaseSearch.customerList}"
paginator="true" rows="10" paginatorAlwaysVisible="false"
paginatorTemplate="Page {CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} Rows per page {RowsPerPageDropdown}"
rowsPerPageTemplate="5,10,15,30">
<p:column>
<f:facet name="header">
<h:outputText value="Machine" />
</f:facet>
<p:commandButton id="basic" value="#{c.machine}" action="#{updateEntry.setMachine(c.machine)}" oncomplete="dlg1.show();" styleClass="ui-Machinebutton" update=":Update_Entry"/>
<p:tooltip for="basic" value="Update/Delete Database Entry" showEffect="fade" hideEffect="fade" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Company" />
</f:facet>
<h:outputText value="#{c.company}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Contact" />
</f:facet>
<h:outputText value="#{c.contact}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Phone" />
</f:facet>
<h:outputText value="#{c.phone}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="Email" />
</f:facet>
<!-- <h:outputText value="#{c.email}" />-->
<h:outputLink value="mailto:#{c.email}?Subject=Baseline Monitor Alert | Machine : #{c.machine}">#{c.email}</h:outputLink>
</p:column>
</p:dataTable>
Both the dataTable and the Export command are within one form, however the dataTable is in a output panel (within the form).
Form
<h:form prependId="false" id="Main_Form">
</h:form>
Output Panel
<p:outputPanel id="panel" autoUpdate="false">
</p:outputPanel>
I even updated to PrimeFaces 3.4.2 to see if the dataExporter would work, but no avail, as far as i remember 3.2 has a bug if the dataTable generates columns dynamically, but that is not the case here right? am i doing something wrong?
dataExporter option looks much simpler, but if there is an alternative which is simple enough i am up for it.
Update
I am using a GlassFish 3.1.2.2 (build 5) & NetBeans 7.2.1, i do not get any errors, just the page refresh's, has a '#' at the end of the URL and stops, no errors means that i am not lacking any dependencies either... so i am lost here ...
Ok, i found the answer ! Tricky one though ... i had a commandButton with the ID=submit...renamed it and that did the trick !
<p:commandButton id="xsubmit" icon="ui-icon-search" title="Search Database" update="panel" actionListener="#{databaseSearch.customerList}" />
can we do a internal sorting in primeface datetable ? If i have column a ,b ,c. can i sort the column c and then internally by column b in p:dataTable.
<h:form>
<p:dataTable var="car" value="#{tableBean.carsSmall}">
<p:column headerText="Model">
<h:outputText value="#{car.model}" />
</p:column>
<p:column headerText="a">
<h:outputText value="#{car.year}" />
</p:column>
<p:column headerText="b">
<h:outputText value="#{car.manufacturer}" />
</p:column>
<p:column headerText="c">
<h:outputText value="#{car.color}" />
</p:column>
</p:dataTable>
</h:form>
Yes, you can. http://www.primefaces.org/showcase/ui/datatableSortingMultiple.jsf
P.S Don't forget pressing CTRL or Cmd :)
