I'm interested is it possible to create tabs with Primefaces using this example?
The idea is to create dynamically loaded tabs and when I switch between pages to display "Loading" at the top right of the page. What are the usual ways is this case?
The example you reference in your question carries the answer to the question. Generally, you have two options
Primefaces ajaxStatus component is designed specifically for your use case and is also the same component used in the dynamic tab sample you linked (albeit the PF team neglected to reference/declare it in the sample markup for that example). It's the same component that is used to generate the "loading" pinwheel you see in that example
A more powerful/exotic option is the blockUi component that will achieve the same effect, albeit with a little more in terms of options and visual effect.

I am currently trying to create a p:menubar which has one dynamically created submenu, but all the other submenus should be normally declared in the xhtml. Sadly I couldn't find any information on how to do so, as it seems that you always have to create a MenuModel and use that as the model for a complete p:menubar.
When just using two separate menubars it is possible to have multiple submenus open at the same time, which leads to them overlapping. And also the spacing is wrong then.
EDIT: I can't use JSTL, so the solution with c:forEach is not possible.
It has to be dynamic because the items are loaded from the database on each request.
EDIT 2: I could use JSTL, but I still don't really grasp how this could best be accomplished. I wan't to have a menubar with some submenus being normal static ones, but one submenu is built dynamically in the code (for every request, nothing with ajax). This dynamic submenu however has multiple child submenus which have their own children in turn, so in theory I would have to somehow iterate recursively over all children.
I am using Primefaces 8.0 and JSF 2.2
Thank you Kukeltje for answering my questions, I now ended up using c:forEach like in the linked post.
Ok, I have been trying to find answer for two days now. I created new Web Application and added JSF framework to it. But when I opened a palette I can see only few tags to be dragged and dropped. I can see HTML, HTML Forms and JSF categories with only about five tags in each. Do I have to add some library or something? Thank you for help.
You better get rid of Netbeans JSF palette when adding components to your page. Writing directly on the page you will be more productive because you have code completion assistance. If you look at the JSF palette it is like a set of squeleton generators more than an exhaustive components set. So basically I would use, perhaps, only the JSF Data Table [From Entity] palette item.
I want the below look and feel functionality in jsf?
http://livedemo.exadel.com/richfaces-demo/richfaces/componentControl.jsf#
If you go to the above url code,
When you click on View Source link , how it shows?
and in the same way, when you click on hide link, it hides the code.
I want that same look and feel in my project...
How is it be done? How to achieve it in jsf?
If you are using RichFaces, you can use the <rich:effect> tag component which uses Scriptaculous. This is a js framework who enables to add effects in pages. In the example above, the effects used are Effect.SlideDown and Effect.SlideUp (sorry for not placing the link here, but as a new user I can just post a max of two hyperlinks). If you are not using RichFaces, you can still add the js libraries to your web project and use them to add these great effects.
I have a form which one of it's fields is a code and description, also a button for opening a popup window that contains a list of all of the available codes.
when the user double clickes a row from that table i want to set these values to the code and description. - how can this be done?
Another question, I want to create this popup and table to be initialized dynamically - by that i mean that if i have a few forms in my application, when ever i have a field which has a description i want to be able to open this popup and to see the available list for that field. (every field can be from a diffrent table). is it possible to create something like that? if so, how?
Any help will be appritiated,
Thank's In Advance.
Yes, it is possible. Even more, many component libraries have ready to use popup/dialog components, such as RichFaces with <rich:popupPanel> and PrimeFaces with <p:dialog>.
If you do not want to use a component library for some reason, you would need to create a custom component for this which generates basically an absolutely positioned HTML <div> element with a CSS overlay which get shown/hidden by JS on a particular click/action. The HTML/CSS/JS part should be relatively simple if you are familiar with those languages. The JSF part is somewhat hard if you have never created a custom component before, but it should be possible with a composite component as well, so you could also just create one with pure XHTML. The updating/refreshing can just take place by the usual <f:ajax> means.
I have links and pictures related to these links on my page. I want to change the pictures everytime when onmouseover event occurred in the links. I want to do this in JSF.
A lot of Thanks to everyone.
You are looking specifically for JSF to do it, or you are open to other Javascript frameworks that provide a slick and easy solution on this? For example Jquery and Dojo etc may be easy to incorporate in your application and will give Rich UI effects.
On the other hand if you are looking at JSF specifically for these UI effects than probably I can try to think of some ways and let you know.
JSF isn't designed directly to do this; It's designed to give you the tools to do this yourself. In order to do this you would need to create a custom JSF component to do this and you would use Java script to do it.
You could possibly find a JSF framework that does this already (a4j, IceFaces, etc.) but this is such a simple and well documented JavaScript thing that just tossing a little Java script among your JSF is perfectly acceptable. However, if you don't want to reinvent the wheel, take a look at those other options.
Javascript solution:
Define onmouseover event on the commandLink tag calling some kind of javascript you may give link address from like onmouseover="doSomething('addressOfImage')" then in doSomething javascript method, first find the image, then set src attribute of a default image to given address.
JSF Solution:
You might want to use a4j for this.
Add a4j:support to link for onmouseover event then just rerender graphicImage component ofcourse you need to give value of graphicImage dynamically. There is an example of using a4j support below. You can add this a4j:support between your link tags for mouseonover event. Then manage everything on backing bean to handle which image to be displayed.
example
<h:graphicImage id="imageToBeRendered" value="#{myBean.imageAddress}"/>
Just google a4j if you have no idea.
