I'm trying to create multiple dynaforms in my page which will repeat multiple times by clicking button.
To do this i've used ui-repeat but this is not displaying any dynaform at all.As an alternative solution i have used primefaces datalist(or datatable) they are able to repeat the dynaforms. But here in this solution i'm facing another problem with pe:timepicker, that is if i change value in one time picker that effect all the time pickers in repeated dynaforms.
Is there any solution for repeating dynaforms in ui-repeat. How to isolate the timepicker value change specific to dynaform.
I am using JSF2.1.24,primefaces 4.0-snapshot and primefaces-extention-1.0.0.RC1.
ui:repeat was always buggy. And yes, DynaForm works within PrimeFaces data iteration components. How do you change value in pe:timepicker? There are some tricks for DynaForm. See e.g. this one.
I would suggest you ask in our sub-forum for more information.
Please also use the last final releases 4.0.0 and 1.0.0 respectively.

I have a strange situation where one needs to dynamically populate dropdown values. The best idea I have come up with is creating a button, which triggers ajax request that fetches new dropdown values and on complete updates the dropdown and displays it.
I was wondering if there is any other more elegant way of handling situations like this. I am using the latest primefaces version 11.0.0.
I suggest to use the p:autoComplete component with the dropdown attribute set to true instead. It allows you to get the values when the button is clicked or when a query is typed. You don't need to take care of updating the component yourself. The only thing you need to do is have a completeMethod in your bean or have a completeEndpoint (REST endpoint).
With PrimeFaces 12 you can even (re)use a LazyDataModel as a suggestions provider.
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.
I'm looking for a ready made, freely available component that provides the following features:
editing list entries
deleting entries
adding a new entry - possibly invoked multiple times
bind to property in managed bean of type List, or similar
optional: reordering entries
optional, simple: allow verification that at least one element is entered (required="true"? required="1"?)
optional, better: restrict by minimum and maximum allowed number of elements
The simplest way to allow editing entries would be to represent them as input element. Preferably the element won't need to sync to the server for every change in the number of elements.
Alternatively: is there a trivial way to create or compose such a component oneself?
If this if of importance: currently I'm using Richfaces 3.3.3 and MyFaces 2.0.
Edit: The component is expected mostly to be used for creating new lists from scratch, so that should be as simple for the user as possible. Preferably just tabbing to the next empty input element automatically created at the end of the list. I'd like to use the component for editing these lists, too, but that feature is expected to be used much less often.
You could take a look at Primefaces p:collector. The example in the Primefaces showcase is a good starting point. It can be used for adding elements to a list and for editing and removing these elements.
Probably the simplest way that I would know of going about almost all of these is the PrimeFaces dataTable component. With the exception of adding and deleting entries inline, all of this comes out of box. Deleting entries can be as simple as adding a delete button in a row and adding entries can be done through invoking a modal dialog with a form to create a new entry, add it to the backing bean list for the table, then asynchronously updating the dataTable.
http://www.primefaces.org/showcase/ui/datatableHome.jsf
It really does seem to be the most fully featured JSF dataTable component out there.
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'm developing an application in JSF 2.0.
I was wondering if there is a JSF component that supports an autocomplete function and that can hold multiple values (that binds to an array or a list). I don't have the time and knowledge to create such a component myself.
I know PrimeFaces has got the p:autoComplete (http://www.primefaces.org/showcase-labs/ui/autoCompletePojo.jsf) component, but it can only 'hold' one value. I'd need a component that can do what p:auotoComplete does, but multiple times; the textarea should be able to display multiple values. Is there a library that contains such a component?
Any help would be greatly appreciated.
The latest PrimeFaces snapshot 3.1 got AutoComplete - Multiple Selection
You can get it from here
3.1-SNAPSHOT
You might see this Richfaces example. I think that tokens and autoFill = "false" will work.
