Is there anyone who tried that? When it loads more panelGrid, table just duplicates them.
this picture result of that simple code block. Upper side shows how should it be rendered in a proper way but it goes wrong like at the down side.
<p:dataTable liveScroll="true" value="#{PanelController.panelList2}" var="GridPanel" scrollable="true" scrollRows="20" scrollHeight="100" rows="5">
<p:column>
<p:panelGrid>
<p:row>
<p:column>
<h:outputText value="ehehe"></h:outputText>
</p:column>
</p:row>
</p:panelGrid>
</p:column>
</p:dataTable>
If it was up to me I'd use the p:dataScroller und then use the panelgrid inside that. Take a look at this: http://www.primefaces.org/showcase/ui/data/datascroller/inline.xhtml

I am currently developing an application where the user can use a picklist to make certain associations.
I would like to display the object's attributes in different columns inside the picklist, for example the object car would display its id, year and color. However, the headerText of the column is not working. The column only displays the data but PrimeFaces seems to ignore the attribute headerText among others like sortBy. Is there any workaround? What am I doing wrong? p:column seems to work fine on a DataTable but not on a PickList and I really need to use a PickList or at least something with very similar functionalities.
Below is my code:
<p:pickList id="pickListAssociacao" value="#{associacaoPickListView.carsPickListView}" var="car" itemLabel="#{car.brand}" itemValue="#{car}">
<p:column headerText="Header1">
<h:outputText value="#{car.brand}" />
</p:column>
<p:column headerText="Header2" sortBy="#{car.year}">
<h:outputText value="#{car.year}" />
</p:column>
<p:column headerText="Header3">
<h:outputText value="#{car.year}" />
</p:column>
</p:pickList>
Thanks for your time.
I want to use a special form of grouping 'dynamic' columns. This is however not supported as stated in my other question. Using c:forEach was suggested as a possible solution
Which is correct way to use c:forEach for defining table header and colums.
My code BEFORE:
<p:dataTable id="resultTable" var="result" value="#{myBean.searchResults}" scrollable="true">
<p:columns value="#{myBean.columns}" var="column" columnIndexVar="colIndex">
<f:facet name="header" >
<h:outputText value="#{column.header}"/>
</f:facet>
<h:outputText value="#{result[column.property]}"/>
</p:columns>
</p:dataTable>
and code AFTER transformation (didn't work - table is not displayed):
<p:dataTable id="resultTable" var="result" value="#{myBean.searchResults}" scrollable="true">
<p:columnGroup type="header">
<p:row>
<c:forEach items="#{myBean.columns}" var="column">
<p:column headerText="#{column.header}"/>
</c:forEach>
</p:row>
</p:columnGroup>
<c:forEach items="#{myBean.columns}" var="column" >
<p:column>
<h:outputText value="#{result[column.property]}"/>
</p:column>
</c:forEach>
</p:dataTable>
PrimeFaces version 3.4.1
The "by the book" way to create dynamic columns would be to use the "Dynamic Columns" feature of the data table.
Any way, I did something very similar to what you are trying to do in the past, using c:forEach. The only difference was that I was not using p:columnGroup at the same time.
So, code like
<p:dataTable id="resultTable" var="result" value="#{myBean.searchResults}" scrollable="true">
<c:forEach items="#{myBean.columns}" var="column" >
<p:column headerText="#{column.header}">
<h:outputText value="#{result[column.property]}"/>
</p:column>
</c:forEach>
</p:dataTable>
should really work. When you do this way, you add p:column objets in the component tree before the p:datatable analyze the tree. So, this does the trick.
Beware that this can lead to problems in edge, ajax cases. So, if you can, just stick to the built-in dynamic columns feature.
I have a setup in a view, where I display datatables dynamically. That is happening inside a p:accordion-Element, which is generating the tabs dynamically (and therefore the datatables inside).
The user now has the possibility (well, should have..) to add, edit and remove objects to the datatable and therefore to the object that is represented by the tab.
The add- and edit-functions work via dialogs. After successful adding or editing I want to update the datatable containing the data.
If I update the whole accordion-panel I lose the focus on the current tab which is really bad for the user-experience, especially because the other sub-pages of the project always only update the datatable.
After some googling I found out that I can't generate the IDs of JSF-components dynamically, what would make the whole thing a process of minutes.
I also do not have any index I could use to "cheat" and save in my backing-bean when I open the dialog.
I also found out that I could work-around this issue by using JSTL but this is prohibited due to a limited set of allowed languages.
The current setup looks like this:
<p:accordionPanel id="academicYearAccordionPanel"
value="#{academicYearAndClassController.academicYears}"
var="academicYear" multiple="true" dynamic="true" activeIndex="-1"
style="width:100%;">
<p:tab id="academicYear-#{academicYear.academicYear}" title="Jahrgang - #{academicYear.academicYear}">
<p:outputPanel style="float:right">
<p:commandButton value="Löschen" icon="ui-icon-close"
actionListener="#{academicYearAndClassController.setAcademicYear(academicYear)}"
process="#this"
oncomplete="PF('wConfirmAcademicYearDelete').show();">
</p:commandButton>
</p:outputPanel>
<p:spacer style="height:50px;" />
<p:separator />
<!-- Tabcontent -->
<p:outputPanel>
<p:outputPanel style="float:right">
<p:commandButton value="Hinzufügen" icon="ui-icon-plusthick"
actionListener="#{academicYearAndClassController.setAcademicYear(academicYear)}"
process="#this"
oncomplete="PF('wAddSchoolclassDialog').show();">
</p:commandButton>
</p:outputPanel>
<h:panelGrid columns="2">
<h:outputText
value="Klassen des #{academicYear.academicYear}. Jahrgangs" />
<p:spacer style="height:50px;" />
</h:panelGrid>
<p:dataTable emptyMessage="Keine Klassen vorhanden"
id="schoolclassTable"
var="schoolclass"
selection="#{academicYearAndClassController.schoolclass}"
value="#{academicYearAndClassController.getSchoolclasses(academicYear)}"
selectionMode="single" rowKey="#{schoolclass.name}"
scrollable="true" scrollHeight="500">
<p:column headerText="Name">
<h:outputText value="#{schoolclass.identifier}" />
</p:column>
<p:column headerText="Klassenlehrkraft">
<h:outputText
value="#{schoolclass.teacher.name} (#{schoolclass.teacher.symbol})" />
</p:column>
<p:column headerText="Klassenraum">
<h:outputText
value="#{schoolclass.room.name} (#{schoolclass.room.locationName})" />
</p:column>
</p:dataTable>
</p:outputPanel>
</p:tab>
</p:accordionPanel>
I want to update the element with the ID schoolclassTable. How can I achieve this?
I'm using Primefaces 4.0. I'm starting to get a feel for this, but can't seem to get it straight, and the documentation hasn't helped much with this specific question.
Can someone explain the relationship between these two components? Does <p:rowExpansion> dictate what is displayed when <p:rowToggler> is used?
Don't know what confuses you, but inside <p:rowExpansion> you put the content which will be displayed when <p:rowToggler> is clicked. You've probably seen examples, but I'll put one here just for reference (taken from primefaces showcase)
<p:dataTable var="car" value="#{dtBasicView.cars}">
<f:facet name="header">
Expand rows to see detailed information
</f:facet>
<p:column style="width:16px">
<p:rowToggler />
</p:column>
<p:column headerText="Id">
...
</p:column>
<p:rowExpansion>
<p:panelGrid columns="2" columnClasses="label,value" style="width:300px">
<f:facet name="header">
<p:graphicImage name="demo/images/car/#{car.brand}-big.gif"/>
</f:facet>
<h:outputText value="Id:" />
<h:outputText value="#{car.id}" />
...
</p:panelGrid>
</p:rowExpansion>
</p:dataTable>
This is a clumsy question!!! :)
Can this be made possible somehow? Can <p:dataTable> (whatever lazily loaded or otherwise) be updated without updating its headers (The contents (rows) inside the table along with the footer should be updated without updating the table headers)?
Updating of <p:dataTable> may be triggered by any UICommand like <p:commandButton>, <p:commandLink> and alike.
Something like this can be visualized, when we edit/update rows using <p:cellEditor> in conjunction with <p:rowEditor/> in <p:dataTable> (not sure about single cell editing).
<p:dataTable id="dataTable" var="row" value="#{bean}" ...>
<p:column headerText="Header 1" sortBy="#{row.property1}" filterBy="#{row.property1}">
....
</p:column>
<p:column>
<!--They may be our own headers-->
<f:facet name="header">
Header 2
...
</f:facet>
....
</p:column>
...
</p:dataTable>
Easiest way is to use PrimeFaces Selectors (PFS) for this. This only requires the desired cell content being wrapped in another component with an ID and a style class — so that jQuery can find and collect them.
E.g.
<p:dataTable ...>
<p:column>
<f:facet name="header">...</f:facet>
<h:panelGroup id="col1" styleClass="cell">...</h:panelGroup>
</p:column>
<p:column>
<f:facet name="header">...</f:facet>
<h:panelGroup id="col2" styleClass="cell">...</h:panelGroup>
</p:column>
<p:column>
<f:facet name="header">...</f:facet>
<h:panelGroup id="col3" styleClass="cell">...</h:panelGroup>
</p:column>
...
</p:dataTable>
<p:commandButton value="update" update="#(.cell)" />
That wrapping is clumsy, yes, but that's best you can get without homebrewing a custom renderer. You can always create a <my:column> tagfile to reduce the boilerplate.
