JCombobox Strange Behavour

I have a JInternalFrame with some JLabels, JTextFields and JComboboxs.
I have set up all the desirable properties of this components, except from one.
I want when the jcombobox grab the focus the user have not to click with the mouse at the it (jcombobox)
in order to appear its choices.
Instead i want when press the "down arrow" to appear the list and when press the enter (when the lists of
the choices is appeared) to set this element as the selected.
Any help is appreciated!!

You could try something like
InputMap inputMap = combo.getInputMap( JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT );
inputMap.put( KeyStroke.getKeyStroke( "DOWN" ), "togglePopup");which should bind down to showing the popup. However, now you've got a problem because down
would normally move the selection down in the list -- what do you use instead?

Semie addivie measure and strange behavour

Hi,
For the first time , I 'm facing a strange behavior with a semi additive measure.
In EXCEL when I' m crossing it with a product dimension (Declared as Regular type ... no time type),
the behavour is like we are crossing with a time dimension.
No SUM on the column , but the last non empty value whenever appear.
Product Type - Product code Cummulative Power
A 16 <-- Problem we don't see No 31
AA1 15
AA1 16
Total SUM 16 !! no 31
Does anyone have an idea about this problem ?
Thank you very much
Christophe

Hi Christophe,
your question is not clear to me. From what I understand your facing problem with measure 'Cummulative
Power' which uses aggregation function 'Last NonEmpty'.
Don't know whether this will help. In our case 'Last
NonEmpty' function would be calculating 'Cummulative Power' against 'Product' dimension attributes,
while the measure value being the value of highest member or last member of time\date dimension. (remember semi additive measures always requires time dimension)
For example consider the following table.
Product
Date
Cummulative Power
A
20140101
10
B
20140101
15
A
20140102
13
B
20140102
17
A
20140103
16
B
20140103
11
Here if 'Last NonEmpty' function is used with Cummulative Power then against each Product we would get the following results in cube.
Product
Last NomEmpty(Cummulative Power)
A
16
B
11
i.e. the above values are corresponding to the last member of time dimension (20140103) .

10g Optimizer strange behavour

I think the Optimizer has a problem in 10g. (or in my installation)
Consider the following query:
Select field1 from table where keyfield = 'ABC' (this value only occurs 10 times)
This table has 30.000 records. If I put an index on keyfield the query tasks 5 sec. If I remove the index the query takes 1 sec. This is not logical.
This problem only occurs on 10g, the same query takes <1 sec on Oracle 8 or Oracle 9.
I think the Optimizer is having a problem analyzing the index. The analyzing step i think takes a lot of time (maybe 4 sec). Is this possible?
I already removed and added the index, created statistics, also set the optimizing mode to choose; always the same results.
Does anyone has a clue about this problem?

According to what you described you have an index on a column with around 10/30,000 values. When the index is in place the query takes 5 seconds; without the index the query takes 1 second. Sounds like a problem to me.
There are a few more things I would check:
Are you using histograms? They're designed for mixed-cardinality data to allow the CBO to dynamically decide when an index will help or not based on data values. I have seldom seen them used, but they can have an effect on queries when the histogram column value is hard-coded in the WHERE clause (bind variables don't work because histograms are considered before the bind variable value is examined by the optimizer).
Are you analyzing both the table and the index(es)? Are you using DBMS_STATS, which is supposed to be better than the ANALYZE command (I'm personally dubious for no good reason, but our DBA group swears by DBMS_STATS)?
There is a recognized problem with 10g called "bind variable peeking". the situation is that you run the same query twice with different sets of bind variables. The query is optimized for the first execution, but the values of the second execution are such that the query runs (with the first's plan) inefficently. This can be turned off with an undocumented intialization paramter.
I agree that the execution plans might be helpful to figure out what is going on.

SOFS, CSV available space changes daily, strange behavour

Hi, I have a a SOFS cluster which is working nicely, around 120 VM, running from 8 CSV volumes.
but I have noticed that the disk usage goes up and down during the day, one CSV only had 5% free when I checked this morning.
But overnight it drops back to 20-30% free. if I do a Volume refresh during the Day I can see the available space dropping, 1 or 2 Gig every hour or so.
now I though this was AVHD snapshots growing but I have checked this, and it not that causing the issue, I also thought it could be DPM, but no backups are running.
could it be memory of the VM's using extra disk on the VM config ?
I haven't noticed this behaviour before, and I am pretty interested in whats going on.
Cheers

Strange behavour of "People Recognition"

I've just installed Elements, and was looking forward to test the face recongnition. After install I marked some picures, pressed the "People Recognition" and it analyzed the images. Everything worked out fine.
Now, a few hours later", when mark some pictures and choose this feature it start the "Analysis". When the progressbar reach 100% it dissapears, and .. well thats it. Nothing more happens.
Anyone know whats going on, or how this can be fixed?

... you select some thumbnails and do Find > Find Faces For Tagging.
The progress bar appears, goes to 100%, and then progress bar
disappears. But the Organizer keeps running (it doesn't crash)?
Yes, this is correct. The same thing happens when I select only one photo. Organizer do not crash.
I should mention that "Generating thumbnails" is running in the background.

Strange behavour

Hi All,
I am using EAS and running the following calc script, for example, to clear one period of balance sheet:
//ESS_LOCALE English_UnitedStates.Latin1@Binary
Fix(@idescendants("Balance Sheet"), "2011","Forecast 12")
CLEARBLOCK ALL ;
ENDFIX
The script runs successfully, however retrieveing from Excel addin, the data is still there, and I run this couple of times, but data is still not getting clear. This is driving me nuts,
Any idea?

The add in and smart view do not cache data. Every retrieval should bring back a new retrieve. Unless you were timed out and you have messages turned off, you should be getting fresh data with every retrieve. The only other possiblilty I can think of is you are clearing Version12 If you are pulling a different version it could have data

Upgraded to windows 7 64 strange behavour CS4 Premiere Pro

Hi,
I upgraded to windows 7 64 and are using Premiere pro CS4 for the first time on this system.
I noticed when I click the minus sign (at the top right) to temporarily close the program the little icon shows up at the bottom of the screen like it does with any program on Windows 7.
But unfortunately when I try to let it appear on screen again nothing happens. I have to reboot the system to get it working again.
Also the timeline starts flickering when I play a sequence is this normal?!

I have an IPA2 wifi 3g working fine with wifi up for 3 monthes then from two weeks it get connection but after 1 minutes stop to serf/download with signal and connection always present. With the same router are still connected others 3 pc working!

I all,
the scenario is the following:
WIFI connection with TISCALI operator. Encryption made by WPA2 EAS with router SITECOM or tested also with another router DIGICOM with WPA TPK.
From December up to end of March the IPAD2 working perfectly serfing and downloading.
By two weeks it has a very strange behavour without have changed any configuration on IPAD or network:
with WIFI turned on it discover about 4 different ntw among them the mine, I successfully authenticate with psw the my ntw,
the IPAD2 start to run with Safari without problems, but after about 1 minutes, it stop to serf or download and answer that the Server cannot be reached or the page cannot be open, at the same time the signal is present on the icon of WIFI and it is strong.
This problem is systematic: If I dissasociate the ntw and then authenticate again I start to serf again for 1 minutes (more or less) and then it stops again, this occurs every time I authenticate the ntw after a disassociation.
I made some test changing the encryption from WPA2, WPA and also without encryption but the result was always the same, after about one minute the server seems to be for the IPAD2 no more reachable while the others PC and netbook connected to the same router continue to serf/download without problems!
I also tried to change the router with a DIGCOM that I did not use generally, but the behavour is always the same.
Since the IOS was the 4.3 revisin, I made the upgrade by means Itunes to IOS 5.1 succesfully installed.
But unfortunatelly all test repeted have had the same negative result with the same behavour!
Yesterday I tried to do the complete restore of the System but the tests had the same rsult.
I really don't know how to proceed, the problem started suddenly without any action from my side....is there someone that can help me?
Thanks Massimo

Legacy vs uefi

Hi all,
First of all I'm a new Lenovo user and realy love the hardware!
I have however a strange behaviour with UEFI on my new T540p. At least I think this is strange behavour for UEFI.
When I set the boot mode to UEFI it takes 8-10sec longer to boot than when I set it to legacy mode.
The difference in time is located between pushing the power button and the actual starting of windows. Loading windows itself takes equal time in both modes.
Latest Bios version is installed and all other bios settings are the same
By my knowledge UEFI should be faster to boot...
Any one else noticed this behaviour and or has a solution for it?
Many thanks
Solved!

Missing system font?

Hello,
please have a look at
screenshot.png.
The font in the property boxes (I don't know the exact name
of these elements) in DW 2004 is pixelized.
How could this happen? Which system font uses DW?
Greetings, Carlos

You can compare the fonts you still have to this list:
http://docs.info.apple.com/article.html?artnum=301332
If any of the critical system fonts are missing, you should be able to use something like "pacifist" to extract the missing fonts from your OSX install disks and replace them. Font problems can cause all manner of strange behavour.

Serious Flash bug?

Hello. I am a newbie to this forum, so I am sorry if this
message is off-topic. If it is, I would be obliged if anyone could
direct me to the correct place.
I am a veteran programmer but I am new to actionscript. I
have come across some strange behavour which is driving me mad.
Following is a part of my code :
...[snip]...
private var pnt:Point = new Point();
private var dirp:int;
private var fastp:int;
private var i:int;
private var pathB:Array;
...[snip]...
for (dirp=fastp; dirp<=i; dirp++) {
// BUG!!! If I UNCOMMENT 1 of the 2 following lines, code
gets mixed up.
// pnt.x=pathB[dirp][0].x+pathB[dirp][2].x;
// pnt.y=pathB[dirp][0].y+pathB[dirp][2].y;
pnt=new
Point(pathB[dirp][0].x+pathB[dirp][2].x,pathB[dirp][0].y+pathB[dirp][2].y);
if (addElement(pnt, dirp, pathB[dirp][2], pathB[dirp][3]+1))
return pathF;
As I mention above, if I uncomment //pnt.x=... or //pnt.y=...
or if I even replace them with something like pnt.x=pnt.x+1 ;
then my code gets mixed up and returns wrong results.
This is driving me nuts because these two lines shouldn't
have any effect since right below them there is
pnt=new Point(...);
which supposedly "cancels" the 2 previous instructions.
Right?
Could anyone, please, show me the obvious that I can't see?
Many thanks in advance,
Bill Kotsias

it's not necessarily a flash bug. there are situations where
assigning your pnt's x and y properties may trigger some other code
to execute and re-assigning those properties immediately afterwards
does not stop the other code from executing.
you need to isolate the minimum code needed to display the
issue before anyone will check it. you're nowhere close to that

PerfCounters mbean lazy loading ?

Hello,
I am using Weblogic 11g, running on Jrockit 1.6_20 on Windows 2008.
I have defined the flag -Djavax.management.builder.initial=weblogic.management.jmx.mbeanserver.WLSMBeanServerBuildr.
Now I am trying to monitor the value of jrockit.gc.mgr.oc.invocations of the oracle.jrockit.management.PerfCounters mbean, with CA Wily, and notice a strange behavour : the value of the mbean is not available until I open Mission control console to the server JVM!
I can wait for half an hour, but the moment I open JRMC, only then there's a value to this mbean attribute.
It's as if there are no instance of the mbean until it's queried by mission control, sort of lazy loading behaviour.
Has anyone seen this before? is this "branch" of the mbean tree indeed lazy loading ?
Thanks, Eli

I need your help here!

Qt development tools take a long time to load

Hello everyone! Since the latest qt update I have noticed that all the qt development tools (creator, designer, assistant, etc) take a really long time to load up and their behavior is sluggish at best (for instance menus take a while to show up). When I start designer from the command line I get this error
Qt at-spi: error getting the accessibility dbus address:
"Did not receive a reply. Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
Accessibility DBus not found. Falling back to session bus.
After this the application needs a solid minute or two to show up. Does anyone have an idea what the problem might be? Have you experienced similar behavior?

Same issue here after update to Qt5.
QtCreator with Qt5 starts a lot slower than before with Qt4.
Also i have notice another issue.
All commands that requires mouse double click such as:
> open a closed project's source/header/ui file
> browse files to add in resources
> select/edit resource item
> browse source files to add to project.
etc.
now all these commands activated by single click.
I solved that problem by recompile QtCreator against Qt4, and this strange behavour became past.
[EDIT] Also with recompiled QtCreator, the problem with slow startup solved too. [/EDIT]
Anyone have this problem too ?
Is this an issue related to Qt5 ?
