Removing error

How to remove the error "Cannot invoke method multiply() on null object" while running the createInsert button in JDeveloper and ADF?

Well, when I click on my CreateInsert button, I don't see that error, so it appears the error is in something you coded.
Tell us some more information:
1). What version ADF/JDev?
2). Integrated WLS or standalone (and if standalone, confirm you've installed the ADR and extended the domain with JRF)
3). Tell us about the EO/VO (I assume you're using ADF BC) and any code you've written (including Groovy code)

Device removal error..... The card reader ejects itself

Hello, I'm new to macs and purchased a Mac Mini a week ago. Things were going well until I needed to move pictures from a digital camera to my mac.
I purchased a GE 19 in 1 card reader which is built for mac os x. I hook it up to a usb port and try and look at some pictures. After a few seconds, the card reader ejects itself and I get the "device removal" error. The error will then continue to appear over and over again. When I try to eject the reader using by clicking eject, the reader ejects and only reappears a minute later and ejects itself again. I've tried using another usb port and I know for sure that its not the cable.
If I can't get any prompt answer here, I'm going to call the Genius bar tomorrow morning and ask about the problem. <Edited by Moderator>

More often than not, when a card reader or other similar device disconnects from the USB bus because it is drawing too much power. In a card reader, that would not unusually be triggered not by the card reader itself, but by the insertion of a card causing it to read the content and mount the volume on the Mac's desktop. Part of the problem is that while everything is invariably quoted as USB compatible, many such devices don't entirely comply with the USB standard, resulting in conflicts or load demands which may be borderline, or worse.
You may be able to get more reliable performance from your reader by disconnecting other USB devices when you are trying to use it, or by using it with a powered USB hub. Occasionally, borderline problems can be temporarily resolved by connecting the device to a different port, if necessary switching devices around. Alternatively, it may be that in an attempt to produce a device with the greatest flexibility in terms of media compatibility, they have compromised on components.
I would generally recommend a card reader designed for the specific card type you need. These are typically far more reliable. If you need to use different types of card media, then be prepared to spent on a well established brand with a reputation in this sector of the market, such as SanDisk.

Device removal error?

I picked up a new 500 gig Hitachi hard drive to put into a vantex hd enclosure. Now every time I try and use it, i get a device removal error and the hard drive icon on the desktop disappears. I can't use Time machine or verify my hard drive in disk utilities because it always seems to eject itself. I tried a couple different USB cables and tried rebooting my computer. Both products are new, I'm wondering if it is a hardware problem and if it is, which one, the enclosure or the hard drive?
Any suggestions?

Thanks for the suggestion but..
Tried that this morning and it still doesn't work:( I turn it on, start up Time Machine and it starts backing up the files and then some times it will start backing up 20-30 gigs and then give me the device removal error, or sometimes it only backs up 10-20 mb before giving me that error, but even after it ejects itself the hard drive is still on, but i have to turn it off and then back on again for the disk to remount. I'm leaning towards a hardware problem, just not sure if its hard drive or enclosure. I bought both online and having to send them back is always a pain because they usually just send them back saying they work and tack on another fee. Im hoping to resolve this some other way, but running out of ideas.
Any other thoughts?

Remove Errors in list

I made a formula that returns a list, each list item is text type.
My problem is, i want to know if there are items that is a number, then I do this:
List.Transform([My List], try Number.From otherwise null)
The 'try <> otherwise <>' is not working, it not returns null, it returns a error, but that's ok, if returns an error is because is not a number. Then my problem starts... I tried everything to remove errors inside the list or chance them to
"null" but nothing works.
Any idea??

You need to write that in the form of a function:
List.Transform(list, (value) => try Number.From(value) otherwise null)
or using the "each" shorthand,
List.Transform(list, each try Number.From(_) otherwise null)

When waking from sleep getting "Device Removal" error on Lacie external

When waking from sleep getting "Device Removal" error on Lacie external drive. This drive is my Time Machine back-up and I don't want to lose it. I don't know if anyone else has seen this error. Let me know.

Getting this same error since switching from Firewire to USB. I have a Maxtor drive in an Adaptec enclosure. It has it's own power supply and both USB and Firewire 400 connections. Just upgraded to a new Mini from old Powerbook, so no more Firewire 400!
The big difference between USB and FW:
With the old PB G4 and Firewire, when I put it to sleep, I could hear the external drive actually spin down. On wake up, It would spin up and mount properly. Now with the Mini and USB, when I sleep the Mini, the external drive NEVER SPINS DOWN. I did some research and found that many drives have built-in power management that basically powers them down after some idle time. So the Mini is going to sleep with mounted drives, at some point later the drive sleeps itself, then when the Mini wakes, the drive's not there.
Obviously, Firewire is doing a better job of talking to my external than USB. I'm ordering a FW400-to-800 cable and will test this. I also think it has something to do with the chipset/firmware in the external enclosure, as many people are reporting their external USBs behave properly during sleep.

Firewire drive Device Removal error

I have three (3) firewire enclosures and only one of them works with my intel Mac. All three work great with my old G4 laptop and iMac but now I connect them to this new intel Mac and I get the beach ball that spins and can not read the drive. Well actually I can read the drive for maybe a minute before it locks up and in some cases it dismounts by itself and give me a Device Removal error. I have tried them one at a time and only one of the enclosures seams to work without any issues, the other two will work fine on the G4 but not on the intel. One of the enclosures that I have trouble with I formatted the hard drive using the intel Mac with Disk Utility and still no luck. Could this be a driver issue with the intel Mac? I know it's not the hard drive because I swap it into the other enclosure and it works fine. So what gives? Any suggestions would be helpful. Rick
Mac Pro Mac OS X (10.4.8)

Took your advise and called Apple support concerning this issue. Apple support person was not surprised by the front port causing some issues when transferring large amounts of data. Even though the rear ports could handle this with no problems. He reported that the front ports are similar to a hub and are there for convenience for small transfers and are not hard wired into the motherboard like the rear ports. He suggested that for large file transfers should always use the rear ports or a powered hub such as on the back of the Mac HD Monitor. So there you go... not what I was looking for in a answer but makes sense. Hope this will help others not waste a lot of time wondering why some issues pop up when using the front ports. Rick

Device Removal Error Notification

I accidentally stepped on the USB cable of my external hard drive and my computer showed a device removal error notification and that data might have been lost. I know properly ejecting the hard drive clears out the cache, but how can you tell what data was lost. Is it obvious like an entire folder/file would be missing, or would just pieces of data from a file be missing?
Also, it said data MIGHT have been lost or damaged. Is it possible that nothing happened at all?

It could potentially damage multiple files, but I would consider it unlikely. More likely it would damage the disk directory, affecting the entire drive, rather than damage more than the file being written. Again, though, I won't say it's impossible.
I've also tried to run Disk Utility on it to verify the disk, but it says the disk could not be unmounted
Got any software accessing the drive, such as iTunes, iPhoto, or anything else that might have a file open on the drive?
As to your query, what you're seeing seems normal. It's telling you how many files it sees (and "files" do not necessarily equal "documents"; it's what a computer considers to be a file, which can include all sorts of invisible items). As to what "clusters" are, there's a good explanation here:

Device removal error when flash drive is plugged in

I have a 1GB flash drive that I have used for a while with my Windows XP desktop. I switched from a PC laptop to a Mac Book Pro running Leopard. But the Mac Book gave me the drive removal error when I tried to use the flash drive. The PC desktop worked with the drive just fine. So I backed up the flash drive and reformatted it in FAT32. Then I reloaded the files. For a short while I had no problem with the Mac Book. Now I am getting removal errors again. I have been careful not the remove the drive, either from the PC or or the Mac Book, without going through proper procedures. It does no good to "repair" the drive from the Mac Book. Any suggestions?

DTW: error "Duplicate bin locations have been removed - error id 1470000307"

Hi,
When attempting to import inventory data, using the DTW business object "Inventory Transfer" and using the templates "Transfer", "TransferLines", "StockTransferLinesBinAllocations", "BatcheNumbers" and "SerialNumbers", the following error message appears:
"Duplicate bin locations have been removed - error id 1470000307"
Prior to attempting this import, I had successfully imported the Bin Locations and the Warehouse Sub Level Codes through DTW.
This task relates to the replacement of the Inventory Pro Addon by the Bin Location functionality of SAP B1 version 9 PL10.
Any advice would be greatly appreciated.
Kind Regards,
Erik

Hi,
Please refer SAP note, It may be related to your issue:
1906789 - Unable to import bin location allocation information in
stock transfers
1964346 - DTW_Templates for Inventory Transfer with Bin Allocation
do not exist

How do you remove error 0X00000709 from your computer? I just removed one printer and added another!

     I have a HP Pavilion Elite HPE computer and had an HP 6500 printer as my default. I purchased a LaserJet Pro CM1415 and loaded it into my computer and removed (I thought) was the software for the HP 6500.
     However when I try to make the CM1415 my default it gives me an error 0X00000709 and tells me I can not do it. I no longer have any other printer listed, however I noticed some programs (Adobe for instance) don't even recognize the new printer, just the 6500 which got removed. I have already removed the drivers (software) for the new printer and reloaded it. Also I checked the registry and the 6500 is listed there. I did nothing with the registry at this time.
     I would like to know how I can remove this error and make my new printer the default (only one listed) one? Thanks in advance for any and all answers

Hello Porgeman,

How to remove error from propagation and verify replication is ok?

Have a one-way schema level streams setup and the target DB is 3-node RAC (named PDAMLPR1). I run a large insert at source DB (35million rows). After committing on source, I made a failure test on the target DB by shutting down the entire database. The streams seems stopped as the heartbeat table sequence (it inserts a row each min) on target is still reflecting last night. We get the error in the dba_propagation:
ORA-02068: following severe error from PDAMLPR1
ORA-01033: ORACLE initialization or shutdown in progress
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 1087
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 7639
ORA-06512: at "SYS.DBMS_AQADM", line 631
ORA-06512: at line 1
08-FEB-10
while capture, propagation, and apply are all in enabled status. I restarted capture and propagation at source DB. But still see the error message above. My questions are:
1. How to delete the error from dba_propagation?
2. How to verify the streams is still running fine?
In normal test, during such large insert, the heartbeat table added a row in an hour. Very slow.
thanks for advice.

Well, if I can give you my point of view: I think that 35 millions LCR is totally unreasonnable. Did you really post a huge insert of 35 millions then committed that single utterly huge transaction? Don't be surprised it's going to work very very hard for a while!
With a default setup, Oracle recommends to commit every 1000 LCR (row change).
There are ways to tune Streams for large transaction but I have not done so personnaly. Look on Metalink, you will find information about that (mostly documents id 335516.1, 365648.1 and 730036.1).
One more thing: you mentionned about a failure test. Your target database is RAC. Did you read about queue ownership? queue_to_queue propagation? You might have an issue related to that.
How did you setup your environment? Did you give enough streams_pool_size? You can watch V$STREAMS_POOL_ADVICE to check what Oracle think is good for your workload.
If you want to skip the transaction, you can remove the table rule or use the IGNORETRANSACTION apply parameter.
Hope it helps
Regards,
