I am trying to create a datatable that displays a blockUI whenever it is busy, and I have been mostly successful. It now grays out and shows "Loading..." whenever I click either of two commandButtons, sort the datatable by clicking on a header, or page through the datatable. You can see the code for it below.
The problem is that after I have used one of the commandButtons (which runs an ajax update on the blocked element), subsequent actions do not trigger the blockUI (until I refresh the page). For example:
Load page
Click a datatable header - blockUI appears until table is finished sorting
Click one of the datatable page navigation buttons - blockUI appears until the page is loaded
Click one of the commandButtons - blockUI appears until the button's actionListener has finished
Click a datatable header - table sorts, but blockUI does not appear.
Click one of the datatable page navigation buttons - page loads, but blockUI does not appear
Click one of the commandButtons - actionListener runs and table updates, but blockUI does not appear
Reload the page - everything works properly again
Changing the commandButtons' update="" attribute to ajax="false" causes the sorting/paging to always display the blockUI, but the commandButtons to never display the blockUI.
Any ideas?
<div class="buttonDiv">
<p:commandButton ... update="resultsPanel" id="submitButton" ... />
...
<p:commandButton ... update="resultsPanel" id="resetScenarioButton" ... />
</div>
<p:panel header="Results Grid" id="resultsPanel">
...
<p:dataTable ... id="VAResults" ... >
...
</p:dataTable>
....
</p:panel>
<p:blockUI block="resultsPanel" trigger="submitButton, resetScenarioButton, VAResults">
Loading...
</p:blockUI>
The trigger attribute binds jQuery listeners on the specified elements. However if you update an element the binding gets lost. I don't know if it works, but you could try moving the <p:blockUI inside the resultsPanel. I suspect that when you update the panel the blockUI gets updated too and thus re-binding the listener to the data table.
<p:panel header="Results Grid" id="resultsPanel">
...
<p:dataTable ... id="VAResults" ... >
...
</p:dataTable>
....
<p:blockUI block="resultsPanel" trigger="submitButton, resetScenarioButton, VAResults">
Loading...
</p:blockUI>
</p:panel>
I've had the same problem and kind of simillar scenario:
<p:dataTable>
....
<p:ajax event="rowSelect" update="buttons" global="false" onstart="blockMessageButtons.show();" oncomplete="blockMessageButtons.hide();"/>
</p:dataTable>
<p:outputPanel layout="block" id="buttons">
<!-- content to be blocked -->
</p:outputPanel>
<p:blockUI block="buttons" widgetVar="blockMessageButtons"/>
The problem was that panel buttons was both updated by ajax, and blocked by blockUI. I had to divide it in two:
<p:dataTable>
....
<p:ajax event="rowSelect" update="buttons-content" global="false" onstart="blockMessageButtons.show();" oncomplete="blockMessageButtons.hide();"/>
</p:dataTable>
<p:outputPanel layout="block" id="buttons-container">
<p:outputPanel layout="block" id="buttons-content">
<!-- content to be blocked -->
</p:outputPanel>
</p:outputPanel>
<p:blockUI block="buttons-container" widgetVar="blockMessageButtons"/>
#siebz0r already provided the explanation why blockUI stops working when a component is updated.
I am using a one blockUI element in the template for all other pages and thus don't want to include more blockUI elements.
If the blockUI element is updated as well one does not need to move the blockUI inside the component that will be updated.
Here is an example:
<p:panel id="surroundingPanel">
...
<p:commandButton value="ButtonName" styleClass="blockUi"
action="actionToBeExecuted" update=":surroundingPanel :blockUiBinding" />
</p:panel>
<p:outputPanel id="blockUiBinding">
<p:blockUI block=":elementToBeBlocked" trigger="#(.blockUi)">
Loading ...
</p:blockUI>
</p:outputPanel>
The element blockUiBinding can be located anywhere, as long as it can be updated. It is wrapping the blockUI element, because blockUI generates at least two different divs. So when the wrapping element is updated also the blockUI will be updated.

I am looking for solution that p:overlayPanel content should update it self while clicking commendButton or commendLink. But its showing blank white p:overlayPanel when i click the button. The updating with the p:overlayPanel id in that button or link. I have tried many ways nothing worked out. Is my code wrong?
Please suggest some solution.
Here is my code :
<ui:repeat id="profiles" value="#{items.lstProfiles}" var="profile">
<p:commandLink id="profileLink" value="show" update="moviePanel"
actionListener="#{dashBoardController.showProfileOverlay}"/>
<p:overlayPanel id="moviePanel" for="profileLink" hideEffect="fade"
dynamic="true" style="width:300px; height: 150px;">
<h:panelGrid columns="2">
<h:outputText value="Name : "/>
<h:outputText value="#{dashBoardController.selectedProfile.name}"/>
</h:panelGrid>
</p:overlayPanel>
</ui:repeat>
Usually dynamic="true" should do the job but some times it fails.So to update the contents inside the Overlay.
There are many ways to do this by tweaking Jquery.
Simplest one I can think of is:
Since ui:repeat generates dynamic ID for p:overlayPanels you can update by providing unique css class name from every iteration.
In Primefaces you can select a component using css class also using: #(.myclass).
And so you can update that component also:- update="#(.mystyle)"
Example:
<h:form>
<ui:repeat var="patient" value="#{dataCenter.patientList}">
<p:commandLink value="#{patient.firstName}" id="patientNameLnk" update="#(.overlay-class-#{patient.patientId})"/><br/>
<p:overlayPanel for="patientNameLnk">
<h:panelGroup styleClass="overlay-class-#{patient.patientId}">
#{patient.firstName}
#{patient.lastName}
#{patient.dob}
</h:panelGroup>
</p:overlayPanel>
</ui:repeat>
</h:form>
In the above example css class name for every h:panelGroup will be generated as overlay-class-<PATIENT_ID> so every h:panelGroup will have unique class name(if patientId is unique).
Note: Note that I'm updating h:panelGroup inside p:overlayPanel because if you update p:overlayPanel then it might start flickering(it happened to me while executing above example).
I'm having some trouble with primefaces datatables and dynamic overlay for each row.
Basically I have a main datatable containing a certain number of rows. For each row, I have a button and a linked overlay that, when clicked, shows a small datatable in the overlay (it lists the lasts changes concerning the row).
Here is the simplified code:
//the main datatable
<p:dataTable id="terminauxDataTable" var="terminalBean" widgetVar="dataTableWidgetVar" value="#{cc.attrs.listAllTerminals}"
filteredValue="#{cc.attrs.listFilteredTerminals}">
...
<p:columnGroup>
<p:row>
<p:commandButton id="changelogButton"
type="button"/>
<p:overlayPanel id="changelogPanel" for="changelogButton"
dynamic="true">
//the small datatable for each row
<p:dataTable var="changelog" value="#{terminalBean.lastChangelogs}">
<p:column headerText="#{msg['commun.changelog.table.label.date']}">
<h:outputText value="#{changelog.dateHr}">
<f:converter converterId="dateTimeConverter" />
</h:outputText>
</p:column>
... some other colums
</p:dataTable>
</p:overlayPanel>
</p:row></p:column></p:datatable>
everything works fine at first sight. When I click on any button i do get the content that I want to load. it's supposed to look like this :
http://i.stack.imgur.com/n9GrW.png
(sorry, cannot post image directly)
Problems start to arise as soon as I make any filtering od sorting on the main datatable.
If a specific button was never clicked since page load, the overlay and the contained datatable are load successfuly. It dosen't matter if I applied a filter or a sort.
If I already clicked a button at least once and then I apply a sort/filter, if I try to click again on the button the overlay is shown but is empty, there is no datatable inside.
here is an exemple of a click after a filter on a button that was clicked before :

Do you have any lead on how to address this problem ?
Thank you
Using the overlay opitimally with a datatable, requires a little different approach as can be seen in the PrimeFaces showcase of the overlayPanel
You need to put the overlayPanel outside the datatable, put a updatable container in there, e.g. an outputPanel and on the button in your column, update the panel and call the show function of the overlay panel with a specific parameter. Something like this:
<p:dataTable>
....
<p:column style="width:32px;text-align: center">
<p:commandButton update=":form:terminalDetail" oncomplete="PF('myTerminalOP').show('#{component.clientId}')" icon="ui-icon-search" title="Details">
<f:setPropertyActionListener value="#{selectedTerminal}" target="#{mySelectionView.selectedTerminal}" />
</p:commandButton>
</p:column>
</p:dataTable>
<p:overlayPanel widgetVar="myOP" showEffect="fade" hideEffect="fade" dismissable="false" showCloseIcon="true">
<p:outputPanel id="terminalDetail" style="text-align:center;">
...
</p:outputPanel>
</p:overlayPanel>
(Disclaimer: done on my phone, so typos may be there)
On latest version of primeng we can do this.
Triggering the event based on element #id. By doing the toggle from typescript, I was able to pin point the element I need to attach the overlay panel to.
HTML:
<div>
<p-table>
<--loop the data-->
<button pButton (click)="showOP($event, rowwiseData, 'button'+rowIndex)" [id]="'button'+rowIndex"></button>
</p-table>
</div>
<--outside of the table add the overlay menu-->
<p-menu #menu [popup]="true" [model]="panelData"></p-menu>
TS File:
panelData: any;
#ViewChild('menu', {static: false}) op: OverlayPanel;
<!--Call and point the event to the correct element using unique #id-->
showOverlayPanel($event: MouseEvent, rowwiseData: any, id:string) {
this.panelData = rowwiseData;
this.op.toggle($event,document.getElementById(id));
}
I am getting "Cannot find component with identifier "contentForm:tabView:form:addressDialogPanel" referenced from "contentForm:tabView:form:addressBookTable" " error. How can I update my panelGrid inside the widget?
<h:form id="form">
<p:dataTable id="addressBookTable">
<p:ajax event="rowSelect" listener="#{addressBookController.onRowSelect}"
update="contentForm:tabView:form:addressDialogPanel" oncomplete="addressDialog.show()" />
</p:dataTable>
<p:dialog id="addressDialogId" widgetVar="addressDialog">
<h:panelGrid id="addressDialogPanel" columns="2" cellpadding="4">
</h:panelGrid>
</p:dialog>
</h:form>
The main problem is that you are giving the wrong client ID of component's. Also p:tabView is a component it is not a form. When you define a h:form, it generates a standart HTML form element. And when you submit the page JSF uses POST to submit your data into backing bean. So nesting them is going to occur lot's of issues that you don't expect. You should seperate forms into sections like sideForm or searchForm or etc.
You should detect the correct client ID of your component when you try to update it. You can do this with your browser's developer settings(press f12 for chrome). Then select component with the magnifier button and give that ID into update property. Just like here:

I have a dialog that contains no content on page load and I'm dynamically setting the content of a dialog box based on the link that a user clicks on.
<p:dialog widgetVar="dlg" modal="true" id="dialog">
<p:panel id="fullArticle">
<h:outputText value="#{content.newsArticle}" escape="false" />
</p:panel>
</p:dialog>
...
...
<p:commandLink value="Read more" actionListener="#{content.getFullArticle}" onclick='dlg.show();' update=":fullArticle">
<f:attribute name="contentId" value="#{news.contentId}" />
</p:commandLink>
The problem i'm having is that when you click the "Read More" link, it shows the dialog, but the dialog is not centered on the page. If i change the udpate attribute on the commandLink to update=":dialog", the dialog flashes as if it's opening and then closing right away.
How can I update the dialog and have it be centered with dynamic content?
The onclick is executed before the ajax request. You need to open the dialog in oncomplete instead. This will be executed after the ajax request and update. The <p:dialog> is namely by default hidden unless its visible attribute evaluates true.
<p:commandLink value="Read more" actionListener="#{content.getFullArticle}"
update=":dialog" oncomplete="dlg.show()">
Unrelated to the concrete problem, are you aware that you can pass fullworthy objects as method arguments since EL 2.2? This makes the <f:attribute> and actionListener "hack" superfluous:
<p:commandLink value="Read more" action="#{content.getFullArticle(news)}"
update=":dialog" oncomplete="dlg.show()" />
I had the same problem.
Updating the dialog makes it disappear and reappear (and forget its position).
To solve it, I created a wrapper tag around the dialog content.
<p:commandLink update=":playerViewDialogHeader,:playerViewDialogContent"
oncomplete='playerViewDialogJS.show()' value='#{item.name}' />
<p:dialog id='playerViewDialog' widgetVar='playerViewDialogJS'>
<f:facet name="header">
<h:outputText id="playerViewDialogHeader" value="#{playerController.objectView.name}" />
</f:facet>
<h:form id='playerViewDialogContent'>
<!-- CONTENT GOES HERE -->
</h:form>
</p:dialog>
I am using Mojarra implementation of JSF 2.1 with Primefaces 3.2.
My problem approximately looks like this:
<p:dialog id="someDialog">
..
<h:form id="dialogForm">
<p:commandLink action=".."update=":someForm:someUIRepeat:someDataTable:someInputTextArea"/>
</h:form>
</p:dialog>
<h:form id="someForm">
<ui:repeat id="someUIRepeat" value=".." ..>
<p:dataTable id="someDataTable" value=.. >
<p:column>
<p:inputTextarea id="someInputTextarea" value=../>
<p:column>
.. here go other columns
<ui:repeat>
</h:form>
The issue is that when I click on the commandLink in the dialog the inputTextarea is not updated. However, if I write this in the update of the commandLink:
update=":someForm:someUIRepeat:someDataTable,:someForm:someUIRepeat:someDataTable:someInputTextArea"
then the whole dataTable gets updated and the inputTextarea updates as well, but the values in the fields located in other columns get erased after I click on the commandLink in the dialog.
The reason why I put dataTable inside of ui:repeat is that I need to bind a dataTable with each row of one collection and I think it's not related to my problem.
Any ideas how I can solve this problem?
Thanks in advance,
Nurzhan.
for start try this
added onclick="jQuery('#someForm:someButton').click();"(check the exact id of your hidden button) to your <p:commandLink inside the dialog
set the update to update=":someForm:someUIRepeat:someDataTable"
and add
<h:commandButton id="someButton" style="display:none">
<f:ajax execute="#form"></f:ajax>
</h:commandButton>
to <h:form id="someForm">
explanation: the purpose of the hidden button is to execute (send its values) the form to the server so that when you do call update the fields wont be erased...
