Method executes too early
Hey You
I call a method after a SequentialTransition block. The problem is, that the method executes while the SequentialTransition (takes about 10 seconds) is still running. Is there any possibility to execute them in order?
function myMethod(): Void {
SequentialTransition {
content: [
aTransition,
anotherTransition
}.play();
somemethod(); // executes to early
}Regards,
rethab
if you want your method to be invoked after the finish of animation then i think it's better to override stop() function of SequentialTransition which is inherited from javafx.animation.transition.Transition.

Chapter Markers End Jump Too Early-Problem
Folks, I am using DVDSP 4 and my chapter markers keep stopping too early from the burned DVD. When I play the Video_TS folder using Apple DVD player all is well. When I burn it and play it on a standard DVD player, all the chapter markers end jump earlier than they should - cutting off my full credit rolls on my video track.
All of my chapter markers came from Final Cut Pro where I initially made them.
Please advise.Make sure you test this on more than one player if it is a "for real" project of replication or duplication. All players are not created equal and there are the real weird things that may show up on only one or two players, but you need to make sure. You may want to try the other methods and see if it helps on the problem player just for fun. (Yeah, I know does not sound like much fun, but it is sort of interesting I guess )

TS4.2: VI too early to convert
Hi,
I'm getting the error -18002 VI too early to convert when I execute a TestStand 4.2 sequence file with the TestStand Base Deployment Engine. I created the Deployment installer with the deployment tool in TS4.2 and installed it on a second system. I added all needed LV runtimes and drivers incl. TestStand Deployment Engine. All installed softwares shown in the MAX are equal to the Developing system. But on the target system I always get the mentioned error. So I searched the NI Forum and found a similar Problem, but no real solution for that. I think, that the TestStand Base Deployment Engine on the target system chooses the wrong LV runtime engine, something higher then 8.2.1 (this is the version of the VI's). When I change the Labview adapter the the developing system to 8.6.1, I get the same error. But with 8.2.1, everything works fine.
How can I change the default LabView Runtime Version for the TestStand Base Deployment Engine?

[...]I need a something like the LabView Adapter (like in TestStand developing system) in the TestStand Base Deployment System.[...]
The TestStand deployment has also settings for Adapters. It is possible, that your UI does not supply you with the option to change those settings. You can always install the predefined UIs delievered with TestStand and run it on the deployment system. You can then change the settings for the LV Adapter as needed.
mtimti wrote:
[...]All my settings and software version are identical on both systems.[...]
If this is true, then the LV Adapter settings should already be correct. Therefore, there has to be another reason for this behavior. But please check the settings as described before.

[...]The whole problem started when we decided to change the TS version form 3.5 to 4.2. everything was fine with 3.5 and I thought I only need to deploy everything again and that's it, bau then came the VI version error.[...]
Never heared something like this. I asume that not only TestStand was updated in the process. Is it possible, that you have been working with something older than LV 8.2 when using TS 3.5? If so, please masscompile all VIs using 8.2 before deploying them.

Systemd: some services starting too early and then failing
Hello everyone,
I freshly installed Arch on this new laptop (Asus Zenbook Prime UX32VD) and from the start, I wanted to have a pure systemd setup. I'm using services only and I've uninstalled initscripts and so far it's working relatively well.
However, some services seem to start too early by default and the workarounds are unsatisfactory.
Problem 1: asus-screen-brightness and asus-kbd-backlight
On this lap top, the stock screen brightness buttons do not work (yet). A script and a service file (which are both available via the asus-screen-brightness AUR package) have to be used to allow users to change the brightness via the script. The problem is, with that service enabled, it only succeeds sometimes. About have of the time booting the laptop it fails, most likely because the necessary nodes in /sys/ do not exist yet. Restarting the service manually after booting does the trick:

Exactly the same problem occurs with asus-kbd-backlight.service which is needed to allow users to control the keyboard backlight. It also fails because of missing /sys/ entries if started too early.
Problem 2: automatic login & X11
I use the method described on the wiki to autologin into TTY1 with my user and my .bash_profile contains
[[ $(fgconsole) = 1 ]] && startx
and my .xserverrc is configured as explained in this fantastically useful article by falconindy.
This way, X starts automatically and my session is properly authenticated for things like udiskie. I'm not using [testing] but instead rebuilt polkit with --enable-systemd and it's working just fine. The problem is, just like in problem 1, Xorg fails to start every now and then, failing with
(EE) No devices detected.
I don't have a full log because it hasn't happened in a while, but I'm very certain it's because the chipset isn't ready, yet.
Solutions?
I added "i915" to /etc/modules-load.d/static.conf hoping that would cover both the Xorg and backlight problems but it doesn't help. I then tried adding i915 to my MODULES in mkinitcpio.conf and rebuilding the initramfs and at least it looked like that way the problems went away but it added about 4 seconds to the time spent by the "kernel" during boot which is quite unacceptable. (Plots with and without i915 in MODULES).
I read the systemd.unit and systemd.service man pages but I can't find a way to speficy required kernel modules for a service file. I'm not sure if specifying the modules in /etc/modules-load.d shouldn't be enough (because apparently it's supposed to load for sysinit.target, which is early) but apparently it isn't.
Any ideas how I can get these services to work properly without sacrificing too much boot time?
Thank you

How can I count a method executed numer of times.
Hi,
I want to count that a method executed particular no.of times. If it crosses N no.of times then i should print the count and i should reset the count to zero.
I have tried but i havn't get any idea to do it....Could you please give me some ideas to do it....
-Thanks in AdvanceThanks for reply....my requirement is...suppose i have a code with me...front end sends requests every time...if my code executes the request properly(Eg., a simple transaction) then it goes fine...if my code gets exceptions then i need to send a mail to particular persons...
It is fine till now.....But i should not send mails each and every time.....If my code rises exceptions continously some N no., of times within 5 minutes then i need to send mail.........
I hope you understood my requirement....I have tried for this one.....But I am not getting the solution.... -
Windows TCP Socket Buffer Hitting Plateau Too Early
Note: This is a repost of a ServerFault Question edited over the course of a few days, originally here: http://serverfault.com/questions/608060/windows-tcp-window-scaling-hitting-plateau-too-early
Scenario: We have a number of Windows clients regularly uploading large files (FTP/SVN/HTTP PUT/SCP) to Linux servers that are ~100-160ms away. We have 1Gbit/s synchronous bandwidth at the office and the servers are either AWS instances or physically hosted
in US DCs.
The initial report was that uploads to a new server instance were much slower than they could be. This bore out in testing and from multiple locations; clients were seeing stable 2-5Mbit/s to the host from their Windows systems.
I broke out iperf
-s on a an AWS instance and then from a Windows client in the office:
iperf
-c 1.2.3.4
[ 5] local 10.169.40.14 port 5001 connected with 1.2.3.4 port 55185
[ 5] 0.0-10.0 sec 6.55 MBytes 5.48 Mbits/sec
iperf
-w1M -c 1.2.3.4
[ 4] local 10.169.40.14 port 5001 connected with 1.2.3.4 port 55239
[ 4] 0.0-18.3 sec 196 MBytes 89.6 Mbits/sec
The latter figure can vary significantly on subsequent tests, (Vagaries of AWS) but is usually between 70 and 130Mbit/s which is more than enough for our needs. Wiresharking the session, I can see:
iperf
-c Windows SYN - Window 64kb, Scale 1 - Linux SYN, ACK: Window 14kb, Scale: 9 (*512)
iperf
-c -w1M Windows SYN - Windows 64kb, Scale 1 - Linux SYN, ACK: Window 14kb, Scale: 9
Clearly the link can sustain this high throughput, but I have to explicity set the window size to make any use of it, which most real world applications won't let me do. The TCP handshakes use the same starting points in each case, but the forced one scales
Conversely, from a Linux client on the same network a straight, iperf
-c (using the system default 85kb) gives me:
[ 5] local 10.169.40.14 port 5001 connected with 1.2.3.4 port 33263
[ 5] 0.0-10.8 sec 142 MBytes 110 Mbits/sec
Without any forcing, it scales as expected. This can't be something in the intervening hops or our local switches/routers and seems to affect Windows 7 and 8 clients alike. I've read lots of guides on auto-tuning, but these are typically about disabling scaling
altogether to work around bad terrible home networking kit.
Can anyone tell me what's happening here and give me a way of fixing it? (Preferably something I can stick in to the registry via GPO.)
Notes
The AWS Linux instance in question has the following kernel settings applied in sysctl.conf:
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.core.rmem_default = 1048576
net.core.wmem_default = 1048576
net.ipv4.tcp_rmem = 4096 1048576 16777216
net.ipv4.tcp_wmem = 4096 1048576 16777216
I've used dd
if=/dev/zero | nc redirecting to /dev/null at
the server end to rule out iperfand
remove any other possible bottlenecks, but the results are much the same. Tests with ncftp(Cygwin,
Native Windows, Linux) scale in much the same way as the above iperf tests on their respective platforms.
First fix attempts.
Enabling CTCP - This makes no difference; window scaling is identical. (If I understand this correctly, this setting increases the rate at which the congestion window is enlarged rather than the maximum size it can reach)
Enabling TCP timestamps. - No change here either.
Nagle's algorithm - That makes sense and at least it means I can probably ignore that particular blips in the graph as any indication of the problem.
pcap files: Zip file available here: https://www.dropbox.com/s/104qdysmk01lnf6/iperf-pcaps-10s-Win%2BLinux-2014-06-30.zip (Anonymised
with bittwiste, extracts to ~150MB as there's one from each OS client for comparison)
Second fix attempts.
I've enabled ctcp and disabled chimney offloading: TCP Global Parameters
Receive-Side Scaling State : enabled
Chimney Offload State : disabled
NetDMA State : enabled
Direct Cache Acess (DCA) : disabled
Receive Window Auto-Tuning Level : normal
Add-On Congestion Control Provider : ctcp
ECN Capability : disabled
RFC 1323 Timestamps : enabled
Initial RTO : 3000
Non Sack Rtt Resiliency : disabled
But sadly, no change in the throughput.
I do have a cause/effect question here, though: The graphs are of the RWIN value set in the server's ACKs to the client. With Windows clients, am I right in thinking that Linux isn't scaling this value beyond that low point because the client's limited CWIN
prevents even that buffer from being filled? Could there be some other reason that Linux is artificially limiting the RWIN?
Note: I've tried turning on ECN for the hell of it; but no change, there.
Third fix attempts.
No change following disabling heuristics and RWIN autotuning. Have updated the Intel network drivers to the latest (12.10.28.0) with software that exposes functioanlity tweaks viadevice manager tabs. The card is an 82579V Chipset on-board NIC - (I'm going to
do some more testing from clients with realtek or other vendors)
Focusing on the NIC for a moment, I've tried the following (Mostly just ruling out unlikely culprits):
Increase receive buffers to 2k from 256 and transmit buffers to 2k from 512 (Both now at maximum) - No change
Disabled all IP/TCP/UDP checksum offloading. - No change.
Disabled Large Send Offload - Nada.
Turned off IPv6, QoS scheduling - Nowt.
Further investigation
Trying to eliminate the Linux server side, I started up a Server 2012R2 instance and repeated the tests using iperf (cygwin
binary) and NTttcp.
With iperf,
I had to explicitly specify -w1m on both sides
before the connection would scale beyond ~5Mbit/s. (Incidentally, I could be checked and the BDP of ~5Mbits at 91ms latency is almost precisely 64kb. Spot the limit...)
The ntttcp binaries showed now such limitation. Using ntttcpr
-m 1,0,1.2.3.5 on the server and ntttcp
-s -m 1,0,1.2.3.5 -t 10 on the client, I can see much better throughput:
Copyright Version 5.28

8MB/s puts it up at the levels I was getting with explicitly large windows in iperf.
Oddly, though, 80MB in 1273 buffers = a 64kB buffer again. A further wireshark shows a good, variable RWIN coming back from the server (Scale factor 256) that the client seems to fulfil; so perhaps ntttcp is misreporting the send window.
Further PCAP files have been provided, here:https://www.dropbox.com/s/dtlvy1vi46x75it/iperf%2Bntttcp%2Bftp-pcaps-2014-07-03.zip
Two more iperfs,
both from Windows to the same Linux server as before (1.2.3.4): One with a 128k Socket size and default 64k window (restricts to ~5Mbit/s again) and one with a 1MB send window and default 8kb socket size. (scales higher)
One ntttcp trace
from the same Windows client to a Server 2012R2 EC2 instance (1.2.3.5). here, the throughput scales well. Note: NTttcp does something odd on port 6001 before it opens the test connection. Not sure what's happening there.
One FTP data trace, uploading 20MB of /dev/urandom to
a near identical linux host (1.2.3.6) using Cygwin ncftp.
Again the limit is there. The pattern is much the same using Windows Filezilla.
Changing the iperf buffer
length does make the expected difference to the time sequence graph (much more vertical sections), but the actual throughput is unchanged.
So we have a final question through all of this: Where is this limitation creeping in? If we simply have user-space software not written to take advantage of Long Fat Networks, can anything be done in the OS to improve the situation?Hi,
Thanks for posting in Microsoft TechNet forums.
I will try to involve someone familiar with this topic to further look at this issue. There might be some time delay. Appreciate your patience.
Thank you for your understanding and support.

Material Cost Estimate - Release too early
Hi,
I ran the cost estimate for one material on 12.06.2008 and i released the cost estimate. Here it is saying 'Cost Estimate released too early'. I thought system is releasing the cost for material for the next month. but i want to update the material cost for this month only.
And how many days before you have to run the cost estimate for the new month.
sateeshHi Sateesh,
Please check the period which you have mentioned in CK24.
I think the period you have given is of next month. Hence system is giving that message as next month's period may not have been opened.
System allows to release cost estimate only once in a period. Normal practice is to carry out cost run at the end of the month.
Please do let me know if your problem is solved.
regards,

Outlook displays date of birthdays one day too early in MS Office 2007, 2010 and 2013
Hi
We are supporting several clients that has issues with Outlook. Different versions of Windows, Office and different exchange server versions. Some contacts' birthdays
just "magically" changes to one day too early. I have done extensive research with no answer. I have experienced this issue personally as early as about 2005 or 2006 with a Windows Mobile PDA.
Our local time is GMT +2 without daylight-savings. I have checked the settings in Windows (Vista Pro and Win 7 pro
x86 and x64) and the calendar settings, I have reloaded a couple of pc's, created new profiles, installed new server hardware with newer exchange. Even tried a few off-the-wall ideas like resetting all views to default.
Some users' address books are shared, some not. Some uses Apple, Android, BB or Windows phone, some don't. Some connects through VPN, some don't. Some uses
AVG, Avast, Eset Nod, Forticlient, Mcafee, etc....
I have been fighting this problem for months, and can find no conclusive answer that resolves this.
If I manually open the contact and rectify the date, it will stay correct for a very random time period and then shift
again.
I am about to lose a couple of my biggest clients, and probably my job as well, so I need urgent help.
Please no remarks on OS version, Office version or mobile devices, as this is definitely not the issue.
HELP!Hi,
Have the users check on OWA, does the issue persist? Please also make sure the timezone of Exchange is also properly configured.
I'm not an expert about Exchange, I hope this blog can be helpful:
http://blogs.technet.com/b/fun_with_powershell/archive/2013/04/30/where-is-the-time-zone-property-stored-in-exchange-2010.aspx
To further dig the problem, rectify the date on owa and drop Outlook for a while(or one day), check the result the next day if the problem will come back.

Error:Work item 000000001099:Object FLOWITEM method EXECUTE cannot be execu
Hello experts,
I have created a Sales order workflow whr after creation sales order will go to 1 person inbox and he will check the SO thoroughly and thn i hv added a user decision step for APPROVED or REJECTED for same person.
Now after creation of sales order it goin to the person inbox for checkin SO but when he is saving it thn decision screen with button APPROVED or REJCTED is not coming and m getting error :Work item 000000001099: Object FLOWITEM method EXECUTE cannot be executed. and error: Error when processing node '0000000024' (ParForEach index 000000)
i checked the agent mapping for both step....and thr is no error in agent mappin...in both steps i have mapped same rule with responsibility IDs
PLz suggest urgently wht can be cause of error.
Regards
NitinHi Nitin,
I think this seems to be an agent assignment issue.
To debug this issue go to the workflow log and check if the agents are correctly being picked by the rule or not. Simulate the rule and check for the agents being picked.
In the workflow log, check the agent for the User Decision step. If there is no agent found then there might be some issue with the data passed to rule.
Hope this helps!

There is one block step before the transformation step...in which exception is not given...?can this be the cause??
Does it mean...you have a Block step in your BPM and your Transformation Step is placed in it....the Block should have an exception handling branch...have the exception handling logic as per your need....the Block step needs to use Exception Handler...same Handler to be used in the Transformation Step's System Error section.
Press F7 and check if your BPM is giving any warning message.

Recording starting too early and also ending too e...
Another problem.....
When recording programmes I am frequently finding that the recording is starting way too early...5-10 minutes....and often ends too early (very annoying as one misses the end of a particular programme).
Any help, gratefully received!
ThanksRecording should start 2 minutes before the scheduled start time and end 5 minutes after the scheduled stop time (by default - you can increase this).
The box won't automatically cope with programmes which start late. Are the programmes you're having a problem with starting on time?
Is the time displayed on the box correct? -
It seems that since the last update to I Tunes some songs are ending too early (30 to 1:30 too ealry). The get info button does not indicate the songs should end early. When i download the song again, the problem stops.
There could be a number of causes. If the iPod only plays a very short part of the file <10 secs this is usually down to problems with the structure of the file that iTunes can cope with but that causes the iPod to bail out. Re-encoding in iTunes will normally help, ie. re-rip or convert from MP3 to AAC or vice versa. Since all transcoding is lossy you should retain your original file as a backup in the hope that future firmware upgrades will fix this issue. iTunes also has a feature to allow you to exclude parts of a song from being played. Use *Get info* on a song in question and look at the Options tab. There are options here to set a start & stop time and to remember the playback position. Setting any of these will affect what gets played each time the track is selected. Finally, if you're playing songs in random order that are part of continous play albums the exact point at which the track stops may not be quite where you expect it to be.

PravinHello, and Welcome to the HP Support Community! As with any Internet Forum, you have to realize that you are visiting a "hospital" - most folks here are the minority who have had problems. If one was to judge the human race by visiting a hospital, you might run outside screaming "WE'RE ALL DOOMED! EVERYONE HERE IS SICK!!!" Those who have no issues at all do not come here and check in. The few that actually do come by and offer compliments are far and few between, and they are greatly appreciated by us! I've asked HP about Win10. They will not provide an answer until the final release is out. It could run with zero issues, or not! The Sprout is an amazing device - a large touchscreen All In One computer with some cool options not many other PC's could ever do! Is it too early? I've had one for almost a year (a loaner from HP for my participation here). Glitches? A few that were easily remedied. The decision is up to you. If worried about Win10, then wait a month or two. The device runs fine on Win 8.1. Why change to Win10? WyreNut

Abap proxy method execute synchronous
hey guys,
im new at XI and am posting this thread in the hope that someone would explain to me, what is required of the method "execute synchronous" in an abap proxy.
thanksHi,
<b>Execte_Synchronous</b> is used to send the message synchronously. Similarly execute_asynchonous is used to send the message asynchronously.
<b>Some theory about proxy.</b>
1. Proxies can be a server proxy or client proxy. In our scenarios we require proxies to send or upload the data from/into SAP system.
2. One more thing proxies can be used if your WAS ≥ 6.2.
3. Use Tcode SPROXY into R/3 system for proxy use.
4. To send the data from R/3 system we use OUTBOUND PROXY. In Outbound proxy you will simply write an abap code to fetch the data from R/3 tables and then send it to XI. Below is the sample code to send the data from R/3 to XI.
REPORT zblog_abap_proxy.
DATA prxy TYPE REF TO zblogco_proxy_interface_ob.
CREATE OBJECT prxy.
DATA it TYPE zblogemp_profile_msg.
TRY.
it-emp_profile_msg-emp_name = 'Sarvesh'.
it-emp_profile_msg-empno = '01212'.
it-emp_profile_msg-DEPARTMENT_NAME = 'NetWeaver'.
CALL METHOD prxy->execute_asynchronous
EXPORTING
output = it.
commit work.
CATCH cx_ai_system_fault .
DATA fault TYPE REF TO cx_ai_system_fault .
CREATE OBJECT fault.
WRITE :/ fault->errortext.
ENDTRY.
Receiver adapter configurations should be done in the integration directory and the necessary sender/receiver binding should be appropriately configured. We need not do any sender adapter configurations as we are using proxies.
5. To receive data into R/3 system we use INBOUND PROXY. In this case data is picked up by XI and send it to R/3 system via XI adapter into proxy class. Inside the inbound proxy we careate an internal table to take the data from XI and then simply by using the ABAP code we update the data inot R/3 table. BAPI can also be used inside the proxy to update the data into r/3.
I hope this will clear few doubts in proxy.
