JSF 2.0 f:ajax: How to limit what is sent in AJAX request?

Is there a way in JSF 2.0 with f:ajax (or direct JavaScript equivalent) to limit what parts of a form are sent in AJAX request, like it's counterpart f:ajax render attribute which limits what is returned back from AJAX request.
When f:ajax execute attribute is set to some value it only affects what is processed on server, but whole form is still sent as part of AJAX request.

This is a bug. onerror was not getting set probably in AjaxBehavior component. Fix in progress.
Will let you know when fix is in.

N95 how to limit what directory the Music Player s...

Hi. I installed some sofware in E drive (memory card) with some sound files (an IM program). The Music Player managed to find them and added them to the library. But those files are really nudge sounds and not musics.
So I really prefer it not searching directories other than the one I set to search. I would like to set it to only search "Music" folder if I could.
Could you help me out? Thanks.

If you hook up via USB you can change the file attribute to "Hidden", they then don't show in Music Player. Refresh Music Player after changing them.
I haven't done it for a while so those instructions are a bit vague, if you search this site or some of the others you'll find more detail.
I had to do it after I installed "Step Counter" -- it's sounds showed up on Music player.

How to tell what type of sample is requested by MediaStreamSource.SampleRequested?

MediaStreamSource.SampleRequested handler gets MediaStreamSourceSampleRequestedEventArgs which has s StreamDescriptor.
The StreamDescriptor has property Name, but it does not seem to work. When the MediaStreamSource is created, both VideoStreamDescriptor and AudioStreamDescriptor have their Name property set, but Name is null in the SampleRequested handler.
Hong

I think check the object type (e.g. if (args.Request.StreamDescriptor is VideoStreamDescriptor)...) is a hack. This will not work if there are more than one streams of the same type (e.g. audio). I would still like to know the official
way of doing this. I am also curious about the usage of the Name property.

How to limit the max dialog no that one user can use at the same time?

Hi,
I meet one performance problem that one user can open 6 sessions in the GUI and he/she can run 6 reports at the same time witch could occupy 6 dialogs in the sap R/3 instance. It makes poor performance for other users.
Would you pls tell me how to limit the no. of sessions one user can create at the same time or how to limit the no. of dialogs one user can occupy at the same time?
Thanks a lot!
I used this parameters in the default profile as blew:
rdisp/rfc_check 1
rdisp/rfc_use_quotas 1
rdisp/rfc_max_own_used_wp 20 (means: 20%)
It still didn't work.
Sean

Hello,
We can reserve DIA W.P by giving value to the parameter :- rdisp/rfc_min_wait_dia_wp=1(default)
that have to necessarily remain free for other users.
This parameter is used to reserve a number of dialog work processes for Dailog mode.
For eg. If 10 dialog w.p. are configured for the instance(rdsip/wp_no_dia=10) and the parameter rdisp/rfc_min_wait_dia_wp=3 is set,parallel RFC's can occupy a maximum of 7 DIA W.P.3 DAI W.P. always remain free for dialog mode.
But now the question is how we assign/restrict this free dialog w.p. to the specific user.

How to limit the number of items in a KPI Status list web part?

How to limit the number of items in a KPI Status list web part? There is no paging option for Business Category Status list or any limit can be made by changing the Item limit in default view unlike other SharePoint List web parts. So How to achieve it?
Kindly help.

Hi,
According your post, I know you would like to set the item display limit in Status List web part.
In the web part, the number of items to display is based on the view which you selected when configuring the web part. The default view for status list is status list view.
However, I am not able to limit the items’ display number of the status list view. After changing the items limit, the list item displayed would not match the number specified by Item Limit. Thus, it is not possible to limit the number
of items in the Status list web part.
It could be a potential issue in SharePoint 2010.
We will log this issue to our suggestion box. As after the submission, we may not have any time guarantee when the fix may be released, but it may come out on next cumulative update.
Appreciate your time and efforts.
Thanks.

How to limit the number of items that a list control can hold?

Hi,
I am using a Flex3 List control for one of my projects.
I add drag & drop functionality to it, so that i can drag & drop elements from one control to another.
How to limit the number of items that a list control can hold / can be dropped in a list control ?
- Sen.

1. Listen for the dragdrop event on the control you are dragging onto.
2. check the length of the items in the dataprovider - if it exceeds your maximum override the default drop action with e.preventDefault(); (assuming you used e for the event on the handler).

How to limit the number of rows in a smart form , sap script.

Can anyone tell me how to limit the number of rows in the output of a sap script/smart form. I have tried "protect/endprotect" in sap script but have no idea of how to do in smart form. In sap script the only way it has happened is by reducing the size of the main window.

Hi,
In Smartform also, why dont you try reducing the size of the window if you want to limit the rows in it. Also if you are printing Line Items in a LOOP, you can write
LOOP AT T_ITAB FROM 1 TO N in the LOOP Node if you know how many records exactly you want to display in 1 Page processing.

Thank you very much for your helps.

Thanks Thomas, excellent suggestions as always.
If anybody wants more information regarding Thomas' suggestions please refer to
Oracle9i OLAP Developer's Guide to the OLAP DML for the AW Permit command.
In sumamry: To create permission programs, you define two programs with the names permit_read and permit_write. In these programs, you can specify PERMIT commands that grant or restrict access to individual workspace objects. In addition, you write these programs as user-defined functions that return a Boolean value, and the return value indicates to Oracle OLAP whether or not the user has the right to attach the workspace.
For relational security there is an excellent tutorial on the database pages of OTN, follow this link:
http://otn.oracle.com/obe/start/index.html
then follow the links for Oracle9i Database Release 9.2.0.2 - Security - Creating Label-based Access Control. This module describes how to use Oracle Label Security to setup security based on label policies
These security layers should be transparent to the OLAP metadata layer, therefore, once you have implemented your chosen security method your BI Beans application will only need to connect with the appropriate user to inherit the security layer.

How do I limit what movies are displayed at the top on the main screen

Is there any way to limit what movies are displayed at the top on the main screen when menu Computers are selected?
Currently it shows ALL of the content in the Movies folder in iTunes, but I would like to not show my 1 million 5-second videoclips and only the "real" movies.
Any suggestions?
Thanks in advance
Bjoern Dirchsen

I think you are right. It's the latest videos added that are displayed first. Makes sense.
I'm using a PC so it's a bit hard to work with iPhoto . However, your comment did give me a hint to how to solve the problem.
I moved all my video-clips out of my Movies folder and into my Pictures folder.
Then I changed Photo Sharing in Itunes to include Videos
And voila! The main screen now shows only my "real" movies. Sorted by latest added - but I guess that's the best we can do.
Thanks for a super-fast answer.

How to limit numbers of rows in a sortable table

I created a table that shows the first 25 of over 200.000 rows. This table is sortable. That means that I cant use the topN function to restrict the total numbers of rows.
Is there any chance mabe by using the advanced tab to limit the rows.

How to limit threads in a Java QuickSort algorithm.

With the following piece of code, I quickly run into OutOfMemory exceptions, since the code starts creating Threads exponentially. However, after waiting for a long time (for all the exception texts to print out, obviously making it slower than running it with one thread only), the program eventually ends with the correct result. Is there a way to run the code as is, but making sure that no more that x threads are running at a time?
things I have tried:
- sleeping the current thread - makes it slower than one-thread.
- looping blank while Thread.activeCount() > x - doesnt work at all
- suspending resuming threads based on the activeCount - doesnt work too
Code:
import java.util.*;
import java.io.*;
public class ThreadedSort extends Thread{
private ArrayList<Integer> _list;
     public ThreadedSort()
          _list = new ArrayList<Integer>();
     public ThreadedSort(ArrayList<Integer> List)
          _list = List;
     public void run()
          threadQuickSort();
public void threadQuickSort()
          try{
if (_list.size() < 2)
return;
Integer pivot = new Integer(_list.get(_list.size()-1));
          ArrayList<Integer> left = new ArrayList<Integer>();
          ArrayList<Integer> right = new ArrayList<Integer>();
//ListIterator iter = arr.listIterator();
          // *** optimize here
for (int i = 0; i < _list.size()-1; i++) {
               Integer next = (Integer)_list.get(i);
               if (next <= pivot)
                    left.add(next);
               else
                    right.add(next);
          ThreadedSort LeftThread = new ThreadedSort(left);
          ThreadedSort RightThread = new ThreadedSort(right);
//          System.out.println(Thread.currentThread().getName()+" --> "+Thread.activeCount());
//          Thread.sleep(4000);
          LeftThread.start();
          RightThread.start();
//          System.out.println(Thread.currentThread().getName()+" --> "+Thread.activeCount());
          LeftThread.join();
          RightThread.join();
          _list.clear();
          list.addAll(LeftThread.list);
          _list.add(pivot);
          list.addAll(RightThread.list);
          }catch (InterruptedException ie) { ie.printStackTrace(); }
          return;
public static void main(String[] args) { ///////////////////////////////////////////
          Random rand = new Random();
          ArrayList arr1 = new ArrayList();
          long before_threadedQuickSort, after_threadedQuickSort;
          try{
          FileWriter fout = new FileWriter("out.txt");
          BufferedWriter bw = new BufferedWriter(fout);
          before_populate = System.currentTimeMillis();
          for (int i = 0; i< 2000; i++){//***
               arr1.add(rand.nextInt(2000000));
          after_populate = System.currentTimeMillis();
          ThreadedSort sorter3 = new ThreadedSort(new ArrayList(arr1));
          before_threadedQuickSort = System.currentTimeMillis();
          sorter3.start();
          sorter3.join();
          after_threadedQuickSort = System.currentTimeMillis();
          bw.write("time for threadedQuickSort: " + (after_threadedQuickSort - before_threadedQuickSort)); bw.newLine();
          bw.newLine();
          arr1.clear();
          bw.close();
          }catch (Exception IOException){};
          System.out.printf("\n\n");
} //end of main
} //end of class

So you dont have to go thru the code:
Quicksort:
with one thread only I start the sorting by choosing a pivot from the initial list and then generating a left list (all values less then pivot) and a right list (all values greater then pivot).
then i recursively call quicksort with the left and right lists.
with one thread that works fine.
threadedQuickSort:
each thread object has a variable _list that keeps its list.
from the initial thread, i do generate again two lists (left and right) but then i construct two threadable objects with those lists and start them, creating for each list a new thread.
so each thread will create two new threads.
for a initial list with up to 2000 rows, that yields to the correct result although much slower than the one-threaded version. maximum number of threads ever used was around 500~600.
for a list with 20000 rows, my machine chokes at around 2600 threads. (OutOfMemory exception)
My Processor is a 8 core (each core can run up to two threads) giving me a total of 16 actual threads i can work with.
So the question is how to limit the threads that are created to 16. There is no method in the Thread class where you can specify the max number of threads in a threadgroup.
@ jverd:
I looked at ThreadPoolExecutor, but it looks kinda complicated. I see that the idea is creating a queue of jobs to be executed (which would be the different sublists (left and right lists), and then using the specified number of threads to work with the queued jobs, but im failing to understand how it works. Can you point to a simple example somewhere showing how to declare a ThreadPoolExecutor object and work with it. thanks

How to limit the number of boxes to tick in LC

I would like to know the "javascript" in Lice Cycle to limit the number of boxes ticked
for example i have 20 boxes and i would like that the client can only tick 5 boxes
thank you

Thank you Steeve
But my problem is that i don't know which boxes the client will want to tick so all boxes have to be available at the beginning.
When the client will have ticked 5 boxes in this case and only in this case, all others boxes must become unavailable so it is very difficult to set up
if you have any idea
thanks anyway

Subject: How to limit the number of boxes to tick in LC
This is a form validation issue. For example, you may have a text field and the value entered into that field determines which checkboxes must be completed to satisfy a validation or business rule. The attached sample requests the value "foobar" to be entered into a text field. If you enter "foobar" and exit the field, 2 of 3 checkboxes have the access property changed to "protected", meaning a user cannot no longer select those checkboxes.
// form1.page1.subform1.input::exit - (JavaScript, client)
if (this.rawValue == "foobar") {
form1.page1.subform1.cb2.access = "protected";
form1.page1.subform1.cb3.access = "protected";
