ListView: reusing ListCell's after changing the ObservableList

When the size from an ObservableList, attached to a ListView, changes (add(), delete(), addall(),...), existing ListCell's are revoked and replaced by new ListCell's.
The old ListCells are still registered as ListChangeListeners until the GarbageCollector removes them.
By changing the ObservableList several times, the list of observers grow and grows.
The old ListCells are invoked every time by the change-event from the ObservebleList, causing them to be reloaded etc.
When ListCells do something like loading FXML, these behavior is causing serious performance problems, caching gets nearly impossible.
Why does the ListView revokes the old ListCells, when the ObservableList's size is changing ?

I've submitted issues related to this behaviour, and I think they are being fixed in JavaFX 3.0. This won't help us much for 2.2 though...
See for example: http://javafx-jira.kenai.com/browse/RT-20616

No effect after changing the message mapping

Hi everybody,
i'm using PI 7.1. After changing the attributes in my message mapping i can no see any effect in my result.
Should it be a cache problem? Where can i delete the caches?
regards,
Sid

Hi,
I guess there can be two things.
before going to the tcode sxi_cache...
Please go to the IR, Click Environment, Cache Notification and then select author as your id.
Now see if any are in red status. if so click on the change and click Repeat Cache Notification.
Now press refresh.
I guess this will resolve your problem

ORA-12545 error after changing the host name as IP address in Tnsnames.ora

HI,
I tried to connect PHP and oracle in Red Hat linux. I got error ORA-12545 after changing the host name as IPAddress in Tnsnames.ora file. In sqlnet.ora file also i have entry for tnsnames in Directory_Path. I struggled so much but i couldnt solve that. Please give me ur valuable suggestions....

12545, 00000, "Connect failed because target host or object does not exist"
// *Cause: The address specified is not valid, or the program being
// connected to does not exist.
// *Action: Ensure the ADDRESS parameters have been entered correctly; the
// most likely incorrect parameter is the node name. Ensure that the
// executable for the server exists (perhaps "oracle" is missing.)
// If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the
// host name to a numeric IP address and try again.
Seems you specified wrong IP address.

Concerning Epson Printer 4880: after changing the Ink from Photo Black to Matte Black I'm not getting the Epson Software in Photoshop and Lightroom. I can not select the paper medium, I don't see my profiles. What is wrong?

Concerning Epson Printer 4880: after changing the Ink from Photo Black to Matte Black I'm not getting the Epson Software in Photoshop and Lightroom. I can not select the paper medium, I don't see my profiles. What is wrong?

That is priceless!!! Thanks! I sure needed a good laugh after spending/wasting hours & days trying to either get my c6280 to give up on its Ink System Failure fixation, or find a decent replacement. Unfortunately I need the Smart Web Printing feature that I guess only HP has, or I'd try a different brand. And now even HP has very few models with that available.
My error msg is a little different from those previously stated, but close: 0xc18a0201. Even tho there were frustrations with my c6280, I did like several of its unique features which are hard to find now under $100. I hate how HP (& I suppose other brands also) are CONSTANTLY changing models & then of course ink cartridges.
Oh heavens, I've had the c6280 a whopping 2 1/2 years! I'm sure they want us poor slobs to have to buy a new one every year & a day! To say nothing of the exorbitant prices for ink. And now if this one is really dead in the water, I have SIX unused #02 ink cartridges which I cannot return---I got them in a combo pack, & for some reason have wound up with THREE lite pink & THREE lite blue cartridges, while having to buy extras of the other colors, that ran out before the others!!! Yeah, & what's with that not being able to print in BLACK if a color runs out????
Anyway I really loved your essay! It's a classic! And says it all! I hate that we have to be 'slaves' to the electronic 'wonders'!!!

Interface getting failed after changing the Business system to that service

Hello All,
Our Env... is XI 3.0 and this is related to produciton env.
Based on our client requirment to change the business system from client 871 to 100 for one of the R3 system which is reciever type(rfc).
After doing all the necessary changes , that particular service is getting failed and in the CC monitoring for that service I can see the log as "RFC_ERROR_LOGIN_FAILURE" mandate 871 (earlier client) does not exist in the system.
The steps which I have followed to change the Business system.
1>I loged into the SLD of PRD system and clicked on businsess landscape .then i have clicked on the specified system to be changed (RY1 ) and then clicked on change mode and selected the required client (100) and saved the settings.
2>I have logged into ID(Integration Directory) and selected the service (RY1) which need to be changed .Under service -->Adaper specific -->compare sld configurations and then clicked on apply changes.
3>Now selected that communication channel of service (RY1) RFCRecieverR3 and changed the client 871 to 100 and the password of user XIRFCUSER ...
Then i saved the changes and after that i have activated that interface.
After that when i logged into CC monitoring and viewed that service channels and see the following errors:
Receiver channel 'RFCReceiverR3' for party '', service 'RY1'
Error can not instantiate RfcPool caused by:
com.sap.aii.af.rfc.RfcAdapterException: error initializing RfcClientPool:com.sap.aii.af.rfc.core.repository.RfcRepositoryException: can not connect to destination system due to: com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Mandante 871 não existente no sistema (selecionar mandante existente)
Can any one help me out of this situation , and i need to fix this ASAP as this is production system.
Awaiting for your reply.
Best Regards
Rakesh Reddy

Hello Nisar
Thanks for the update,
Let me say few points about this particular problem:
1>The interface "XX" from XI sends data to two systems( R3 -->RP1 & RY1), some thing like branched (same data is passed to both the reciever systems).
And the second RY1 is copy of First system RP1 (Production sys) which is used for data loading purpose and every week there will be a refresh from First sys (RP1) to Second(RY1).
2>Now the first sys(RP1) is recieving the data successfully from XI , and the second one (RY1) is getting failed .And this started after changing the Business system 871 to 100 .
3>As mentioned by you , I have checked all the points mentioned
    i)In SM59 for XI (ABAP part) two rfc's are maintained (LCRSAPRFC & SAPSLDAPI) and the test connection is also fine...But I did not find these two connections in reciever systems(RP1 & RY1 too).
   ii)In reciever system RY1 ,when i went to RZ70 , i did not noticed any special settings and SLD Bridge :Gateway Information is not maitained over there .and the same thing in other reciever system(RP1) , with this can we confirm that there is nothing wrong in RZ70 settings.
   iii)In SLDAPICUST at recievers end for both systems nothing is mantained , where as in XI system all the details are maintained(Host name,port, user & password).
I have translated the error log into english from the CC monitoring for this interface which is in portuguese language .
It says that:
RFC_ERROR_LOGON_FAILURE: 871 Mandante not in the system (select principal existing)
Kindly advise me what to do ..for fixing this problem(this is pretty urgent and it is production env...)..
If any information required , I can provide that.

After changing the context path, felix console, I can not checkout content via vlt.

Hi everyone,
I have the following issue. After changing the context path, via felix console, I can not checkout the content via vlt. Before that, I could checkout without any problems.
I am using CQ5.5, CRX2.3, context path: /Test
That is what I am trying:
vlt -v --credentials admin:admin co http://localhost:23310/Test/server/crx.default

vlt --credentials admin:admin co http://localhost:23310/Test

To verify if I could connect to the instance properly I started CRXDE
and try to connect to "http://localhost:23310/Test"

MG3100 Cannon Printer, after changing the black prints misallied, and I have manually aligned??

After changing the black ink cartridge on my Cannon MG3100, when I print word and from the internet the prints are all misaligned and I have manually done the print head alignment, print alignment values, cleaned the nozzles, cleaned elements and clenaed the roller. I even brought the ink cartridge back to Staples thinking it was defective, but it still will not print correctly, does anyone have any answers please? Thank you! DD

Hi DD,
If you have replaced the ink cartridge with a Canon genuine ink cartridge and have already performed both automatic and manual print head alignments as well as cleanings and are still experiencing alignment issues, the printer will require servicing. Please Contact Us for your servicing options.

I can not get my mouse to work after changing the batteries

I can not get my wireless mouse to work after changing the batteries

Some ‘dumb’ questions just so we don’t assume what you have done:
Batteries installed with both + poles pointing to the top as you hold the mouse?
Mouse switch has been returned to the ‘on’ position - do you see a green light? First it will be solid green and then flashing green as the mouse tries to pair with the computer.
Try clicking the mouse a few times as it’s trying to pair.
If you don’t see a green light, try wiping off all battery contacts and reinserting the batteries. If still no green light and the mouse switch is ‘on’, are these old rechargeable batteries that been recharged many times or are they fresh normal batteries (not rechargeable batteries)?

My canon sx120IS continues to show low batter and shuts off even after changing the batteries.

My canon sx120 is continues to show low battery and shuts off even after changing the batteries. Any suggestions? Do I need to send it for repair somewhere, and if so, where?

My vi is writing just the same data into spreadsheet even after changing the loop iteration time. hw can I change this mode ?

My VI is writing the same amount of data into spreadsheet file even after changing the for-loop iteration time

You should post the VI (with appropriate values saved as default) to this thread. (At least a JPEG or PNG screenshot).
Inside the For Loop, right-click on the N terminal and create Indicator. Run the VI and you will see how many times the Loop spins.
Further guessing: You may have a 2D array with two rows and many columns feeding the For Loop.
