2 VO with same entity, without  pool problem

I have 2 ViewObjects with sabe entity (ChairmanView, AllEmployeesView). Structure of entity (Id, Code, Name, Surname....)
VOs are in same Application module.
VOs are linked by a ViewLink 1 to 1 (ChairmanView.Id to AllEmployeesView.Id)
When i create a new Chairman, automaticaly apair in AllEmployeess and work fine, but when i remove de AMPooling (-Djbo.ampool.doampooling=true) it create perfect but when i modify the name appears this error. (JBO-33035: Row currency has changed. The expected row key was null.)
What can I do?
Thank you for all

Yes, you can use them on up to five devices. You can also download apps you lost or deleted again for free: http://support.apple.com/kb/HT2519

    My wife and I both have the iPhone 4 and it's actually pretty simple. Add another user on your MBA (her) and she can use the other iTunes when she is logged in. The iTunes is empty and will erase her iPhone, so be sure that she syncs her iPhone, then back up her library onto a portable media device like I did (SD Card) and reload it onto her empty iTunes on your MBA before she attempts to sync with it.
    Works well...

  • I'm connected to the wifi at home but no internet access. i was surfing on the same wifi without any problems. and also this issue is for other wifi network.

    hello everyone.
    i was surfing browsing and downloading on my iphone 4 on my home wifi and other places without any problem but today i found out that even though i'm connected to my wifi i got no internet access. i also got this new problem, my led flash is on.  if i tilt the device the flas dims a bit. i tried switching off the device but still the flash is on. i tried using at other wifi network same problem. i tried forget this network, switching off and turning on the device i also tried reseting the network and also hard reseting the device. but still same problem. what can i do about this? and if i send it to apple what are my options? i got warrant coverage so will they be able to repair it ? if they are not able to repair then will they give me new iphone 4 or refurbished iphone 4 for replacement?

    Apple does not repair devices.  If they are covered under warranty, the device is replaced.  You will not get a new phone, you will get a service unit which is as good as if not better than new.
    If all the basic troubleshooting from the User's Guide has been done and the device does not get Internet access via Wi-Fi from multiple locations, the only thing left is to take it to Apple.

  • I bought a new iMac this week but am struggling with the WiFi as it intermittently drops.  I have an HP notebook in the same room without any problems. It keeps on "looking for networks" it then connects and drops and starts again.

    I am connected to the internet but it keeps on dropping all the time, same with my email accounts.  Other hardware is running well without any issues.  I have gone through the Wi_Fi faultfinding tree but still the same.  I have also spoken to a Apple sales consultant in the store that suggested the software be reloaded which could be the case but I doubt.  Any ideas?????

    This may be a long shot or may not apply but check out this article: Remove Bluetooth PAN Helps Resolve Wi-Fi Conflict in OS X Yosemite?

  • 2 users with same User ID, Big Problems

    I currently have User A from macbook 1 (old user I no longer use) and User B from macbook 2 and 3 (new user I've been using for ~4 years).
    I had upgraded from macbook 1 to 2 to 3 and am currently running 10.9.5
    I thought I had deleted User A through Finder a couple months ago. Since then I've been having mild annoying issues
    - ppt crashes in slideshow
    - quicktime player won't open
    - installer doesn't work most of the time
    - sometimes, my current user B will randomly switch to user A while my computer is on
    - Some applications will randomly complain they can't open because they can't find User A's directory.
    I ran dscacheutil -q user | grep -A 3 -B 2 -e uid:\ 5'[0-9][0-9]' and found
    name: A
    password: ************
    uid: 501
    gid: 20
    dir: /Users/A
    shell: /bin/bash
    name: B
    password: ************
    uid: 501
    gid: 20
    dir: /Users/B
    Running the command . -list /groups GroupMembership | grep user
    returns nothing for user A and returns the following for user B:
    _appserveradm            B
    _appserverusr              B
    _lpadmin                       B
    admin                          root B
    com.apple.sharepoint.group.1   B
    I'm at my wit's end here. I tried using console to debug the reason behind why certain applications crash and the common theme seems to be "com.apple.launchd.peruser.501: (......................................) Could not setup Mach task special port 8: (os/kern) invalid argument"

    Hi Drew and Linc
    Drew, I see what you were going for, but I only wanted 1 user. I tried doing both your methods and am unfortunately still having the same issue.
    I found a old working backup on an computer of mine and am comparing the users on that computer and this one. After running dscacheutil -q user | grep -A 3 -B 2 -e uid:\ 5'[0-9][0-9]'
    my current computer shows:
    … (not relevant info)
    I could move the working backup to my current computer, but It's over a year old (lots of new info on my current computer, it would be a huge pain to manually move everything over.
    Does the appearance of macports and messagebus users in my current glitchy computer an issue? Why don't these users show up in my old functional computer?
    Thanks for your help.
    You tried both methods? So when you tried my method of erasing & reinstalling the OS it failed did it? You then restored this old broken OS back to the Mac? Be honest – you didn't erase & reinstall did you?
    Stop messing around in Terminal, backup, erase, reinstall, migrate the users you need by hand. It is incredibly simple if you stop getting distracted by Terminal.
    I don't see why you have to bring another computer with an old backup that you do not want to use into this issue! Stop 'thinking around' the issue at hand.
    Linc's method should have resolved this unless the OS was in a complete mess (which seems likely considering your desire to fool around in Terminal).
    The Macports user is from the software you installed, message bus is also likely to be from something else you installed (possibly via macports). Neither should effect the logged in user.
    It's looking like you are intent on playing with the OS (or more specifically playing in Terminal until things work), I can't bear to watch.
    Backup, erase the internal disk & move the users home folders to /Users in Finder (NO TERMINAL NEEDED) & re-add that user in Users & groups.
    If you need help with that I will explain (again), but you can continue messing in Terminal with things you already broke & don't understand in your own time.

  • Can I download music from my PC onto my new iPhone and still have my iPhone use iTunes on my Mac without a problem? I have no music on the Mac because it is new. Can I download music onto iPhone on both PC and Mac?

    Can I download music from my PC onto my new iPhone and still have my iPhone sync with my Mac without a problem?
    I've had an iPod over a year and have not done much with it except download music onto it from my PC. Just recently have purchased the iPhone.  When I got my iPod I didn't have a Mac, but now I do.  I am really into my iPhone, so now I want to make sure that I don't do anything wrong. So can I connect my iPhone to both my PC and my Mac without it getting mixed signals and stop working.  I have no music on my Mac but plan to download music into iTunes on it.  So can I download music from both computers without problems onto my iPhone?

    StoneMountainGirl,
    No. You can only music to your iPhone from one computer at a time.  If you try to load music onto it from a 2nd computer, it will erase the current content on the iPhone and replace it with whats in the iTunes library you are connected to,

    return (valid);
         } //end of method

    What you should be doing is returning false immediately if the input string is not eight characters in length and all digits. (Both are prerequisites for the proper functioning of your app.)
    A couple more suggestions won't hurt:
    (1) A method should do one thing and do it well. Your method is doing two things: taking input from a user and checking to see if a string represents a valid date. You can never use this method in situations where you'd like to validate a string as a date and not take input from a user. It cuts down on the usefulness of your method. Get that input stuff out of there and have the method just validate a string as a date.
    (2) The name of the method should immediately suggest what it does. Ditch that Enterdate name and call it isValidDate. Make sure you follow the Java coding standards and start the name with a lower case letter.
    (3) That switch statement sure is big and ugly. Why not just have an array of integer values, one per month?
    (4) I'd suggest another method, isLeapYear, that will take an int and return true if the number represents a leap year, false if not. You might find it handy to call elsewhere.
    It's called decomposition. Learn how to do it.
    This must be a school assignment. You're required to do this a certain way.
    I think I can write this method in many fewer lines. I'd do it like this:
    public boolean isValidDate(final String dateStr)
        try
            java.text.DateFormat formatter = new java.text.SimpleDateFormat("ddmmyyyy");
            java.util.Date dateValue = formatter.parse(dateStr);
            return true;
        catch (java.text.ParseException e)
            return false;
    }MOD

  • FF 3.6 AND 5 on same Mac, 1 profile - can I uninstall 5 without causing problems running 3.6 or with the profile?

    I upgraded from 3.6.16 to 5, but don't like how 5 handles tabs (auto reloading 'problem loading' tabs when internet connection is reestablished). So I installed 3.6 in a separate folder, e.g. both versions are on this computer. I went back to using 3.6, and let it upgrade to either 3.6.18 or 19 (don't recall which & it's not open right now). I'm having problems with it using too much CPU & Memory, and not sure if that's a difference between 3.6.16 & 3.6.18/19, or if having 5 on the same computer even if closed could be causing the problem.
    Can I uninstall 5 without causing problems with the 3.6 version and the single profile?

    If you haven't tried this, give it a try. It worked for me, hopefully it will work for you. In your version 3 firefox, disable all extensions, I had two plugins (doubletwist and joost, disable those if you have them). Then install firefox 5 by overwriting your version 3 firefox. It should work fine after that. I tried everything before, I gave that a last ditch shot. Oh yeah, before you install firefox 5, clear your cache of everything just to be sure.
    Hopefully that helps.

  • HT1414 Why do I get 'This message has no content' with some e-mails on my iPad when the same messages can be received on my MacBook Pro without any problem, and how can I fix it?

    Why do I get - 'This message has no content' - with some e-mails on my iPad when the same messages can be received on my Mac Book Pro without any problem and how can I fix it?

    Is this a POP (POP3) email account?  If so, you MacBook Pro may be retrieving the email and deleting it off the server before your phone can.  Another possibility is that both your Mac and your phone are trying to retrieving it at the same time, and the POP server, which will only allow a single email client connection at a time, is locking out your phone resulting in the "has not been downloaded from the server" error.

  • Sharing same entity object with multiple viewobject problem.

    Dear All,
    I have a common entity entity object, that i am using in 4 different vo(only the where clause is different),
    I have created 4 af:table from corrosponding vos, when i am inserting some records in any of the vo then all the vo is showing the same records.. even through each vo is having separate where clause,
    But when i do this with separate eo for each vo then it works fine..
    Here i just want to do with the single eo being shared by different vo of same kind.. except where clause, Also i want to know why this issue is comming on insert? is it normal expected behaviour ? If yes then how to overcome this problem..? Pls provide any good suggestions if you have..
    Thanks & Regards.

    Hi Sacha,
    Thanks.. i read it and found following
    You can globally disable this feature by setting the jbo.viewlink.consistent to the value false in your configuration. Conversely, you could globally enable this >feature by setting jbo.viewlink.consistent to the value true, but Oracle does not recommend doing this. Doing so would force view link consistency to be set >on for view objects with secondary entity usages that are not marked as a reference which presently do not support the view link consistency feature well.Now i am thinking to set it false.. but as doc says but Oracle does not recommend doing this. Doing so would force view link consistency to be set on for view objects with secondary entity usages that are not marked as a reference which presently do not support the view link consistency feature well,
    With what option should i go...?
    go with separate eo and vo..?

    I'm having similar issues.  The iPhone4's face time works just as it always did but the iPad4 is not working.  I can place a call but it won't connect, others can call and it rings but never connects.  I've signed in and out of iTunes, removed and reinstalled the wifi, hard restart, and anything I can think of.  It's driving me nuts!

  • Problems accessing tables in oracle database with ejb entity bean

    I have created a simple server application that uses an entity bean (version 2.0) for an existing table in oracle database, and a session bean that is used as an outside interface for performing operations on that table.
    after deploying the server and client application the client attempts to perform an operation with the session bean remote interface it obtained.
    The session bean uses a locale interface to communicate with the entity bean, but when it tries to use its methods (create, findByXXX) it always get the following Exception: java.sql.SQLException: ORA-00942: table or view does not exist.
    the table of course exists, and the username password I'm using has all the permissions needed for this table.
    note - I'm using the Forte enterprise edition 4.0 as developer tool.
    I'll be glad to get some help.
    Here is the full stack trace of the exception:

    Well it seems like the problems has a simple explanation. The Forte assigns a default table name (<entityName>EJBTable) when creating an entity bean from an existsing table in DB (which is not the same as the one it was created from !!!). Also, for reason unknown, when you deploy these entity beans, it doesn't even create the new table under its new name (even if instructed to).
    So using the Forte we managed to use successfuly only entity beans that were created "from scretch" (when deployed their tables are created).
    Does anyone know how to change the default name the Forte uses, and make it work properly with entity beans created from an existsing table (without going over the xml's) ?

    Welcome to the Apple Community.
    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.
