I want to export a data table in csv,pdf format in primefaces 4.0 .For that I used following code :
<p:dataTable var="valuesTable" value="#{userBean.groupResultList}"
paginator="false" id="valuesTable" resizableColumns="true"
rendered="#{not empty userBean.groupResultList}">
<p:column headerText="Group" id="grp"> #{valuesTable.groupName}</p:column>
<p:column headerText="Technical Knowledge" id="tk">
#{valuesTable.tkValue}
</p:column>
<p:column headerText="Project Management" id="pm">
#{valuesTable.pmValue}
</p:column>
<p:column headerText="Growth" id="ga">
#{valuesTable.gaValue}
</p:column>
<f:facet name="footer">
<h:commandLink>
<p:graphicImage value="/images/xml.jpeg" width="20" height="20" />
<p:dataExporter target="valuesTable" type="xml" fileName="Data_XML" />
</h:commandLink>
</f:facet>
</p:dataTable>
Data table displays correct data in each cell when I run the application.
But when I try to export it in csv or pdf format, rather then exporting actual numbers (or values of the object) it is exporting "#{valuesTable.groupName}" "#{valuesTable.tkValue}" ,"#{valuesTable.pmValue}" ,"#{valuesTable.gaValue}" for each object in csv file.
CSV file Content :
#{valuesTable.groupName} #{valuesTable.tkFormatedValue} #{valuesTable.pmFormatedValue} #{valuesTable.gaFormatedValue}
Data Table Content :
Group Name Technical Knowledge Project Management Growth
India .8 .7 1.0
I don not know why it is exporting the data table in this way..
Please Help
Thanks
I had a similar problem once with the dataTable exporter.
You have to use an outputText like this:
<h:outputText value="#{valuesTable.tkValue}"/>
inside all the column tags, in order to see the values properly.
Your column would become:
<p:column headerText="Technical Knowledge" id="tk">
<h:outputText value="#{valuesTable.tkValue}"/>
</p:column>
Replace all your columns and try that!
Hope it helps!
And also I think the headers are not ok. You have to use an f:facet tag like this:
<p:column id="tk">
<f:facet name="header">
<h:outputText value="Technical Knowledge" />
</f:facet>
<h:outputText value="#{valuesTable.tkValue}"/>
</p:column>
Now you should also see the headers in the export CSV file.
DataTable export is not working in Primefaces 4.0
Step 1: You need to add jars for exporting csv ,pdf file .
itext-1.1.4.jar
Step 2: DataExplorar.xhtml

I am trying to generate a editable datatable dynamically dependend on the resultset of an previously executed SQL-Query.
Depending on which columns would have a constant value I am trying to not render them. That part of the code works just fine, everything is displayed as i would like it to be.
My issues are with the cellEditor. I generate my datable as follows:
<p:dataTable ajax="true" var="mBT" value="#{stammdaten.bbvList}" id="meldeBearbeitungsTable" editable="true" editMode="cell" scrollable="true" scrollHeight="400" style="width:600px">
<p:ajax event="cellEdit" listener="#{stammdaten.onCellEdit}" update=":Mb:message"/>
<c:forEach var="column" items="#{stammdaten.columns}">
<p:column headerText="#{column.header}">
<f:attribute name="myCol" value="#{column}" />
<span>
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{mBT[column.property]}"></h:outputText>
</f:facet>
<f:facet name="input">
<p:inputText value="#{mBT[column.property]}">
<p:keyFilter regEx="/[0-9]/i"/>
</p:inputText>
</f:facet>
</p:cellEditor>
</span>
</p:column>
</c:forEach>
</p:dataTable>
bbvList is a List of beans with different values.
columns is a List of beans to identify the header-Texts coresponding to the respective variables.
So now the issue itself:
This is how the cellEditor looks like when i click on it:
Issue-Picture
So in that example i tried to edit the field with the value "8" in it. onCellEdit gets triggered (a System.out.println is getting printed on the console) but i cant actually change the value in the respective field.
Does have cellEdit issues with the forEach initialisition of the dataTable? If yes is there a way to fix it? Else what am i doing wrong?
Since only a specific component of the html-side of code isnt working as it should be i won't post unnecessary java-Code for now. If needed i will add that as well.
Hope someone can help :)
Turns out the attribute and/or span where the cause of the problem. Simply removing them solved the issue with the cellEdit.
following works fine :
<p:dataTable ajax="true" var="mBT" value="#{stammdaten.bbvList}" id="meldeBearbeitungsTable" editable="true" editMode="cell" scrollable="true" scrollHeight="400" style="width:600px">
<p:ajax event="cellEdit" listener="#{stammdaten.onCellEdit}" update=":Mb:message"/>
<c:forEach var="column" items="#{stammdaten.columns}">
<p:column headerText="#{column.header}">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{mBT[column.property]}"></h:outputText>
</f:facet>
<f:facet name="input">
<p:inputText value="#{mBT[column.property]}">
<p:keyFilter regEx="/[0-9]/i"/>
</p:inputText>
</f:facet>
</p:cellEditor>
</p:column>
</c:forEach>
</p:dataTable>
I want to display the selected rows of a table in a dialog box but I have an empty dialog box even if I check one or more line nothing is displayed .. I realy don't know what is the cause of my problem .. I hope there will be someone who can help me (I m a beginner in jsf2 and I just discovered primefaces I really want help thanks soo much in advance ) this is my jsf :
<p:outputLabel for="product" value="" />
<p:dataTable id="product" var="ligne" value="#{productBean.myProducts}" selection="#{productBean.selectedProducts}" style="margin-bottom:0" rowKey="#{productBean.id}">
<p:column selectionMode="multiple" style="width:16px;text-align:center"/>
<p:column headerText="Code">
<h:outputText value="#{ligne.code}" />
</p:column>
<p:column headerText="designation" >
<h:outputText value="#{ligne.title}" />
</p:column>
<f:facet name="footer">
<p:commandButton process="product" update=":form:multiProductDetail" icon="ui-icon-search" value="View" oncomplete="PF('multiProductDialog').show()" />
</f:facet>
</p:dataTable>
<p:dialog header="Products" widgetVar="multiProductDialog" modal="true" showEffect="fade" hideEffect="fade" resizable="false" width="200">
<p:outputPanel id="multiProductDetail" style="text-align:center;">
<ui:repeat value="#{prodBean.selectedProducts}" var="ligne">
<h:outputText value="#{ligne.code} -- #{ligne.title}" style="display:block"/>
</ui:repeat>
</p:outputPanel>
Did you put a
h:form
inside this page
Is there data inside selection="#{productBean.selectedProducts}" .Can you a debug point there and see or put some sysouts in the getters and setters of selectedProducts.
Can you share your product code and check if selectedProducts is null or not
system.out.println("products"+selectedProducts.get(0))
best

I am having a problem with primefaces command link.
I have two <h:form> which are not nested the link from the second <h:form> is not triggered.
<h:form>
<p:dataTable>
<p:column>
</p:column>
<p:column>
<p:commandLink onclick="dialog.show()"/>
</p:column>
</dataTable>
</h:form>
<p:dialogBox widgetWar="dialog">
<h:form>
<p:dataList value="#{bean.List}" var="var">
<p:commandLink value="#{var.name}" actionListener="#{bean.viewName(var.id)}"/>
</dataList>
</h:form>
</p:dialogBox>
The command Link from the dialog box is not working and there are no exceptions thrown.
Can any one help?
Your command Link shoud be inside <p:column>.
<p:dataList value="#{bean.List}" var="var">
<p:column>
<p:commandLink value="#{var.name}" actionListener="#{bean.viewName(var.id)}"/>
</p:column>
</p:dataList>
This is necessary in order tou have data Selection inside dataList. Related problem is here
Good evening from Sweden!
I try to get a primefaces datatable to refresh. I tried various hints and solutions but nothing is working.
The button triggers a search in the DB and if I refresh the paga manually or if I use the tables sorting-function the result is shown.
Means the code in the backing bean works. But no automatic refresh directly after the button is clicked..
The bean scope is Session.
Here is the page

EDIT
Hello and thanx for the offer to help!
As you guessed searchresult is a list and the Getter is defined by
List<sbasUserList> searchresult;
public List<sbasUserList> getSearchresult() {
return searchresult;
}
search_grp is a method of the backing bean:
public String searchgrp_user(){
//FacesContext context = FacesContext.getCurrentInstance();
ObjectContainer db = this.connBD("sms");
ObjectSet<sbasUserList> res;
this.searchresult = new ArrayList<sbasUserList>() ;
Query query=db.query();
query.constrain(sbasUserList.class);
query.descend("groupname").constrain(this.searchword).like();
query.descend("type").constrain('P').or(query.descend("type").constrain('M'));
query.descend("teacher").constrain(searchteacher).contains();
res = query.execute();
this.searchresult.addAll(res);
System.out.println(this.searchresult.size());
db.close();
return "";
}
The table is filled with the right dat if i update manually the browser. (F5) but certainly would like to have this done automatically.
Sorry folks! The glassfish server I was using wasn't setup right. It showed not all of the errors in the log file. I did a complete new setup of the whole IDE (new Eclipse, new glassfish server, thanx BalusC for the incredible tutorial!!!) and I found all errors. Now it works like it should!
