I have to make a webpage with jsf and primafecas, but I don't have to much experience with it. I have to change the content of the page without reloading everything( the background is quite large).
I made a menu(with toolbar) and an iframe to easily change the content (gmap, text, forms, datatable etc). I know it is one of the worst solution, but I couldn't find better.
Now I have to change the menu from the iframe, but it looks impossible, so I'd like to use a nice method instead of the iframe. I tried a few things, but nothing worked well, sometimes i got duplicate id error or nothing worked, but sometimes nothing rendered except the menu.
Now the code looks like this:
<ui:define name="menu">
<h:form id="menuForm">
<p:toolbar activeIndex="#{navigationBean.pageCount}">
<p:toolbarGroup align="right">
<p:commandButton value="menu1" action="#{navigationBean.setUrl(...)}" update=":frmContent,menuForm" />
<p:commandButton value="menu2" action="#{navigationBean.setUrl(...)}" update=":frmContent,menuForm" />
<p:commandButton value="menu3" action="#{navigationBean.setUrl(...)}" update=":frmContent,menuForm" />
<p:commandButton value="menu3" action="#{navigationBean.setUrl(...)}" update=":frmContent,menuForm"/>
</p:toolbar>
</h:form>
</ui:define>
<ui:define name="content">
<h:form id="frmContent" style="height:100%;width:100%" height="100%" width="100%">
<iframe src="#{navigationBean.url}" id="frame" frameborder="0" style="height:100%;width:100%" height="100vh" width="100%"/>
</h:form>
I need a working method to change the content or the whole page without the background.
Try using
<ui:include src="#{navigationBean.url}" />
instead of the iframe.
I've having problems trying to customize the footer on a calendar using the f:facet tag. The content in the tag is being ignored, being the default footer shown instead.
I can customise the footer using rich:calendar attributes like showApplyButton, but I think it is not possible to remove the selected date that appears on the left of Clean button ('Netejar' in the image) without adding the Apply button, which is something my customer doesn't want.
We are using RichFaces 4.3.5.Final.
Code:
<rich:calendar
value="#{YourBeanHere.yourDateHere}"
locale="es_ES">
<f:facet name="footer">
<h:panelGrid columns="3" width="100%" columnClasses="fake, width100 talign">
<h:outputText value="{selectedDateControl}" style="font-weight:bold;" />
<h:outputText value="{timeControl}" style="font-weight:bold;" />
<h:outputText value="{todayControl}" style="font-weight:bold;" />
</h:panelGrid>
</f:facet>
</rich:calendar>
Calendar sample as it is shown with the code above:
Thanks in advance for your help.
The calendar footer is not customizable (not every component is set up to use the facets). You have to put the grid under the table and hide the footer (.rf-cal-ftr) if you need to.
I would like to be able to conditionally omit a footer from a PrimeFaces panel element:
<p:panel header="some text">
<f:facet name="footer">
#{message}
</f:facet>
<!-- ... -->
</p:panel>
I hoped that the rendered attribute would work:
<p:panel header="some text">
<f:facet name="footer" rendered="#{!empty message}">
#{message}
</f:facet>
<!-- ... -->
</p:panel>
But the footer is still rendered, with empty content. It appears that facet does not have the rendered attribute: http://www.jsftoolbox.com/documentation/help/12-TagReference/core/f_facet.html.
What's the right way to do this?
I was able to solve this by swapping the facet out for an attribute. To summarize:
This works
<p:panel ...>
<f:attribute name="footer" value="#{message}"/>
<!-- ... -->
</p:panel>
But this doesn't work
<p:panel footer="#{message}">
<!-- ... -->
</p:panel>
Neither does this
<p:panel ...>
<f:facet name="footer">#{message}</f:facet>
<!-- ... -->
</p:panel>
Nor this
<p:panel ...>
<f:facet name="footer">
<h:outputText value="#{message}" rendered="#{!empty message}"/>
</f:facet>
<!-- ... -->
</p:panel>
by "works" I mean:
"renders no footer — not just an empty footer — when #{message} is empty or null; otherwise, correctly renders the footer with the specified text."
PrimeFaces forum thread on this issue
You could declare a ui:param and let the template check the param while renderring.
The facet in the template could then be declared as:
<f:facet name="#{hideFooter == null or not hideFooter ? 'footer' : ''}">
#{message}
</f:facet>
Any page can then declare this param
<ui:param name='hideFooter' value='#{some rule}' />
and set the appropriate rule for the param. For any page that does not declare the param, the footer will be displayed.
Here's what I did in trying to conditionally render a facet within a composite component.
<composite:interface>
<composite:facet name="header" required="false" />
</composite:interface>
<composite:implementation>
<p:panel>
<c:if test="#{empty component.facets.header}" >
<f:facet id="#{cc.attrs.id}_default_header" name="header">
all sorts of stuff here
</f:facet>
</c:if>
<c:if test="#{not empty component.facets.header}">
<composite:insertFacet id="#{cc.attrs.id}_custom_header" name="header" />
</c:if>
<composite:insertChildren id="#{cc.attrs.id}_content"/>
</p:panel>
</composite:implementation>
This let's the user of the composite component supply the header facet if they want, and if they don't, we supply a default. Obviously, instead of providing a default, you could simply not do anything.
This mixes c:if in jsf controls, but we didn't see any adverse effects.
I have come across a similar issue with plain JSF. I am not sure how a <p:panel> is rendered, but if it is rendered as a table, you can try this:
First, declare a CSS-class like this:
.HideFooter tfoot {
display: none;
}
Then set that class conditionally on the panel:
<p:panel styleClass="#{renderFooterCondition ? null : 'HideFooter'}">
The footer is still rendered in the JSF-sense, but it is not displayed and does not take up any space in the page when viewed by the user-agent.
I successfully solved this problem using ui:fragment
<ui:fragment rendered="...Test...">
<f:facet name="footer">
...
</f:facet>
</ui:fragment>
works for example to conditionnaly render the footer of a primefaces datatable (the rendered attribute of the facet does not work).
Not sure how well this would work for your footer, but I had the same issue with a legend I was trying to conditionally render. I fixed it by using the rendered on anything inside the facet tag.
<p:fieldset>
<f:facet name="legend">
<h:outputText value="#{header1}" rendered="#{header1.exists}"/>
<h:outputText value="#{header2}" rendered="#{not header1.exists}"/>
</f:facet>
content
</p:fieldset>
I had difficulty trying c:if with my ui:repeat, so this was my solution. Not quite the same as your problem, but similar.
Facets are not intended to render HTML, which is why it doesn't have the rendered attribute. Facets add functionality to a page. The term facet is probably a poor choice of name. It's very ambiguous.
..if the list compiled by ITworld's Phil Johnson has it right, the
single hardest thing developers do is name things.
ie.
JSF facets
A project facet is a specific unit of functionality that you can add to a project when that functionality is required. When a project facet is added to a project, it can add natures, builders, classpath entries, and resources to a project, depending on the characteristics of the particular project. JSF facets define the characteristics of your JSF enabled web application. The JSF facets specify the requirements and constraints that apply to your JSF project.
The JSF facets supply a set behaviors and capabilities to your web application.
This is a counter-answer to the answer from Ludovic Pénet.
This worked for me in <f:facet name="footer"> in selected p:column items of a p:dataTable (Primefaces 5.3):
...
Note how I have the ui:fragment inside the f:facet, not outside (not wrapping) it. It definitely completely removes the entire row when every footer facet is tested to NOT render (as far as I can tell, independent of the content within the ui:fragment).
Try with this, from primefaces web page
<p:columnGroup type="footer">
<p:row>
<p:column colspan="3" style="text-align:right" footerText="Totals:" />
<p:column footerText="your value in ajax" />
<p:column footerText="your value in ajax" />
</p:row>
</p:columnGroup>

For those who landed here trying to hide the footer, instead of header, but the syntax component.facets.footer didn't work, should try this:
<p:panel id="panelContent">
<c:if test="#{not empty cc.facets.footer}">
<f:facet name="footer" height="100%">
your content
</f:facet>
</c:if>
</panel>
Why don't you enclose the content of the footer into a panelGroup which has the rendered attribute?
This way:
<p:panel header="some text">
<f:facet name="footer">
<h:panelGroup rendered="#{!empty message}">
#{message}
</h:panelGroup>
</f:facet>
<!-- ... -->
</p:panel>
I do it in my weapp and it works, no footer is rendered.
I don't use primefaces though, I do it with h:datatable, but I think that it must works with p:panel too.
I try this solution and ok. (http://www.coderanch.com/t/431222/JSF/java/dynamically-set-panel-header-condition)
<rich:dataGrid value="#{myMB.student.list}" rendered="#{!empty myMB.student and !empty myMB.student.list}" var="st" rowKeyVar="row">
<rich:panel>
<f:facet name="header">
<h:panelGroup id="panelHeader">
<h:outputText value="Just one student" id="header1" required="true" rendered="#{!myMB.manyStudents}"/>
<h:outputText value="#{row+1}º Student" id="header2" required="true" rendered="#{myMB.manyStudents}"/>
</h:panelGroup>
</f:facet>
<rich:panel>
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.
i've got this jsf code
<f:view>
<rich:page pageTitle="My Page" markupType="xhtml">
...
<rich:panel id="content">
<a4j:include viewId="#{MyBacking.viewId}" />
</rich:panel>
and after trying a number of different ways, I've still not managed to place the following correctly in my code:
<rich:effect for="window" event="onload" type="BlindDown" params="targetId:'<different tags depending on where I place this tag>',duration:2.8" />
My aim is to have the changed element in the a4j:included part of the page change but with the effect in use. I've tried putting it in my included page, or just after the f:view and rich:page tags in the calling page but to no avail. The demo doesn't take includes into account so I'm a bit stuck. Thanks
Just target the a panel inside the rich:panel: targetId:'contentPanel'
and then
<rich:panel ..>
<h:panelGroup layout="block" id="contentPanel">
<a4j:include viewId="#{MyBacking.viewId}">
<ui:param name="targetIdParam" value="putYourTargetIdHere" />
</a4j:include>
<h:panelGroup>
</rich:panel>
