I have created a page with primefaces where I use the Lightbox component.
I use it in a dynamic matter as I create tumbnails on the fly with a servlet call.
The first page shows up nice and the lightbox works as expected but when I load a new set of pictures for the next page the pictures are shown but when you click on it, it just shows the original picture in a new page, when I then return with the previous button and click on a a thumbnail it works as expected.
This is the jsf code:
<h:outputLabel id="curpage" value="#{pictureBean.currentPage}" />
<h:commandButton value="next" action="#{pictureBean.nextPage}" id="next">
<f:ajax render="lightBox curpage" />
</h:commandButton>
<br/>
<p:lightBox height="500px" id="lightBox">
<ui:repeat value="#{pictureBean.pictures}" var="pic">
<h:outputLink value="#{pic.url}" title="#{pic.description}">
<h:graphicImage value="#{pic.urlThumb}" style="width:100px;height:75px;"/>
</h:outputLink>
</ui:repeat>
</p:lightBox>
I fixed it myself :-) I was forgotten to add the tags between form tags.

How to show some content inside light-box of primefaces as I have to show some information about the image as no. of likes,no. of comments,and also have to provide option to post comments so on and so forth?
On xhtml page I have written this:
<p:lightBox styleClass="imagebox">
<c:forEach var="event1" items="#{event.files}" varStatus="cnt">
<h:outputLink value="#{listOfFilesForEventBean.getImage854By480ProfileUrl(event1)}" title="#{event1.location.locationName}">
<h:graphicImage value="#{listOfFilesForEventBean.getImageIconProfileUrl(event1)}"/>
</h:outputLink>
</c:forEach>
</p:lightBox>
Where files is list of image profiles that I am iterating.
And I want along with the image which is displayed on lightbox some information about the image should be displayed.
I had similar problem. If somebody is still looking for the answer here is my solution.
I did not find easy way to have some additional controls inside p:lightBox item.
Guess it assigns own JavaScript handlers to all its children and that makes a problem.
Also I had the problems with using commandButton inside ui:repeat. So I'm using my own implementation of p:lightBox and p:remoteCommand to call other actions(like post comments, delete image etc). Something like that:
<p:remoteCommand name="deleteImage" update="imagesGrid"
actionListener="#{imageBean.deleteImage}" />
<h:panelGroup id="imagesGrid">
<ui:repeat var="item" value="#{imageBean.list}">
<div class="docThumbContainer">
<div class="docPlaceholder"></div>
<div class="docThumbImage">
<h:outputLink value="/images?id=#{item.imageId}">
<h:graphicImage value="data:image/jpg;base64,#{item.thumbnail}"
alt="" />
</h:outputLink>
</div>
<div class="docThumbButtons">
<p:commandButton type="button" value="Delete"
onclick="deleteImage([{name:'imageId', value:#{item.imageId}}]);" />
</div>
</div>
</ui:repeat>
</h:panelGroup>
ImageBean:
public void deleteImage(ActionEvent event) {
ImageManager manager = getManager();
manager.deleteImage(StringUtil.parseInt(getUrlParameter("imageId"), -1));
}
Of course it is simplified replacement for p:lightBox. To show the full image in the overlay with prev/next buttons you need additional work. E.g. using p:dialog etc
I have a modal panel similar to the one below in the xhtml page.
<h:form>
<a4j:commandLink action="" rerender="panel1">
</h:form>
<a4j:outputPanel id="panel1">
<rich:modalpanel>
<a4j:form>
<h:panelgroup binding=#{mybean.panel}/>
<a4j:commandButton id="save">
</a4j:form>
</rich:modalpanel>
</a4j:outputPanel>
When I click on the a4j command link,want to display the modal panel with differrent values. It works correctly if there is no a4j:form inside the modal panel. But I want to validate and save the attributes inside the modal panel on click of save button, and hence couldnt proceed with out the form component. But strangely when I add the a4j:form, panel group stop re rendering values. Please help me to sove this.
I also tried to place both inside same form, but then it worked in a very irregular manner.
Maybe try it this way:
<h:form>
<a4j:commandLink action="" rerender="panel1">
</h:form>
<rich:modalpanel>
<h:form>
<a4j:outputPanel id="panel1">
<h:panelgroup binding=#{mybean.panel}/>
<a4j:commandButton id="save">
</a4j:outputPanel>
</h:form>
</rich:modalpanel>
Works for me with Popuppanel
when i click the button handler.toggleCreatingTheme() is called, but the outputPanel is not rendering. When i refresh the page(f5) the content of the panel is showed.
<a4j:commandButton styleClass="simple-submit-button"
action="#{handler.toggleCreatingTheme()}"
rendered="#{!handler.creatingTheme}"
value="txt"
immediate="true"
render="newThemeForm" oncomplete="initEditor()" status="statusWait" />
<a4j:outputPanel id="newThemeForm" ajaxRendered="true" rendered="#{handler.creatingTheme}">
this tags are both in a h:form tag, there is just that one h:form.
How do I let the page refreshing on his own, so rendering the panel at the moment when i click the button?
Embed newThemeForm within another a4j:outputPanel and render it instead of reRendering newThemeForm.This is because newThemeForm will not be in DOM when trying to render it as it's rendered attribute will still be false.
Like:
<a4j:outputPanel id="outerPanel>
<a4j:outputPanel id="newThemeForm" rendered="#{bean.booleanvalue}">
</a4j:outputPanel>
</a4j:outputPanel>
Render outerPanel and not the newThemeForm.
i have tried the way that AhamedMustafaM mentioned but it didnt work with me , so i searched and tried for a little while so finally i got to make it work with a workaround, here is how
<a4j:commandButton id="clear" value="Clear" action="#{handler.clearData}" immediate="true" >
<!-- dummy call just to make it work -->
<a4j:actionListener listener="#{ViewerController.test}"/>
<f:ajax render="dataGroupPanel"/>
</a4j:commandButton>
I need to render a simple link in a page that open a pdf file in a new browser window.
I wrote the following tag:
<h:commandLink target="_blank"
action="showPDF"
title="Show attached PDF"
actionListener="#{bean.doShowPDF}"
value="Show PDF">
<f:attribute name="path" value="#{bean.pdfPath}" />
</h:commandLink>
The target attribute seems to be ignored. The destination page appear over the current.
I tried with h:outputLink:
<h:outputLink target="_blank"
title="Show attached PDF"
value="/visAttached.jspx">
<f:param name="path" value="#{bean.pdfPath}" />
Show PDF
</h:outputLink>
but with the same result. The generated html , in both cases, has not the target attribute.
Where's my fault?
There is a better strategy in JSF to show a file in a new browser window?
Try the ice: versions of them: ice:outputLink, or ice:commandLink. The component showcase shows a working example (layout panels/collapsible panels has a lot of links, check the source):
<ice:outputLink target="_blank" styleClass="navPnlClpsblLnks"
value="http://icefaces.org/main/home/index.jsp">
<ice:outputText id="icefacesOrgLink" value="ICEfaces.org"/>
</ice:outputLink>
Here is my code. When I click the link Comment, a inputTextarea and commandButton suppose to appear
<h:outputLink id="link" value="javascript:void(0)">
<h:outputText value="Comment"/>
<p:effect type="fade" event="click" for="reply">
<f:param name="mode" value="'show'"/>
</p:effect>
</h:outputLink>
<h:panelGrid id="reply" style="display:none;">
<h:inputTextarea id="keyword" rows="2" />
</h:panelGrid>
</h:outputLink>
When I click on the link, nothing seem to happen, nothing appear. Any idea. I run this on Glassfish. The showcase from primeface.org is running under Tomcat.
There are two problems:
First, according to the PrimeFaces User Guide the appear effect is not supported.
Following is the list of effects supported by PrimeFaces.
blind
clip
drop
explode
fold
puff
slide
scale
bounce
highlight
pulsate
shake
size
transfer
So change the p:effect to:
<p:effect type="blind" event="click" for="reply">
<f:param name="mode" value="'show'" />
</p:effect>
Second, the generated source of the link tells the following:
<a href="javascript:void(0)">Comment<script type="text/javascript">
YAHOO.util.Event.addListener('j_idt6:j_idt7', 'click', function(e) {
jQuery(PrimeFaces.escapeClientId('j_idt6:reply')).effect('blind',{mode:'show'},1000);
});</script></a>
The client ID j_idt6:j_idt7 doesn't appear anywhere in the source. It has to be the link itself. So adding an id to the h:outputLink should fix it. Look like a bug in PrimeFaces.
