Firefox flickers during ADF PPR

Hi,
When a PPR event is fired on ADF page element, which sets values to other fields, the panel or page is going grey for a while before re-rendering. Did anyone face this? This 'flicker' is supposed to be firefox bug as per some forums. Also, this flicker is not seen on IE.
Thanks
Chinni

PPR causes a repaint, so in my opinion, if you put a partial trigger on the page component, then the page component is redrawn resulting in a flicker.

How to chage defautl ADF PPR behaviour for a component?

I have a heavy page with lot of text fields. On value change of any of this field I am sending a request to server side for calculation. On execution of this request, result is displayed to user. I am using PPR for this.
But my service execution is heavy and takes time. I need to allow user to change input when service is being executed on server side. However result should be displayed for the last request.
Is it possible to override the default implementation of ADF PPR? How to achieve it?
Is there any alternative to achieve this requirement?
I would appreciate any help!!

Right now for each request result text is updated. I need to show only result of the last request.
While changing field values, end user should not be displyed result generated for each request sent based on valuechange listner set on each of the field.

ADF: PPR in detail table gives a java.lang.ArrayIndexOutOfBoundsException

Hi,
I have an existing master-detail layout. To this I'm trying to add a second detail table.
My problem is this: If I set the ChangeEventPolicy of the iterator of the second detail table to PPR (which I believe I should do in order to have the table refresh with new details when I change the selected row of the master table), I keep getting a java.lang.ArrayIndexOutOfBoundsException.
Can anyone tell me what the problem might be?
Regards,
Andreas

Hi Amir,
It looks like the data model is okay; I found no problems when testing with the Business Component Browser. The relationship between the master and the detail works, and I get no errors.
When running the application and I trigger the error, the IntegratedWeblogicServerLog (I hope this is what you meant by stack trace) has this to say:

Firefox freezes during DNS lookup

On many pages, especially almost any eBay page, firefox gets part way through loading the page and then freezes. Sometimes it eventually finishes loading, but it may be after many minutes. The title of my question is because the firefox status bar always shows a message about looking up some URL during the freeze. I've tried safe mode, and it has no effect on the problem. I've checked for current updates of all plugins, especially Flash. Nothing changes this behavior.
Some web pages load without this effect. On the same computer, neither IE nor Chrome has any problem with the same pages that freeze Firefox.

can you try to reproduce this issue on Firefox 10?
* getfirefox.com

XP firefox9 I tried todownload a file and got a message about needing an application. Since then when I try to down load that file firefox flickers and multipe

Every time I go to the file that I got the message about specifying an application (which I'd never seen before) to download it, and I try to download it,firefox starts flickering and multiple entries appear on the task bar. ctrl-alt-del eventually stops it. I can download the same file no problem with IE but I prefer to use firefox. I have been downloading a similar file (torrent file for the daily show) for years without any problem.

I'm having the same problem with this, only it happens with all add ons. I get error -228 when I try, every time.
I can't install through the add-on manager, from the add on site, or by saving the link on the site. I've tried downloading it in Firefox, Chrome, and IE to no avail.
I can, however, drag existing .xpi files into the add on manager and they will install just fine.
I've looked through all the available other documentation, including the two links suggested by TXGuy above and none of it has helped.

Show Loading icon during long PPR request?

Hi,
I have a 11g taskflow that loads a bpel tasklist which can take some time to load when the user has a lot of tasks. The pagefragment shows the tasks based on a view object. The view object is filled by calling the bpel api over soap which can take some time (did not get the rmi client to work with weblogic). When the view object is filled the UI shows the fetching data text but during loading the view object the UI stays on the calling page and to the user it looks like the application is not doing anything when he clicked the show tasklist page menu item while in fact the page is still loading. Is there a way to show a status/loading icon/component when PPR is loading the pagefragment that contains the task list? The fact that loading takes some time is not an issue but now the user has now idea if there is actually happening something. Showing the loading icon that is rendered at application startup during waiting would be great .....
Kind Regards,
Andre

Hi,
try af:progressIndicator
" The progressIndicator component can be used to give users an indication that there is a back end task in progress. A ProgressIndicator's state is tracked by the org.apache.myfaces.trinidad.model.BoundedRangeModel attached to this component through its 'value' attribute. The BoundedRangeModel provides a 'value' and a 'maximum' to the component. If either the 'value' or the 'maximum are negative numbers, the progressIndicator is in an indeterminate state and shows up as a spinner animation. If the 'value' is not negative (and the 'maximum' is negative), the progressIndicator is in a finished indeterminate state and shows up as a stopped spinner. When the 'value' and 'maximum' are non-negative values, the component switches to a determinate mode and renders a progress bar indicating percentage of task completion ('value' / 'maximum'). Each of these various states will show a hover description for that state Once the task is complete, if an 'action' has been assigned to the progressIndicator, then an ActionEvent is triggered.
The progressIndicator component can be used with a poll component from the page as a partial trigger, in order that it be updated at regular intervals in PPR mode as determined by the pollInterval from the poll component. "
<af:progressIndicator id="progId" value="#{boundedRangeModel}" />
value: The data model being used by this progress component. The model should be of type org.apache.myfaces.trinidad.model.BoundedRangeModel.

Firefox: Flickering when scrolling - need help with clean 'new' install

Screen is flickering when scrolling (IE does not). I tried disabling add-ons and tried safe mode - neither helped. Running Win 7 Pro 64bit. Uninstalled via 'Programs and Features'. Download and reinstalled Firefox. Now it shows all my previous settings: menu bar, bookmarks bar, etc. Question: how did it get that stuff back if it 'cleanly' uninstalled? Question: how do I know it didn't pick up it's old 'bad habit' from the previous settings? I am an experienced PC user but not Firefox expert. Looking for help lest I have to ditch Firefox completely...

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
#Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows:
#* In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux.
#* In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
#In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
#In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
#Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Firefox crashes during startup

Hi,
My Firefox (v18.0b7 version) needed for specific web application accesses) suddenly crashes during startup.
I've tried remove/install again, same behaviour. creating new profile changes nothing.
Crash id : bp-880858a9-1110-4907-939b-a33e22141114
Could you help?
Thanks,
Thomas

OK, apparently something has been broken with my Software Center. Version 28.0 is pretty old, after all.
So I just launched Update Manager and updated everything to 14.04.1.
Now Firefox runs and displays 32.0 in its "About" dialog.

Using Firefox 7.0.1 & am trying to clear cache, because Firefox crashes during online college courses (Firefox 3.0 or higher is a supported school browser), and I keep getting an error message about 'Quick Time.' Using pc - Windows 7 Home 64 bit.

As soon as I open up Firefox - it crashes on me. It takes me at least two or three attempts. I downloaded Firefox from the Firefox website and also use it for Facebook. I am wondering if it is because I also alternate between using IE as well? While attempting to open my school e-text, a message popped up that if experiencing problems opening my e-text - then I should clear cache and cookies which I cannot do - because of the "Quick Time error message."

As you can see below, when I right click, I have no such option. In the User Account Settings, I'm operating as the "System Administrator".
Any other suggestions?

Cursor focus during a PPR event

Hi,
I have two messageTextInput columns (lets say text1 and text2) inside a table region. When a user enters a value in text1 and do a tab out, I fire a PPR event and set some attributes in my VO. The problem is: after it is done, the cursor focus does not move to text2, even though the user did a tab out after entering a value in text1. Cursor focus returns again to text1.
Also, I do not want to do a page forward, so that processRequest is called again. That would be a costly operation for us. Please let me know if there is a way to regain cursor focus to the right textInput bean.
Note: This is IE 7.
Thanks. Much appreciate your inputs.

Bogus web site pops up in FireFox tabs during use

I recently had some virus problems on my computer. I erased some registry entries, and Trend Micro confirmed that my virus problems were solved. However, shortly afterwards, tabs unexpectedly pop up in my FireFox browser. They all open to the same web site:
http://xn--czsp}ko!my {h-h-hta4h5c38e7b9i3da7xt65c0hf441y/
I then get a message from the browser:
"Alert The URL is not valid and cannot be loaded."
This happens as many as 4 times in a row.
Could you please tell me what is going on here, and what needs to be done to stop it?
Thanks!

Gee, I guess I have another problem. I clicked to upload a screen shot of less than 200K and the spinning wheel upload progress indicator appeared to be stuck. I tried a second time but it still just continued to spin so there's no screen shot available. Sorry.

Error during ADF Security logout in 12c

Hello,
I'm in the process of migrating my application from 11.1.2.4 to 12.1.2.0, and one thing I've noticed is the following error message in the weblogic logs when logging out of ADF Security:
<Error> <oracle.adf.share.http.HttpSessionScopeAdapter> <BEA-000000> <HttpSessionScopeAdapter: Request is in an invalid state. Could not access the request session.>
The logout still seems to work fine however. Currently I'm logging out with the following code (from here):
ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
ectx.redirect(ectx.getRequestContextPath() + "/adfAuthentication?logout=true&end_url=/faces/home");
FacesContext.getCurrentInstance().responseComplete();
Every time I press logout, the above error happens 5 times in the logs.
I've also tried using the logout code from the 12c documentation and that produces the same error, but interestingly only produces that error 4 times.
Is there something extra or different that is supposed to be done to log out of ADF security in 12c? I can't imagine that getting an error repeatedly is what should be expected.
Thanks!

Hello,
I gave that idea a try, and it was the same result as the very similar manual logout code given in the documentation I tried earlier: http://docs.oracle.com/middleware/1212/adf/ADFFD/adding_security.htm#ADFFD21669
The logout happens successfully, but that error message shows up in the logs at least once. Whenever I do a logout without going through the authentication servlet, the error is always logged exactly 1 time fewer. In my application I migrated from 11gR2 to 12c, the error would happen 4 times (5 through the servlet), and in the fresh sample 12c app I made earlier this week, it happens 1 time (2 through the servlet).
I should also add that all of this testing has just been done in the integrated weblogic 12c server that comes with JDeveloper 12c.

QuickTime flickering during Video Tutorials?

When I am watching the Video Tutorials for any of Apple products my QT flickers dark and light, not to the point where I can't see the video, but to the point where it is annoying. Anyone else having this problem? This is on a 4 day old new MacBook. I have the most recent version of QT installed.
Anyone else having the same issue?

MACBOOK QUICKTIME VIDEO PLAYBACK FLICKER ISSUE
Well, this is the first time I have been so far out on the front end of a new problem with a new computer purchase, so I guess I have the responsibility of raising the "noise level" on this defect. I certainly want a "fix" sooner rather than later.
After speaking to a relatively nice guy at Apple (Steve H.) last week, I did extensive diagnostics on my own, and sent a VERY long email to Apple explaining the problem in great detail providing information pertinent to engineers (along with affected video samples) in addition to sending in a "data capture file" of my new MacBook's status.
I later found out my diagnostic email was not forwarded to the engineers because of questions they sent back to me, indicating that they never got the detailed report after viewing my data capture logs.
Today I spoke with "Catilin" - not an engineer - (apparently the engineers are insulated from speaking voice to voice with customers). Caitlin informed me that since I did a clean install of the OS before one of my tests, that is proof that my video files are corrupt and there is no defect. When I then asked if it is possible that Apple could ship a faulty product, she answered, "No."
Sigh... where are the scientists of the world when you need them?
Anyway, for those of you out there with the problem, I will not post my long detailed report here. We all seem to be experiencing the same issues anyway. I just wanted to confirm that you are not alone, and apparently not a small number. When customer service tells you that you are the first person they have heard of with this problem (as they are mostly saying now), know that it means nothing. There are a lot of customer service people, and even widespread problems take time to be common knowledge among support staff.
Please make sure you tell customer service that this is a KNOWN ISSUE among users. Dozens of people are certainly contacting Apple about this problem now, but they have not yet issued an internal memo so that all customer service personnel are aware of it.
I will attach the latest email I just sent to Steve H., who just left me a cryptic voice mail message explaining how we should use third party software to play back videos and how we should use easily obtainable online apps to convert our video clips to other formats that might not be affected by the defect.
Please note that I am not trying to be negative about Apple here, but it would seem from my communications so far, only the engineers (scientists) are open to evaluating this problem rationally, and unfortunately I am currently forced to speak to the engineers through the filter of "not so highly intellectual or scientifically trained" customer service persons.
So, please spread the word when you call Apple and make sure they are aware that you have read about this problem from other Apple customers online.
I am tired of this issue and do not have another 20 hours to invest. I hope someone else will take a turn moving this problem forward with Apple and post your results here. Maybe if we work aggressively in shifts on this thing, someone in a position to do something at Apple will finally hear about it.
Steve,
I did not understand your voice mail.
What do you mean by, "There is not really much more we can do on this."?
Incidentally, it affects more than MPEG 1 files, as is evident in the detailed email I sent to you.
Did you mean to say, there is not much more you can do about it now, but it is being worked on?
Is it Apple's official position that this defect will not be resolved and we must always use third party software to play standard video clips (as suggested in your message), instead of using Apple's defective software shipping with MacBooks?
I must assume you misspoke in your email message.
Did you mean to say to use other programs and convert videos to other formats in the interim while Apple's engineers work on a correction?
Has it already been determined that all new Macbooks have the problem, or only some?
Obviously, if it is only some, I need to return mine to get a MacBook that does not have this defect/conflict/ or whatever it is.
I hate to say this, but as is evident by your just received voice mail and you not being aware of the different affected video formats I wrote about in great detail before, you are apparently another technical support person to go down in history as not paying close attention to an important and detailed diagnostic email before replying.
It is doubly surprising to see this behavior in you, when in my earlier email I went out of my way to explain and warn against this all too common and bizarre phenomenon of customer service persons not paying attention to helpful diagnostic email before replying to the treasured customers who went out of their way to prepare and send such email.
I can't keep working for Apple for free on this issue, especially when I am not receiving coherent responses to my testing and kind diagnostics work.
Please consider me retired from the "MacBook Development and Leopard Beta Testing Team", until such time as it is decided to compensate me adequately for my generously donated time.
Fix it, tell me to exchange for another unit, or tell me the problem has been acknowledged and it is being worked on. Or reiterate one last time that it will not be fixed (as you suggested in your last message) and I will know I must return the defective computer and consider other options in life.
I have no more time for any other responses from you.

Firefox freezes during various operations (scrolling, filling form fields, clicking through the options menu, etc.)

Almost any activity in Firefox is subject to brief freezing. The freeze lasts anywhere from (approx.) 1/2 second to 3 seconds. I searched online and I came across an article stating the freezes may be due to Anti-Virus software. The work-around presented was to set browser.sessionstore.enabled to false. The idea is Firefox does not attempt to write to a file, and so my AV software doesn't waste time checking if the access is valid. The change had some positive effect. The freezes now occur less often.
However, the freezes still occur every few seconds, still to the point of major annoyance. So what I did was run Process Monitor while Firefox was running to see if the freezes coincided with file accesses. Indeed they do.
I would like to know if I can change a setting which will cause Firefox to not access these files (or files like these) so often:
firefox.exe QueryOpen C:\WINDOWS\system32\msimtf.dll
firefox.exe ReadFile C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox\Profiles\k33hi6th.default\Cache\_CACHE_001_
firefox.exe LockFile C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\k33hi6th.default\content-prefs.sqlite
firefox.exe QueryOpen C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox\Profiles\k33hi6th.default\Cache\5ACD1B8Ed01
firefox.exe WriteFile C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\k33hi6th.default\cookies.sqlite-journal
There are hundreds of such accesses over just tens of seconds. These files are accessed while I'm e.g. scrolling down the page. I could understand if they were accessed while loading or drawing the page, but again this is occurring while I'm merely scrolling down the page and typing in this very text box!
