I am using Primefaces 6.1 and if I do this in a plain xhtml page, it actually works fine. However, my problem is that I need to adopt the corporate look and feel and I am not enough of a CSS guru to know where to start debugging the issue that results from the inherited styles that cause the carousel to render all content in a list on the first "page", clicking on the other tabs shows empty content. I am trying to have each tab contain an iframe so I though that might be the problem. So, I tried simply using a simple example, slightly modified from the primefaces showcase:
<p:carousel numVisible="1" headerText="Tabs" style="margin-bottom:0" >
<p:tab title="Content I">
<h:panelGrid columns="1" cellpadding="10">
<h:outputText
value="content 1" />
</h:panelGrid>
</p:tab>
<p:tab title="Content II">
<h:panelGrid columns="1" cellpadding="10">
<h:outputText value="Content 2" />
</h:panelGrid>
</p:tab>
<p:tab title="Content III">
<h:panelGrid columns="1" cellpadding="10">
<h:outputText value="Content 3" />
</h:panelGrid>
</p:tab>
</p:carousel>
However, the output still gets rendered like this...

How do I get it to use the proper style shown in the Primefaces showcase and/or debug the problematic inherited CSS from the corporate CSS templates? Is there a way to force the standard primefaces function local to my application that would override the inherited issues?
I am working with javaEE, and for my project i used TreeTable and BlockUI to block this table, but i want to make a button appear even if it is blocked
<p:blockUI block=":form:treeTable" widgetVar="tbd" blocked="#{ManagedBean.condition}" />
<h:form id="form">
<p:treeTable id="treeTable" ... >
<f:facet name="header">
<p:commandButton value="SomeAction" actionListener="#{ManagedBean.someAction}" update=":form"/>
</f:facet>
in my example i want to make my commanbutton appear as available even if i use BlockUI
thantk you
This is not a functional problem but a design problem.
As is, the CommandButton is part of the TreeTable, so the CommandButton must be blocked if the TreeTable is blocked.
For sure Raziels answer will work, but a clean solution would be to move the button out of the TreeTable.
<h:form id="form">
<p:commandButton
value="SomeAction"
actionListener="#{ManagedBean.someAction}"
update=":form"
/>
<p:treeTable
id="treeTable"
...
/>
<p:blockUI
block=":form:treeTable"
widgetVar="tbd"
blocked="#{ManagedBean.condition}"
/>
</h:form>
I already Solved this problem by using z-index:99999 inside a style tag
so your code should be like :
<p:blockUI block=":form:treeTable" widgetVar="tbd" blocked="# {ManagedBean.condition}" />
<h:form id="form">
<p:treeTable id="treeTable" ... >
<f:facet name="header">
<p:commandButton value="SomeAction" style="z-index: 99999" actionListener="#{ManagedBean.someAction}" update=":form"/>
</f:facet>
I have some weird issue with datatable selection (most likely i'm doing something wrong).
Idea is simple - datatable with selection and a dialog to edit the records. The problem is that if i use <h:inputText> tag (or <p:inputText>) it appears to be blank, though the object in the backing bean (indicatorBean.indicator.code) contains data. Interestingly if i put <h:outputText> instead of input the data is shown.
here are contents of my body
<!-- language: xml -->
<h:body>
<h:form id="form">
<p:growl id="messages" showDetail="true"/>
<p:dataTable id="indicatorsTable" var="ind"
value="#{indicatorBean.indicators}"
selectionMode="single"
selection="#{indicatorBean.indicator}"
rowKey="#{ind.id}">
<p:column headerText="Name" style="width:125px">
#{ind.name}
</p:column>
<p:column headerText="Code" style="width:125px">
#{ind.code}
</p:column>
<f:facet name="footer">
<p:commandButton id="viewButton" value="View"
icon="ui-icon-search" update=":form:display"
oncomplete="indDialog.show()"/>
</f:facet>
</p:dataTable>
<p:dialog id="dialog" header="Indicator Detail"
widgetVar="indDialog" resizable="false"
width="400" showEffect="fade" hideEffect="fade">
<h:panelGrid id="display" columns="2" cellpadding="4">
<h:outputText value="Code:"/>
<!-- PROBLEM IS HERE -->
<h:inputText value="#{indicatorBean.indicator.code}"/>
<h:outputText value="Name:"/>
<h:outputText value="#{indicatorBean.indicator.name}"/>
</h:panelGrid>
<p:commandButton value="Save" onclick="indDialog.hide()"/>
<p:commandButton value="Cancel" onclick="indDialog.hide()"/>
</p:dialog>
</h:form>
</h:body>
Backing bean is nothing other that accessors.
Another thing i spotted is if i replace el expression in <h:inputtext> with a static text (like <h:inputText value="static text"/>), it is shown.
Here are some pictures:
Dialog with inputtext
Dialog with outputtext
Dialog with static text
primefaces 3.4
The problem as you seem to have already figured out is that you are placing the dialog itself inside of a form. This is an issue because of the way the jQuery dialog control works, which is the client side foundation of the Primefaces dialog. Essentially it will move DOM elements associated with the dialog elsewhere, possibly outside of the form that you intend to enclose it.
This problem can be easily solved by putting the dialog outside of the form, and putting a form inside of the dialog body instead.
<p:dialog id="dialogId" ...>
<h:form id="dlgForm">
....
</h:form>
</p:dialog>
In this way when jQuery UI moves the dialog control elsewhere in the DOM, the contents of that DOM, including the form come with it.
I have a problem are that when I try update a component that not are in same xhtml.
Somebody know how to do?
thx
PD: im using primefaces 3.2
Sorry for my english
I think that I dnot explain very well.
I have a xhtml father with tis structure:
<h:panelGrid id="tabla">
<h:form id="formTripu" prependId="false">
<h:panelGrid id="fichaTripulante">
<ui:include src="path1" />
<p:spacer height="5px" />
<p:tabView dynamic="false" cache="true">
<p:tab title="#{bundleTrip.datosAdministrativos}">
<ui:include
src="path2" />
</p:tab>
<p:tab title="Datos Operativos ">
<ui:include
src="path3" />
</p:tab>
I wish to do are when for example in path1 I use a h:selectBooleanCheckbox like:
<h:selectBooleanCheckbox inmediate="true" id="checkExt"
value="#{bean.Obj.field}">
<f:ajax render="estadoTripu"
actionListener="#{bean.method}" />
</h:selectBooleanCheckbox>
estadoTripu are in path2 (otherxthml but in same form).
<p:panel>
<h:panelGrid id="datos" columns="5">
<p:column>
<h:selectOneMenu id="estadoTripu"
value="#{bean.Obj.Field2}">
<f:selectItems
value="#{bean.list}" var="item"
itemValue="#{item.id}" immediate="true"
itemLabel="#{item.desc}">
</f:selectItems>
</h:selectOneMenu>
</h:panelGrid>
</p:column>
</h:panelGrid>
</p:panel>
Witch is paht in render o f:ajax????
thx everyone
try this: (Its a trick I learned from BalusC :) )
add binding="#{components.mySelecOneMenu}" to your h:selectOneMenu
<h:selectOneMenu binding="#{components.mySelecOneMenu}" .....
This how you button should look like (more or less)
<h:commandButton value="doSomeThing">
<f:ajax render="#{components.mySelecOneMenu.clientId}"/>
</<h:commandButton>
add this to your faces-config.xml
<managed-bean>
<description>Holder of all component bindings.</description>
<managed-bean-name>components</managed-bean-name>
<managed-bean-class>java.util.HashMap</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
Here some detailed explanation of what I just recommend you to do
How do I break the tyranny of the clientID?
JSF component binding without bean property
if they are not in the same xhtml, do you include one in the other? If not, just change page and it will show the correct one.
But I don't think I correctly understand your question.
Add some code please
I find that component should be in same form an call ids start in form to component, its prefered put id every panelgrid, panel, etc because you have to call every component englobe comoponent that you want render.
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>
