Delay-updates-until-end-of-tx flag behavior in WLS 6.1 SP4
Hi All!
I'm a bit in trouble with a strange behavior with the
<delay-updates-until-end-of-tx> tag.
I didn't find any message about my problem here around, so I don't
know if I missunderstand something. Has somebody had the same
(following) experience?
We are migrating from WLS 5.1 to WLS 6.1
We tried do keep ejbs "as are" in 5.1, so we're talking about EJB 1.1
on WLS 6.1: it should be allowed!
Everything works fine, but when a session bean (SL) modifies some
entity bean(CMP or BMP) and try to read from it in the same
transaction, read data are NOT up to date.
To solve this problem with WLS 5.1 we used the
delayUpdatesUntilEndOfTx tag, and it went fine, but with WLS 6.1 it
doesn't work, even if reading bea docs I understand it should.
Looking at the console, flags are correctly un-setted for the entity
beans we need, but the behavior is like if it wasn't.
Any idea?
Thanx in advance, Paolo.
Hi
Well, delay-updates-until-end-of-tx is setted tu false, so it
shouldn't wait 'til the end, but write immediately.
When I "read" I call finders.
Anyhow, I went on with tests, and tried to use EJB 2.0 entity beans,
and it works fine.
So now I have 1.1 session bean on 2.0 entity beans well working.
It seems that troubles are only with 1.1 entity beans on WLS 6.1.
1.1 entities on WLS 5.1, and 2.0 entities on WLS 6.1 are ok for me.
Maybe a bug?
Paolo.

Did u set delay-updates-until-end-of-tx to true or false?
When you do a "read", are you calling get cmp fields on the same bean instancesor
are you invoking finder methods?

Delay program until end TranslateTransition JavaFX
Hey everyone,
My name is Thomas and I am currently working on a final High School programming project. For this project we are programming a game with JavaFX, in which we feature several mini-games to improve children's mathematical skills. One of about 10 mini-games is a puzzle where you have to reach the exit of the level by sliding over ice.
Let me explain the mechanics of this mini-game. When you press an arrow the character has to keep sliding in that direction until it bumps into an object (I have four rocks & borders of the map). What I decided to do is make a function for each direction in which I define a translation of a certain distance, and then keep repeating this translation until there is an object right next to the character, at which time it will stop moving. In many programming languages this would be an easy task, but there is a problem in JavaFX: when I execute the translation the code will continue executing, allowing the user to press a button while still moving which should not be allowed: the code has to wait until the movement is complete. Most languages have a delay(x ms) function for this, but JavaFX does not have one.
I was wondering whether anyone knows a solution for this problem. I need to make a delay either in the TranslateTransition, or in a function since I made a while loop that keeps executing the translation but without a delay it executes the transition a million times.
Any help will be greatly appreciated!

New email on iphone 6 IOS 8 is delayed and won't update until you lauch the email app
New email that is received on an iphone 6 (IOS 8) doesn't update # until you actually launch the email app. At that time the new email badge updates and VIP notifications are activated. How do I correct this so that it updates immediately as email is received.
Hi Georgiegog,
If you are not getting updates in Mail until you launch the app, you may want to check in Settings to make sure that Push delivery is active, as noted on this page:
Mail settings - iPhone
Regards,
- Brenden -
Is there a way (or a setting) for my individual folders in Mail to automatically update across all devices? For example, if I transfer an email to a folder for follow-up on my PC - say 10th of the following month - the same folder in Mail on my iPhone doesn't update until I actually go into the folder and update manually. Interestingly though, if I create a new folder on any of my devices they automatically appear on the other devices so it is just the actual contents that I am referring to here. Appreciate any help or guidance.
Regards
JustinYou can turn mail off in the settings but then you can't use it for anything, including the "test" that you want to perform.
Settings>Mail, Contacts, Calendars>Account Name>Mail>Off. That totally turns off the mail account.
As long as mail is turned on and you launch the app, it will look for an download new mail. -
When ever iTunes updates, it ends up coming up with error message, iTunes did not install properly, please re-install iTunes, this is about the fourth time this has happened, end up having to take it to computer tech at a cost of $180, please help
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

URGENT SRM 5.0 ! Updating PO item BBP_PDPSET-IR_IND (flag Invoice expected)

This program must allow from PO number (header information) to update the field BBP_PDS_PO_ITEM_D-IR_IND (BBP_PDPSET-IR_IND) that is at item level.
Looking for FM for this update.

Lync Status Not Updating Until Group is Expanded
Hello all,
I am having an issue that I can't seem to figure out. For the Groups view, the group doesn't seem to update a person's status when collapsed. After it is expanded, is only then the status will update and the person will go into a different group or move
up or down the list, depending on filtering. Also if the expanded group extends past the bottom of the Lync window, those contacts don't update until seen. This also happens with the Status View as well. You need to scroll through the entire list to update
everyone's status.
Is this part of Lync or a bug? I am really hoping it is an issue because trying to find people after their status updates is annoying.Hi,
Did you try deleting the Lync Profile.
Please try to delete the profile and check the presence.
%UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync
Is your Lync client is installed with latest Patches?

Delaying the erase with the Write On behavior
Hey everyone.
Does anyone know how to delay the "erase" with the write on behavior.
When I apply the write on effect to my outline the behavior and set it to draw and erase. Motion draws the shape and as soon as it's drawn motion starts the erase the shape. I want to delay that erase and have the entire shape stay drawn for a few seconds.
I thought I could play with it in the keyframe editor but there are no options to adjust that specific ability of the write on effect.
Thanks.Hi,
this had me stumped for a bit too. All you have to do though is drag the start point of the shape to an earlier point in the time line. This will automatically drag the start point of the write-on behaviour with it (annoying!). Then drag the start point of the behaviour to a later point on the time line. (It will allow you to this independently of the start point of the shape as long as you drag it forward in time.) Now just reposition the shape on the timeline accordingly. Hey presto! - A delayed writeon/erase effect. Hope this is clear enough.

Mouse Cursor doesnt update until mouse is moved.
I think I'm having the same problem as the person in this post:
http://forum.java.sun.com/thread.jsp?forum=57&thread=149236
I'm setting the mouse cursor after certain buttons in a JPanel are pushed, but the cursor image doesn't actually get updated until the mouse is moved. I tried using Toolkit.getDefaultToolkit().sync() and that didn't work. The other solution, which was to fire a mouse event to force it to update, doesn't seem to be ideal.
Is there any other way to force the cursor image to get updated immediately, without moving the mouse?Hmm, I can't reproduce your problem (below is a small test example, that works fine with me) on win9x, neither with jdk1.3, nor with 1.4.
