NaN when running, but not when debugging

Hello out there,
I am creating a JSP application with JDeveloper, and when I run the application the first time, it works without problems... but when I submit the values again to recalculate, the results of some operations that I'm doing are displayed as NaN.
Anyway, when I go to the debug feature, and start stepping over each line, and finish the program... the expected values are there! so I'm not able to figure out what's going on there...
any help will be highly appreciated.

Customized chrome works when running, but not when compiling ?

Dear webmates :
I have customized my chrome in Flex : it does not show the window container (transparent) , etc... and works great when I run it... however, when I compile it in order to have the standalone file... it simply works displaying again the window ! what do I have to do ? thanks in advance...

Hello,
When you built your installer, did you include all of the dynamically called VIs? The application builder does not know about dynamically called VIs unless you specifically tell it about them (which of course makes sense, as they are dynamic). Other potential issues might be the change in behavior of the Current VI's Path constant, or a lack of other dynamically called objects such as dlls or drivers. Make sure that the dynamically called VIs have been properly installed on your target computer in the desired paths. If that doesn't solve the problem then make sure that your application has good error handling capabilities (i.e. handles all error wires and eventually passes them to an error handler) so that you can use the error to determine which files are missing or in the wrong location.

Extension error while running but not during debug

Hi all, I'm using JDev 10.1.2 and I developed an extension for it. This extension guides the user to the creation of a sql file through a sequence of frames. While in debug mode, this extension works without the smallest problem, but when i restart jdev and I try using the extension, a problem arises. I made some experiments, it seems to be a problem related to the rendering of a table.
My question is: how can it happen that the debugger doesn't report such problem? And how can I discover precisely where the problem is?
I tried with some dialogs that give me information, but as the bug is in the rendering, this generates a loop.
I really don't know how to behave!!!Help!

Sound works when testing, but not when uploaded

I used the Behaviors pallet to stream my mp3 files, and it
works fine when tested locally, but as soon as I upload everything
and test it online, nothing plays. The site is
www.spidersandsnakes.net/media08.htm.
Any ideas?

I suspect this is where my issue lies, but I am not sure how
to fix it. I have attached some code that defines the image
location. I am able to successfully retrieve documents with the
following, is this the same type of scenerio,

except in the images folder ?

Not authorized when suspensing, but not when logged in from terminal

Hi All,
I have the following line in my inittab, to start an X server for the user "cedric"
x:5:once:/bin/su cedric -l -c "/bin/bash --login -c /usr/bin/startx >/dev/null 2>&1"
This works great, my X server is started during the startup of the rest of the services. when I then try to mouns an USB stick, suspend or reboot the machine, I get the message "Not autorized"
When I then kill X, login from a terminal, and then start X, everything works great, I can mount USB sticks, and suspend my machine from the lxde session without any problem, the message "not autorized" never comes up anymore
What have I missed in the iniitab line above? Is there a better way to autostart the X server? How can I debug these messages?
Best regards,
Cedric

2330 noise when talking but not when connecting th...

I have bought the 2330 three days ago
Its the second phone because the first one had a screen problem.
With this one the problem is that when i call someone i hear a noise from the earphone especially when iam at home or indoor places. Also the person that i call listens to the same or simillar noise.
The bizarre is that when i connect the hands free equipment everything is just perfect.
Anyone has an answer on that or has someone the same problem with me ??

I do not hear a noise on my 2330.
Is this your second 2330?
By the way, does your nokia 2330 have the correct time to the minute? My 2330 is slow by a 1 minute 37 seconds after the time is auto updated.

On switching on, a message says 'Firefox is already running but not responding...........' then tells me to close it and restart but how can I close it when the page isn't yet displayed?

When I switch on my computer I get the desktop then I try to click on Mozilla Firefox but get the message, 'Firefox is already running but not responding. To open a new window you must first close the existing Firefox process or resart your system.' I looked up how to close but I need to click on 'file' then 'exit'. How can I do that when I can't see the page yet? IE is working fine.

See also [[Firefox is already running but is not responding]]

When I try to start Firefox, I get a message that it is already running but not responding and I can't run another Firefox at the same time. I uninstalled and reinstalled. No change. Tried various other suggestions. Help!!

When I try to start Firefox, I get a message that it is already running, but not responding and that I should close it before trying to run another Firefox. But I cannot find a way to close Firefox program that is not running as far as I can see. I tried uninstalling and reinstalling Firefox, but that did not work. I've tried various other things, but no luck. I thought programs should stop when the computer is turned off, but that didn't work either.

How are you opening the Profile Manager?

Sounds that Firefox is still or already running.<br />
See:

Firefox stops loading new pages, displays "Loading". When I close it it goes. But when I restart it gives me "Another version is running, but not responding. This requires a power cycle reboot.

Version 3.6.18. Running on Windows XP Pro. (kept current)
This happens on a variety of pages. I get the little Loading thing in the tab, with the circle moving. So I X out (to exit Firefox). When I go to restart I get the error message "Another version of FireFox is running, but not responding". I give Windows the "three finger salute", and go to Task Manager, and do not see any reference to Firefox, and the Performance, and Processes seem OK. But it never seems to close the earlier Firefox, and won't let me open a new one. Any suggestions? Super Thanks for your help!

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

Am running Firefox 7.0.1 now. Normal memory usage is 157mb but when running Facebook (not running apps nor games), it goes up to 553mb Why?

Am running Firefox 7.0.1 now. Normal memory usage is 157mb but when running Facebook (not running apps nor games), it goes up to 553mb Why?

I encountered the same type of problem. Firefox running terribly slowly and slowing down my entire machine (Core i5 with 256GB SSD). Searching the forums, I found a couple of things about troubleshooting performance issues, one of which was to use '''hardware acceleration''', that is on by default. It was turned on on my PC, '''so I tried deactivating it, and it worked!'''
So doing the exact opposite as Mozilla support said solved the problem. It is really a pain now to work with Firefox. I'm using it because I have no choice, but I'd recommend IE and Chrome over Firefox... Whatever, the market will decide once Firefox has become to crappy...

Jar runs from Dos prompt, but not when double clicked.

Hello everyone,
My executable jar file will run fine when called from the Dos prompt like so: java -jar myJarFile.jar
But not when I double click it. I've associated *.jar files with java.exe as suggested here on the forums but all that happens when I double click the jar file is that I get an instance of the Dos prompt that flashes up on the screen and closes immediately. Any help or suggestions would be appreciated, thank you.
This short tutorial I found earlier may be of help to somebody.
http://www.cs.princeton.edu/introcs/85application/jar/jar.html

Yes Carmello, I had associated jar files via folder options in windows explorer with java.exe, now when I have the jars associated with javaw.exe as in the following:
ACTION:
javaw.exe -jar "%1"
APPLICATION USED TO PERFORM ACTION:
javaw.exe "%1"
I get an error dialog with the title string "Java Virtual Machine Launcher" and the error message itself is "Could not find the main class. Program will exit." when I double click on the jar file. As I said in my first post the application [GUI based with around ten different forms] runs fine when called from the Dos prompt. Any idea as to what is wrong? Thanks for replying by the way.

Not using any mouse pad, I have a very smooth desktop. But I just tried to use a sheet of A4 printing paper, but no result, the problem persisted.
Someone on this forum suggested, that USB3 may interfere with the magic mouse.
I have 2 LaCie HDD's about 70 cm away from the mouse, I use them on Thunderbolt. But in operation or not - the result is the same, the mouse plays up! Just now I was clicking the desktop and the mouse created a new folder!!
Thanks for the advice, Bee
Cheers, Gerd

Captivate 3 shows skin in preview but not when I run after published?

Captivate 3 shows skin in preview but not when I run after published. It shows it is included, what's up?

Is the Skin externalised? If so, perhaps Flash Global Security is interfering:

You could also try NOT externalising the skin.
