I have one searched arraylist that i am getting from Database for that array list i want to apply paginataion with links First, Prev, Next, Last and Goto page dropdown here i don't want to call database for every request(i.e First,Prev,etc) i want to use arrylist that returned at the time of search.And one more requirement is field level sorting need to do Ascending,descending if user clicks on header field.can any one help me to fix this i want to use only JSF2 no RichFaces,etc
Thank in advance.
Why do you not want to use rich or prime faces or others? Just use primefaces datatable with paginator="true".
If you don't want it, but want to do it the hard way. I suggest you fetch everything from database. Use a datatable and in the getter of that table, you only give back a portion of your array. (index 10 to 20, or index 20 to 40 or...)
On top or bottom of your datatable you put some outputlinks. These can set the indexes you want to retrieve.
Hope my explanation is clear.
In case Myfaces Tomahawk is an option for you...
I see it (Myfaces Tomahawk) as a bit different from PrimeFaces/Richfaces cause MyFaces are responsible for the MyFaces JSF Implementation as well (so it could be an excuse for using Myfaces Tomahawk), so you can use the Myfaces JSF implementation + Myfaces Tomahawk
Take a look at the Myfaces Tomahawk datascroller

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 am trying to get the reusable group of jsf 1.2 components inside a panelgrid using Facelet tag file. #Balusc's previous answer at How to make a grid of JSF composite component? was a fabulous resource. I have a couple of followup questions:
In my c:when how do I test for the tagName itself instead of checking for the attributes. Instead of
<c:when test="#{type != 'submit'}">
I want to check tagName itself to decide how to format it. If 'input' do xxx.
2 Is this approach is still valid with jsf 1.2 other than f:ajax? If yes, can I replace with a4j:support...?

I'm not sure how this question makes sense. It sounds like that you're approaching something not entirely right. Do you maybe have copypasted exactly the same piece of code over multiple tag files? You should not do that. Make it a reuseable <ui:composition> or maybe <ui:decoration> instead which you compose/decorate in every tag file along with a fixed and unique <ui:param> value depending on the taglib file.

Being able to create tag files is not necessarily specific to JSF, but to the view technology used, which is in this case Facelets. You can even do similar stuff in its predecesor JSP, see also this answer for an example: JSF 1.2 custom component from jsp:include It should work just fine in every JSF version supporting the view technology in question.
As to ajax support, it doesn't matter to the tag file what you're all doing inside the tag file. If you want and can use <a4j:support> then just do it.
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.
I am trying to make a search page using JSF, EJB, JPA & Primefaces with Pagination from an Oracle database table.
The page has two regions (1) region for entering search parameters
(2) region with a datatable showing the search result. This datatable supports pagination.
I have used standard code generated using Netbeans IDE, but dont know how to pass the parameters while clicking the search button and show the results based on the search in the datatable.
Please help me with sample code.
Thanks in advance.
For the input, just use a normal form like as you've created in a hello world tutorial. For presentation and pagination of the results, use PrimeFaces LazyDataModel. See also their showcase example.
Can we sort values in column of a panelGrid. If yes, can I see an example
Rather use h:dataTable to represent a dynamic table which is backed by a List<RowObject>, wherein RowObject is basically just a Javabean (DTO - Data Transfer Obejct, VO - Value Object, whatever you call it :) ) representing a single row.
Such a List can be sorted using Collections#sort(). All you need to do is to implement a Comparator which takes care about the ordering. Then in the JSF page just have a bunch of buttons or links which calls Collections#sort() on the List. Those buttons/links just have to pass the sortfield along.
You can find here a basic example: http://balusc.blogspot.com/2006/06/using-datatables.html#SortingDatatable
No, you can't. <h:panelGrid> = <table>
If you want sorting, look at Richfaces or another component framework (Icefaces, primefaces, trinidad, tomahawk, etc). There are <x:dataTable> components there which allow sorting on their <x:colum>.
