I have DIV element with a header style enclosing a h:outputText but when the page renders i see the HTML is formed in such a way that my div doesnot contain the label generated by the h:outputText instead i see the label above my DIV . Am i doing it wrong? i tried f:verbatim but didn't help either
Based on your question history you're using the ancient JSF 1.1. The <f:verbatim> way should work. Perhaps you've enclosed JSF components inside <f:verbatim>. You should not do that. It should only contain raw HTML.
<f:verbatim><div></f:verbatim>
<h:outputText value="Some text." />
<f:verbatim></div></f:verbatim>
Since JSF 1.2 the <f:verbatim> is not necessary anymore. JSF 1.2 should work on all environments where JSF 1.1 is been used. I strongly recommend to upgrade.

I want to use the rendered attribute in a ui:fragment to conditionally render a span element in my JSF 2.2 facelet. The JSF 2.2 documentation of ui:fragment lists rendered as an allowed attribute. I am using MyFaces 2.2.12 as JSF implementation, however, and the MyFaces 2.2 documentation of ui:fragment does not list rendered as a valid attribute.
I tried using rendered anyway, and it worked. However, my IDE - IntelliJ - rightly highlights the rendered attribute as an error and tells me it is not allowed in the ui:fragment element.
I saw a response in ui:fragment rendered attribute not working after upgrading Facelets to JSF 2 that there was a documentation bug where rendered falsly wasn't listed in the JSF 2.0 documentation, but the response says nothing about JSF 2.2 or MyFaces 2.2 (presumably because it dates before the release of JSF 2.2).
Is the missing rendered attribute in the MyFaces documentation also just a bug?
With multiple such occurances of the ui:fragment element in a single Facelets file, these "false" errors make finding real errors quite cumbersome. What is the recommended solution for this problem, if it really is just a bug in the documentation?
rendered is valid attribute in ui:fragment and ui:component in JSF 2.0, 2.1, 2.2. See JSF 2.2 View Declaration Language.
Some IDEs do not propose this attribute in autocomplete (content assistant) mode and validate it as "Unknown attribute". This happens because the rendered attribute was missing in the tag file declaration in JSF 2.0 (even if attribute was presented in the UIComponent) and the IDE validation is based on the tag file declarations. Issue was fixed in JSF 2.1: the missing attribute was added into the tag file declaration. Validation in IDE not always reflect to this change.
I need to complete a xhtml page with some JSF code (with p:panel and p:datatables, etc.) from a managed bean, but I'm not sure that is possible.
My attemps:
1º
<h:outputText escape="true" value="#{controller.jsfString}"/>
It's not be able to understand "p:" components, only simple html.
2º
<ui:include src="#{controller.jsfString}">
It expects a xhtml path, not a String.
I don't know what else try... Is it even possible?
It's not be able to understand "p:" components, only simple html.
Of course it is not!
The h:outputText value is evaluated at view render time, so if you render JSF tags, they won't be evaluated again since rendering is done.
In principle, it could have been possible to add JSF tags this way using the JSTL <c:out>, but it is not available in JSF facelets.
Anyway, just tell yourself that it prevents you from making bad design.
We'll need more information regarding what the controller is supposed to output in order to help you.
Here p means prime-faces u need to include prime-faces dependency in pom and enable tag lib for prime-faces in XHTML then u can use the all the prime-faces components.
Is there a JSF 2.1 component which lets me conditionally render (or not render) all its content? Something like
<h:component rendered="#{user.loggedIn}">
...a bunch of jsf components and HTML code...
...even more HTML code...
</h:component>
I am using PrimeFaces 3M4 as this may influence your answer!
<h:panelGroup>
If you set attribute layout="block", you will have a <div> tag
Otherwise, you have a <span> tag.
In general most of jsf components support the render attribute (never bumped in some that does not),
container components like h:panelGrid or h:panelGroup supports the rendered attribute and if its set to false all its child will be hidden too
Same goes for the primefaces components ,and if not it probably a bug (i think there was an issue with tabview of primefaces)
Here's a link for primefaces user guide, you can find supported attributes of all primefaces components there User’s Guide for 3.0.M4
When the Apache My Faces JSF 1.2 Implementation renders an HTML page behind the scenes , is it even possible to set/code something which will display a pure HTML Table / DIV (NOT the jsf component ) conditionally. When I searched , I saw that , using h:panelGroup is a solution, but I haven't tried yet, posting here for any better methods or approaches.
Its almost like wanting to say - writing a javascript code in java and inject it when the HTML is rendered - is it possible?
Thanks,
Several ways.
Use <h:panelGroup layout="block">. It renders a HTML <div> element.
<h:panelGroup layout="block" rendered="#{bean.condition}">
content
</h:panelGroup>
Wrap the HTML <div> element inside a <h:panelGroup>. Without any client-side attributes like id, styleClass, onclick, etc, the <h:panelGroup> won't render anything. With them it would however render a <span> element (or <div> if layout is set to block).
<h:panelGroup rendered="#{bean.condition}">
<div>content</div>
</h:panelGroup>
Wrap the HTML <div> element inside a <f:verbatim>.
<f:verbatim rendered="#{bean.condition}">
<div>content</div>
</f:verbatim>
It's by the way not so special that MyFaces generates HTML. The Mojarra JSF implementation also does that. The competitors Struts2, Spring MVC, Wicket, Tapestry, etc..etc.. also. Microsoft ASP.NET MVC also. PHP also. All server side languages in fact. Simply because of the fact that the webbrowser doesn't understand them. It only understands HTML/CSS/JS ;)
As to mixing JavaScript with Java/JSP/JSF, you may find this article useful.
Eg: h:inputText will render a "input type='text'".
What jsf tag can render a "div" tag?
You can create a DIV component using the <h:panelGroup/>.
By default, the <h:panelGroup/> will generate a SPAN in the HTML code.
However, if you specify layout="block", then the component will be a DIV in the generated HTML code.
<h:panelGroup layout="block"/>
In JSF 2.2 it's possible to use passthrough elements:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:jsf="http://xmlns.jcp.org/jsf">
...
<div jsf:id="id1" />
...
</html>
The requirement is to have at least one attribute in the element using jsf namespace.
Apart from the <h:panelGroup> component (which comes as a bit of a surprise to me), you could use a <f:verbatim> tag with the escape parameter set to false to generate any mark-up you want. For example:
<f:verbatim escape="true">
<div id="blah"></div>
</f:verbatim>
Bear in mind it's a little less elegant than the panelGroup solution, as you have to generate this for both the start and end tags if you want to wrap any of your JSF code with the div tag.
Alternatively, all the major UI Frameworks have a div component tag, or you could write your own.
you can use myfaces tomahawk component
http://myfaces.apache.org/tomahawk-project/tomahawk12/tagdoc/t_div.html
I think we can you use verbatim tag, as in this tag we use any of the HTML tags
