Very strange behaviour and exception with af:tree

Hello,
I deployed an ADF taskflow (which contains a af:tree) inside Webcenter portal...
When I add this taskflow to a page, the tree renders fine.. But when I expand a node (which contains just one element under it) and then collapse it and switch to a different tab, I am getting a Null Pointer Exception..
Attached is the log information
java.lang.NullPointerException

To make the problem more clear, if I collapse every node of the tree as last operation and then click on a command link (which should redirect me on another page), then the following happens according to the value of the "immediate" property of the tree:
1. If I set the immediate ="true" on the tree it does not throw this exception. But if the last action in the screen is collapsing a node and I click on any other action (clicking on a different tab) it does not trigger the action. But if I click on the same action once again, then the action is triggered successfully and things work as expected again.
Basically, it looks like if the last action in the screen is collapsing a node, then we have to click on a action (like clicking on a tab) twice for the action to be triggered.
But if I set the immediate="false", then it throws the null pointer exception.
2. if immediate = "false" I get an exception, and the application crashes:
Any help would be appreciated. Using Jdev 11.1.1.6.

Any suggestions, pls

Very strange behaviour of RGBImageFilter class

Hi!
I found very strange behaviour of RGBImageFilter class and problem is
that I need to solve that problem :/ So, situation is next:
I decided to use filtering process for collecting information about
image. So, I extended my own class from RGBImageFilter and overwrite
filterRGB( ... ) method ( everything is absolutely the same as in
documentation ) and also added my own code for 'no matter what'.
This code changes some class variable and my idea was to read those
variables after filtering process end, but... Suddenly I realized that
those variables, many times changed while filtering were performed
( I checked it ) after filtering gave the same value as in constructor!
The only one clue and idea about what happened is that class instance
were cloned and then executed, but thats not a functionality I was
searching. :/ I made some example of that 'effect'.
Image file name goes in command line.
Please pay attention on -3 value on exit: Filtering works, count growing
( just uncomment setPixels() method to see it ) but, but...

Populate List from Database (Very Strange Behaviour)

Dear Fellows,
I have developed a from which has two lists One for Major (say) and Other for Minor (say), thesr minors are based on the value of Major.
Now I have developed this system on Windows XP Professional, Developer/2000 6i and Oracle 8i (release 8.1.7).
Major list is populated from database and it shows all major values now using 'when_list_change' trigger the minor list is populated from the database based on the value of major list. Interestingly enough it is working fine without any problem.
Now I have deployed the software to Windows 2000 Professional/Server (tried on both), Developer/2000 6i and Oracle 8.0.5, but strangly the lists are not working now. First list (major) is still working but the other dependent lists are not working.
Another strange thing is that it populate the second list for one particular value (only at times).
The logic is that I have used a program unit to which i am passing 'list element' and 'query' and call it for each list in the when-list-change trigge.
Now its a very strange behaviour, I don't know what to do?
Your cooperation will be highly appreciated.
regards.

Hi,
I have Nokia N8 (a great phone, btw) with Symbian Anna. I wanted to download the maps. But the PC Ovi Suite is just busy forever, without downloading anything (I used Performance Monitor to find out it was doing nothing for hours).
As I have unlimited data plan from my phone, I decided to try updating directly from the phone instead. It successfully downloaded the list of maps, but when I selected one of them
"No Wi-Fi network available. Please configure a WiFi access point in the phone Internet destination settings."
Why should I do that? I have a working connection on that phone (as evidenced by the successful download of the list of maps). So now, I am stuck. How can I download the maps?
Well, the suggestion is there. Use a router.

Very strange behaviour master-detail-detail please help
Hello,
I have a parent-child-grandchild report which show's some really strange behaviour.
The data template has 3 queries Q1, Q2 and Q3.
Q2 is bound to Q1 using a bind variable
Q3 is bound to Q2 using another bind variable
For a certain record in Q1 the output should be
2 records in Q2
and 1 record in Q3 for each record in Q2
Q1 record
Q2 record A
Q3 record AA
Q2 record B
Q3 record BC
The results conforms to the expected output.
For another record in Q1 the output should be
2 records in Q2
and 2 records in Q3 for each record in Q2
Q1 record
Q2 record A
Q3 record AA
Q3 record AB
Q2 record B
Q3 record BC
Q3 record BD
In stead of the expected output, the result shows
Q1 record
Q2 record A
Q3 record AA
Q3 record AB
Q2 record B
Q3 record AB
For another record in Q1 the output should be
5 records in Q2
and 2 records in Q3 for each record in Q2
Q1 record
Q2 record A
Q3 record AA
Q3 record AB
Q2 record B
Q3 record BC
Q3 record BD
Q2 record C
Q3 record CE
Q3 record CF
Q2 record D
Q3 record DG
Q3 record DH
Q2 record E
Q3 record EI
Q3 record EJ
In stead of the expected output, the result shows
Q1 record
Q2 record A
Q3 record AA
Q3 record AB
Q2 record B
Q3 record BC
Q3 record BD
Q2 record C
Q3 record CE
Q3 record CF
Q2 record D
Q3 record DG
Q3 record DH
Q2 record E
Q3 record DH
So for the last record of Q2 I don't get the appropriate records from Q3 when there are multiple records to be shown, but only the last record which belongs to the previous Q2
What is going on?

FOR i IN (statement) LOOP - very strange behaviour

Hello, I'm experiencing very strange behaviour in my 9i Development Environment:
If I run this select from SQL Plus a I get six month with number of days:
select to_char(add_months(trunc(sysdate,'month'),rownum-1),'Month-YYYY') tmp_date, add_months(trunc(sysdate,'month'),rownum)-add_months(trunc(sysdate,'month'),rownum-1) colspan from dual a connect by level <=6
But if I try to cycle through it in PL/SQL I only get the first row.
FOR i in (
select to_char(add_months(trunc(sysdate,'month'),rownum-1),'Month-YYYY') tmp_date, add_months(trunc(sysdate,'month'),rownum)-add_months(trunc(sysdate,'month'),rownum-1) colspan
from dual a
connect by level <=6 )
loop
-- print something out
end loop;
Any ideas why does this happen this way? If I use a query that does not contain CONNECT BY it works ok.

Hi
Just change as given below:
FOR i in (
select * from (select to_char(add_months(trunc(sysdate,'month'),rownum-1),'Month-YYYY') tmp_date, add_months(trunc(sysdate,'month'),rownum)-add_months(trunc(sysdate,'month'),rownum-1) colspan
from dual a
connect by level <=6 ))
loop
-- print something out
end loop;

Error in drag and drop with a Tree component

Hello, everybody.
I'm doing a drag and drop with two trees.
But, when I drag from a tree to another show this error:
"oracle.job.RowNotFoundException:JBO25020: View line of oracle.jbo.Key[4.4] key not found in ViewTreeNodeRepository13_71."
Besides that, in my property SelectionListerner, when I have this line: "#{bindings.TreeNodeRepository.treeModel.makeCurrent}" there is a warning that says: "Reference makeCurrent not found".
Anyone can help me?
Thanks!

Hi,
+Besides that, in my property SelectionListerner, when I have this line: "#{bindings.TreeNodeRepository.treeModel.makeCurrent}" there is a warning that says: "Reference makeCurrent not found".+
Don't worry, its a designtime warning because the EL cannot be resolved. MakeCurrent is a method on the FacesCtrl binding equivalent to ADF, which is applied at runtime and not available at design time
+But, when I drag from a tree to another show this error: "oracle.job.RowNotFoundException:JBO25020: View line of oracle.jbo.Key[4.4] key not found in ViewTreeNodeRepository13_71."+
In drag and drop, ADF Faces performs the drag. However, the rest of the drop handling is up to the developer. Without any more information of what yur drop handler is doing, this question cannot be answered

Strange behaviour msi 7236 with e7400

Hello,
Is the msi-7236 supporting the e7XXX Intel c2d family ?
I've just switched from an e6400 to an e7400 and I've noticed some strange behaviours, mainly
the fact that the performances are the same with both processors ( and even a bit reduced with
the e7400 ! ).
Another big problem is in the bios CPU configuration section: instead of 6 options + C1E hidden features
there is only 2 + the C1E hidden features. Consequence is simple: impossible to setup Intel speedstep or
the other common options.
Additionally there is also a problem when displaying the frequency at the boot-time ( it displays 346xx MHz !)
and in cpuz, the coefficient displayed is 6 ( instead of 8 I guess for this entry level cd2 model)
As the latest msi 7236 bios is now 2 years old (v3.7), I guess this is the motherboard which is
responsible for this weird behaviour.
So anyone can help me with theses questions ?

945P Neo3, bios is version 3.7, to be accurate, internal nomenclature is 'MS 7236 revision 2.2'.
With ChristalCPUID I've succeed into putting the coefficient @10.5 so now the performances of the e7400 are as I was expecting, but the bios is still initializing the CPU with the lowest coeff.
Advanced features (64 bits instructions, SSE4 ,speedstep etc) are still not recognized.
I've also noticed that the e7400 is not listed on the 'officially supported CPU list' motherboard webpage.
How can it work partially without system failure ?
Would it be possible that 45nm are supported by this (old) MotherBoard even if it's not clearly specified by MSI ?

Very strange Issue, and cannot find a reasonable solution or Tech Support help / Will PAY for HELP !!

So, without going into great details that cannot reasonably be explained, the scenario goes a little like this:
When editing a PDF, and with nothing else open on the computer, Adobe Acrobat Pro XI tends to "hang up" and become unresponsive. The only plausible solution is to force command and restart Acrobat in hopes it will open correctly the next time. Sometimes this works, other times - nope .. Does not resolve the problem. So - can anyone recommend a solution? I have contacted help and they had to to delete a Adobe Preference file, and this seemed to work while I still had them on live chat. Once offline, it happened again.
Here is the really weird thing, I thought that I fixed the issue (as I am doing this for my boss on his Macbook Pro) and was able to quickly edit a PDF .. but when I handed the computer over to him - literally in only 2 minutes - he proceeded to edit the same document and was not able to. He got the never ending rotating circle of death
So - that is problem #1
Problem #2 is with the inability my boss has to use CC offline. I have personally reconnected to our CC account and verified all settings, and when I perform my tests at the office, everything seems fine and all programs work as should. However, he is now on business travel and says the "Trial Expired" keeps popping up. What is going on? This is literally frustrating him and me with what little knowledge I can assist with resolving the trial expired issue. How many days can you be offline with CC? Tech support says up to 99 days .. Clearly 4 days is ridiculous and I am not able to duplicate the scenario when I have his computer but what would it work for me and not him?
I just need to resolve this whole Adobe Acrobat issue as to finally get it resolved and fixed once and for all.
BTW, called in outside computer help from a local company - and the computer guy was working to get it fixed, but it seems even with live chat or phone support - it has now been escalated to Tech Support 2 .. This make any sense or logic? I believe he has uninstalled and reinstalled Acrobat and now it is only creating more issues. I think he tried to install a trial version and activate the subscription but it failed.
Any HELP? We are desperate and I'll even pay via PayPal to get a resolution to this problem if any recommendation leads to a solid solution. Guaranteed !!

Actually I also noticed that usual heat with wifi and game play.. However this was extreme heat. I wasn't able to hold it for long time and had to drop it.
So can that bulge can be ignored and should I start using it back again. Though that bulge appeared after that heating issue.
Beside the hardware, safety would be my bigger concern. Perhaps because I have heard few incidents with mobile phones where battery generated heat and caused some defect in bodies and continued use resulted in a blast in battery causing physical harm.
So if its advised to try it by charging 100% and monitoring backup time or any other advise.

Very strange behaviour of mouse, trackpad and finder

As if there were a demon in my Mac:
- left mouse click doesn't work correctly
- left mouse click clicks by itself
- cursor sticks to objects on the screen and drags them around, from desktop, from safari, anything
- dock doesn't appear
- when I drag the cursor over objects it marks them without me clicking left mouse click, it also creates rectangles
- click another window, but it doesn't come in foreground
- when all these strange things happen, the mouse pad seems not to work, it doesn't click, it feels differently, doesn't make the usual clicking sound, doesn't move down
- the USB mouse is no better, though! (when all this happens)
... I can end this ghost in the machine only by forcing the Mac to shut down
... after that it sometimes works ok for a while... then IT happens again
... closing and opening the mbp helps sometimes
is it the software, is it the hardware, is it both?
(I repaired disk permissions, cleaned PR ram, scanned for viruses)
any ghostbusters around???
p.s.: all these thing do not happen when I boot from my windows partition on the same mac

There are several possible causes for this issue. Take each of the following steps that you haven't already tried until it's resolved. Some may not be applicable.
1. Follow the instructions in this support article, and also this one, if applicable.
2. Open the Bluetooth preference pane in System Preferences and check for unknown or forgotten input devices. Disconnect any USB input devices that you aren't using.
3. Boot in safe mode and test, preferably without launching any third-party applications. If you don't have the problem in safe mode, but it comes back when you reboot as usual, stop here and post your results. If you can't boot in safe mode, do the same. If you booted in safe mode and there was no change, go on to the next step.
4. Reset the System Management Controller.
5. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
6. A swollen battery in a MacBook Pro or Air can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced without delay.
7. Press down all four corners of the trackpad at once and release. If there's any effect, it's likely to be temporary, and the unit needs to be serviced or replaced.
8. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built-in trackpad of a MacBook to behave erratically. If you're using such an adapter, disconnect it and test.
9. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
10. If none of the above applies, or if you have another reason to think that your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.
11. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.

Very strange behaviour of table values and event case

Hi all
i'm becoming crazy on my .vi
i want to change the second col values on click from yes to no and from no to yes simply by a click.
The problem is that this changing happens after some clicks on an old position.
Try to click on some "no" on the file that is attached.
Thanks a lot!

The issue took me a sec to understand but here it is. You are trying to change the value during the mouse up event. And you do... however you have just selected that cell in the table. So LabVIEW is waiting for the user to change the value, and in this case ignoring your change. All you need to do is add a property node to the end of that sequence that is Key Focus and set it to false

A very strange wired and wireless network issue

Hello,
I have never had any issue at all with my macbook (2008) until this week, I use it both for work and personal use.
Most of time, I'm used to be on customer site, so I use wired and wireless connections depending of the situation....
I have never had any issue at all with wifi neither ethernet connections during three years, until this week... and I can say this is the most strange thing I have ever seen....
Using wired or wireless connection, always the speed of network was really good, at home, many customers, etc never had any problem...
But this week I'm currently out of home, and the hotel where I'm staying I'm having very poor network rate....
Using wireless connection, the download speed is no more than 10kb.... and using ethernet I get less speed... but during the day I'm on customer site, using the ethernet connection and download speed is really good, more than 500k-800k....
I have already tried in the hotel few wifi connections (there are three) and differents wired connections (in diferent rooms) and the download speed is always the same, no more than 10kb...
During this afternoon, I could go into hotel's lab and could connect directly to the router using cable, same speed no more than 10kb....
The most strange thing is on their computers the download speed using wired connection is around 6Mb....
how is possible I'm getting no more than 10kb of download speed when the pc's at hotel using same wired connection gets 6Mb?
I have already deleted current network connections, execute onyx to clear everything, perform dhcp connection, tried manual ip etc, and always the results are the same...
I know there is no problem with the macbook, because it works pretty good at every location I've been... but until this week...
Sincerely I'm getting a little crazy here, I'll appreciate any help!!!
thanks in advance

I've seen something like this on my T400 when it was running Vista. Now that I use Win 7 it's been OK. I rather doubt that your issue is the same but I'm tossing it out here just on the off chance.
Im my case, I had to downgrade my Intel 5300 card to a 5100 (as suggested by a Lenovo 2nd-tier tech) to get things working.
My symptoms were a little different. Wifi was fine until I went back to a wired network. After that, trying to use the same wifi AP as before would end up associated, but no internet access. DHCP wasn't working. The GUI "find" app didn't work as expected either. Some APs showed up, and some didn't.
If I configured for automatic connection to my home AP it would try and fail. Just rebooting at that point would again attempt an automatic connection that would succeed.
What I have noticed now that I run Win 7 is that Access Connections is completely useless. Often the "finder" doesn't show an AP 3 feet away. I didn't notice that this happened after a switch from wired, but maybe.
Are you using Access Connections? If so, you might try uninstalling it.
Sorry I can't be of real help,
Z.

Strange lines and dots with Radeon 1900XT

I have a strange problem with the output from my video card.
My setup is a Mac Pro 2.66 with a Ati Radeon 1900XT card and two 20" cinema displays.
Sometimes, and for some reason often with dark grey tints or black the videocard renders a single pixel (red, green, magenta as far as I have seen). At first I thought it was a stuck pixel in my display but when I drag the problematic window the pixel moves too (I can also screencap it). If I move the window slowly I see a trail of pixels appearing. I also get lines (not full screen width) with sites as youtube over the video (but wider than the video). Anyone familiar with this, or suggestions? Can't tell if it is a hardware or software failure, after reboot it doesn't appear for a few days.
cheers Trepn

Having just discovered this thread and having very similar symptoms to everyone else, (lines appearing etc - pic here - http://theappleofmyi.com/blog/?p=1301, I updated the firmware on the X1900 Xt, which did nothing to help....
Then out came the card and I used a rocket blower to remove a HUGE amount of congealed dust from the fins and as I type this, it seems to have solved the problem!
So, I urge you all to follow the advice given by a few people, and clean your card out!

Strange Behaviour of MII with Datediff built in function in BLS

Hi,
Here's one strange thing happening with MII 11.5 when using datediff built-in function in BLS
I will create a Local Variable called Dur of type Double.
and then Assign datediff(startdate,enddate)/3600 value to Dur Variable
where startdate = 05/01/2009 07:00:00 and enddate = 05/03/2009 07:00:00
both start and end dates are in proper xml formats.
When I evalute this expression I get a value of 48 hrs which is right but when I assign the same thing
to Dur variable and when I check value of Dur in Tracer it shows me as 47 hrs.
This is true for all the datediff values greater than 28 hours till 28 hrs I get exact results but after 28 hours I see this pattern where I get output = (Actual hrs - 1)
Please note I checked the same thing in MII 12 but not found any such strange issues.
Any thoughts on this odd behaviour .........
Regards,
Adarsh S P

Hi Daina,
First thanks a lot for help, I need bit more assistance..
I found Service Pack 5 and Service Pack 6 from Archive folder.
But our SAP MII version says 11.5.3 b66 so here are couple of things I would like know
1) I believe we are running on SP 03. is my understanding right?
2) If yes then can we install directly the SP 06 on top of SP 03?
3) If No then do we need to first install SP 04, then SP 05 and then SP 06?
4) where will I find SP 04?
Regards,
Adarsh

Very Strange error and can't find any answer anywhere in the net

I created a login form (see below).
If I use the regular HTML form and form fields for the username, password and submit button I don't get any problem viewing my form
But if I use cfform and cfinput form fields I get this error.
Here is my cfform codes:
cfform name="login" action="/login/checkLogin.cfm" method="post">
cfinput type="text" name="username" size="25" required="Yes" message="Please enter your username">
cfinput type="password" name="password" size="25" required="Yes" message="Please enter you password">
   cfinput type="submit" value="Sign In">
/cfform>
When I launch this page I get this error and I don't understand what this means and what am I supposed to do, please help!

Using cfform
To start with, leave cfform aside. You will find in the documentation that most developers are abandoning Coldfusion's native UI tags, for example, cfform, cfgrid, and so on. They are outdated and occasionally perform erratically. If you wish to validate forms, use a Javascript library such as jQuery.
Implementing Site-Wide Error Handler
By default, there is no site-wide error handler configured. It is advisable to create your own. Then register the path of the page in the Coldfusion Administrator.
As the name implies, it is a CFM page which ColdFusion runs when it encounters an error on your site. Creating your own enables you to present a simple, customized, user-friendly page to your visitors.
Alternatively, you may choose to implement a Secure Profile. This is available in the Administrator, on the page Security => Secure Profile.
When you check the box, you configure Coldfusion to automatically implement all the security measures listed in the table. That includes Coldfusion's own the Site-Wide Error Handler. It is the system file, /CFIDE/administrator/templates/secure_profile_error.cfm.

Very strange behaviour (Image Squished) every time I export

I have a strange issue happening.
On one of my mobile pages if I export my HTML the image appears squished. However if I make any adjustment to the image in Muse prior to exporting. i.e./ Shift its X or Y property, etc and then export again .. it appears correctly. If I then export again without touching it .. its back to being squished again. It's really annoying and tedious right now that every time I export HTML for my site I have to go to the mobile layout and make an adjustment to that single image to ensure it's not going to be squished.
Any ideas ?

This is driving e nuts.. I have to manually do this every time I export my HTML. .. why is this happening ? Why only with 1 image too ?
