Insert row with datapages/bc4j problem with primary key

Hi everybody,
i tryed to insert a new row into a table with primary key (id) and therfore used a datapage, where there is a html-form and the data tag set attribute to get the data into the BC.
I also want to use a sequence for the primary key and made a trigger to insert the key-value before insert. but in this case it doesnt work. I also tryed to get the sequence to the BC -Layer (so that i can set the PK in the View OBJ already) with a View Object but I dont know how.
so what schould i do??
thanxx

There's a know issue, when creating a record with blob, the blob content won't show until committing. The blob is added too late, which means you're in trouble with not-null fields...
Sue, is this logged as a bug? And the dialog captions?

Problems whit primary key = '#'

Hello!
I've got a problem with an application based In Forms of a Table with Report when the table primary key has the value '#'.
From the report, when I press the 'update' button, this value is contained in the URL link with de upddate form, but all the fields in the form appear empty, so I can't update or delete this row.
form URL example https://servername/f?p=133:10:3953379412098904::NO::P10_ID_TRAMO_FACTURACION:#

Hi,
character # has special meaning when used in URL - http:/server/some.htm#text means "load page some.htm and jump to place where construction <a name="text"> was placed". If there's nothing after #, browser won't jump anywhere... But # character is lost anyway.
Solution? You can escape this character and instead of # use %23 - http://server/apex/f?p=100:1:85284257448058::::P1_X:%23

UIX BC4J Problem with primary key

Hello
I use Business Components (Entity and Views) and the backend is a postgresql; it works with BC4J-JSP perfectly;
i switched to use uix; but have strange problem:
I have defined in the entity a create-Method to set the primary key of the current row to a defined value. If i test
it in the component browser it works all; but when i switch to my application, i receive allways a "1" in the rendered field which should have the current primary key.
Just to see if it works with Oracle right i tested also against Oracle 8.1.7! It works as it should.
Has anybody an idea how i can solve the problem.

Marcel,
I cannot reproduce this in version 10.1.2.2. We did not "fix" this, although changes in the runtime might have fixed this "silently". I suggest you upgrade to 10.1.2.2 and see whether you still get the error.

Need to create form on a table with report with a table has NO primary key

Hi, I tried to created some insert/update/delete form+report in an application, it works fine only if the table has primary key. Does anyone know how to create the same functionality with a table with no primary key? I saw an application is built on older version of htmldb that is using tables with no primary keys at all.
Here are the specific issues that I am facing:
- I am building some Form on a table with Report, it requires the table with primary key for form to update. Is there a workaround that I can use tables that has no primary keys at all?
- Say if primary key is necessary in the previous report+form, but the maximum number of columns that I can use to composed a primary is only 2 for that Form-Report, I cannot find anything handling > 2 primary key. Do you know if there are some ways to composite a primary key from many columns together?
Your help is really appreciated.
Thanks,
Angela

Sorry to ask response so late. I had no time to get back to that issue before.
Regarding the triggers, I can make it work for the update, but not the insert.
Here is my trigger:
create or replace trigger STATUS_T1
instead of insert on STATUS
begin
insert into STATUS ("LABEL", "AREA", "OWNER", "TEST_NAME", "STATUS", "REMARKS", "BUGS", "DEV_MGR", "TEST_BY_DATE")
values(:new.LABEL, :new.AREA, :new.OWNER, :new.TEST_NAME, :new.STATUS, :new.REMARKS, :new.BUGS, :new.DEV_MGR, :new.TEST_BY_DATE);
end;
by any chance, you can notify what is wrong?
I already skip the ROWID when inserting to the view STATUS, but I cannot figure out what is wrong when inserting a new record to that view.
It gave me the following errors:
ORA-06550: line 1, column 38: PL/SQL: ORA-00904: "ID": invalid identifier ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
Error Unable to process row of table STATUS
Then, I turned to debug mode, I am thinking that maybe because I use a HIDDEN item to hold the value of ROW_ID as I use the rowid (called ID in the view) to retrieve the record as a column link from previous page. What do you think?
Thanks again,
Angela

Error with Links if using x3 primary keys

Hi Folks:
Here is the error code I'm receiving:
ORA-01422: exact fetch returns more than requested number of rows
Unable to fetch row.
Background: I am using Application Express 3.2
All of the pages I have created that rely on x2 primary keys (first_name, last_name) work fine.
I have a table that has x3 primary keys: Table is called "time_off_awards". The x3 primary keys are: last_name, first_name, approval_date.
I created a report that works properly and lists the awards for each person (each person can receive more than one award-on different dates).
I also created an edit link that works properly IF *(only if)* each individual has only one award. If the individual has more than one award then I get the error above. When I set up the link I used all three keys. The x3 PK's should uniquely identify each row, but if the same last name/first name appear more than once (that is if the person has more than one award) I get the error. I thought at first maybe it was just not reading the 3rd key/part of the link (approval_date), but it shows properly if you move your cursor over the edit link.
Here is a link to a screen pic of how I have my link set in Apex:
[http://www.wczone.com/link_settings.gif]
Here is a link to a pic of the report with some info:
[http://www.wczone.com/report_link.gif]
If needed, here is my table info:
CREATE TABLE PERSONNEL.TIME_OFF_AWARDS (
LAST_NAME VARCHAR2(40) NOT NULL,
FIRST_NAME VARCHAR2(25) NOT NULL,
APPROVAL_DATE DATE NOT NULL,
HOURS_OFF NUMBER(3),
CITATION VARCHAR2(1500),
/* Keys */
PRIMARY KEY (LAST_NAME, FIRST_NAME, APPROVAL_DATE),
/* Foreign keys */
CONSTRAINT TOA_PERSONNEL
FOREIGN KEY (LAST_NAME, FIRST_NAME)
REFERENCES PERSONNEL.MARC_PERSONNEL(LAST_NAME, FIRST_NAME)
TABLESPACE PERSONNEL;
Thanks for any help, I've tried looking at a couple of Apex books, but they didn't help much.

Thank you everyone for the help and information you gave to me.
Your ideas and advice helped me to think through the issues involved.
The way i actually found to work around this issue was a little different.
What I did was the following (which may only be usable with empty tables. If its possible to create a new column with a sequence and trigger on a table that already contains data it should work also):
1. I removed the current PK's that were currently set.
2. I added a single, unique PK (that used a sequence and trigger to automatically increment) to the table as was suggested in this thread and other APEX forum threads.
3. I changed the link on the report so that it used the new PK, and also changed the PK used on the forms (under Processes - both the page rendering and page processing processes).
The Difference:
4. Next I changed the table (not by using APEX, but directly) from using the automatically generated ID as the PK, back to using the compound PK (x3 keys). I then added an constraint to make sure that the automatically generated column was unique. So now I have the compound PK that my supervisor wants us to use, and I'm able to use a unique, automatically generated key for APEX to use.
I found also that if you already have a column that uses a unique/auto-generated key you can still use it with APEX without switching keys around.
1. I added the new column to the sql in the reports source section so that the new column was searched (and then used 'hidden' so it wouldn't be displayed on the report users would see).
2. You can still add the unique key under the processes on the form that is being linked too under the Primary key tabs. If its not a PK it won't show up in the pop up which is to the right of "Item Containing Primary Key Column Value" but it can be entered manually (i.e. p23_AUTO_ID) and it will work fine. You would also need to edit your form so that the auto ID that is being passed from the report is part of the form - but hidden if desired).

Ipad 2 with IOS 6 problems with apps and battery

Ok, I had updated my iPad the day of or day after the IOS 6 came out and at first I had no problems with it. Except now, for some reason I am starting to have problems with different apps and with the battery life. First off within 15 minutes, it went down to almost 90% charge with it being a full charge and me hardly using any apps and closing the ones I wasn't using (which was just safari and Facebook open). But the problem I have been having is that I cannot chat with my friends on the Facebook app now because it will show its loading the chat box and then freeze up. With pages and numbers, they seem to take longer than usual to load up which is around 10 seconds or so before I can do anything. I had uninstalled and reinstalled the apps with no effect and tried restarting my iPad. It also seems like my iPad is taking longer to shut down and turn on than usual even though i make sure all the apps are closed before turning it off. (the location services, bluetooth, notifications, FaceTime, messages, and limit ad tracking is all turned off to help with battery life and i don't use them.)Is there any suggestions on what I can do to fix this problem?

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Windows 7 Home Premium with 802.1x problems with the Authentication

We have problems with OS Windows 7 Home Premium 802.1x, the message in ACS:
EAP-TLS or PEAP authentication failed during SSL handshake

Problems with purchased items, Problems with purchased items

I have problems with my purchased itens displayed in iPhone.
When I access "iTunes > Purchased" (on iPhone) it does not show one of the albums that I purchased. When i acess "Purchased items" in iTunes (MacBook) this album is showed.
because of this I purchased two times the same album.
How to solve this?

I just called the 1-800-My-Apple and the said there is really nothing they can do about it. They said I had an outstanding payment of $8.54 (or something like that), I said I know b/c of the problem I am having with my bank, but NO previous completed purchases should have anything to do with this outstanding payment . It should not keep me from being able to update or download previously completely paid apps, TV Shows, or movies - they are mine, and I paid for them. I submitted a complaint.. that just isn't right!

WS2012 Standard R2 with Essentials sudden problem with Server Manager, Essential Dashboard and other services

Hi all,
I have a problem with my Windows Server 2012 R2 with Essential installed. When I try to run Server Manager the server manager window doesn't appear and the same thing applies for starting the essentials dashboard. This leads to that some of the features doesn't
work properly like remote web access, client backup and so on. When I check the Services a lot of services haven't even started. Trying to manually start for example Windows Server Essentials Management Services gives me following error message:
"Windows could not start the Windows Server Essentials Management Services on Local Computer. Error 1068: The dependency service or group failed to start"
What can be wrong here? I haven't done anything to the server that could start these problems. This started all of a sudden.
Thank you all in advance for any help.
EDIT:
I rebooted my server in safe mode and I tried to run SFC /Scannow which stops at 84% and gives me following message:
"Windows Resource Protection could not perform the requested operation."
I also tried to run "DISM.exe /Online /Cleanup-Image /RestoreHealth". This did not help either. It completes the operation but nothing changes. The problem is still there.
I thought that my server backups were OK and that this problem would be gone by restoring the C: drive with backup image. The problem is that all my good backups was rewritten with new backups that could not take backup of the C: drive for some reason. Now
I need to solve this problem without reinstalling the whole operating system.
EDIT:
I have also completed the chkdsk C: /r command and now the SFC /Scannow command can be completed, with notification that some files could not be fixed. I have attached the sfcdetail.txt file which points out that
"tsgclean.exe" cannot be repaired. What has that file to do with my WS2012 problems...
2015-01-04 03:12:54, Info CSI 00000477 [SR] Cannot repair member file [l:24{12}]"tsgclean.exe" of Microsoft-Windows-TSProxy-EdgeAdapter,

Hi,
Did you remember any operation which you had done before this issue occurred? For examples, install any update,
install any third-party application or any other? Just a confirmation, thanks for your understanding.
For those problematic services, please open services’ Properties and navigate to
Dependencies tab, then check if all system components which this service depends on run as normal.
In addition, please open Event Viewer and check if find relevant events. Meanwhile, please follow the path:
%programdata%\Microsoft\Windows Server\Logs and check Dashboard log file if find more clues.
By the way, when you run
sfc /scannow command completely, did you open Server Manager or Dashboard again? Any difference?
If any update, please feel free to let me know.
Hope this helps.
Best regards,
Justin Gu
Please remember to mark the replies as answers if they help and unmark them if they provide no help. If you have feedback for TechNet Support, contact [email protected].
Hello Justin,
Regarding the third-party applications:
I have not installed any third-party application that could cause this problem. All my third-party applications that are installed on the WS2012 R2 are confirmed working well with the operative system and are installed at the time when I hadn't these problems.
I cannot say anything about windows update because that is something that I update once in a week after checking that no user is reporting any issues. I have learned my leason with windows update when I had Surface Pro 2, that was a dissaster.
Regarding the Windows Updates:
Anyway, I tried to remove all the windows updates before as well (not the security updates) down to 5th December which is the time when I know that my server worked well. Only two updates could not be removed (KB3012199 and KB2989647). I don't
know if these two updates can cause any problem?
Regarding the problematic services:
For example: Checking the properties for "Windows Server Essentials Management Service" -> It is dependable on
"1. Active Directory Domain Services" and "2. Windows Server Essentials Provider Registry Service".
No 1 is running but not no 2. If I try to start no 2 service it will give me the same message as before:
"Windows could not start the Windows Server Essentials Management Services on Local Computer. Error 1068: The dependency service or group failed to start"
Regarding the Logs:
I have uploaded Dashboard log files which are created after 5th December to my dropbox account: Link
Regarding the SFC command:
Of course, when the SFC command was completed but with error that it could not repair
tsgclean.exe I tried to start the essentials dashboard and WS2012 server manager with no luck.
What about the error message? I looked up that file in the explorer and it is located in folder "C:\Windows\WinSxS\amd64_microsoft-windows-tsproxy-edgeadapter_31bf3856ad364e35_6.3.9600.16384_none_2ec8d374a0ac5606"
Why can't it be repaired and what kind of file is that?
Best regards

DW CS4 with Windows 7 - problems with Extension Manager

Hi
I am new to this forum and have searched to see if anybody else has had this issue but can't find it.
I have recently installed CS4 on a Windows 7 laptop. I had originally downloaded and installed it on an XP laptop where it was all fine.
I had some problems with installation with the unlocking of the serial number on the new laptop - this was resolved by Adobe support.
However now I am trying to install extensions and get the message that the Extension Manager is unavailable and I have to re-install.
I have tried to contact Adobe using the Support portal but my post has been there for 4 days and I have had no response. I have just tried to call and after 12 minutes of being on hold - when the wait time was supposed to be 1 minute - I gave up.
Can anyone help with this. Does this mean an uninstall then re-install again? In which case I will have the same serial number issue that I had before. Or is there any other way I can install the Extension Manager?
Would really appreciate any help.

I had a somewhat similar experience with the 4.2.1 upgrade with my computer. With my Q6600 running at 3.2 GHz, Vista x64 and with PPro CS4/4.1 update, I ran the PPBM4 benchmark and scored an 83.8. I then installed Win 7 x64, clean install etc… and re-ran the PPBM4 benchmark, with the same 4.1 update and with all system configurations the same as before, my score improved to 68.8, fantastic! I was very impressed with Win 7 x64.
This was short-lived because I updated PPro from 4.1 to 4.2.1, re-ran the PPBM4 benchmark and my score fell to 83.1 seconds, not impressed with the 4.2.1 update as far as this benchmark was concerned. I replaced the Q6600 with a Q9450, also over clocked to 3.2 GHz and with Win 7 x64, ran the PPBM4 benchmark and scored a 68.1; I got back everything I had lost in system speed from the 4.2.1 update plus some.
The Q6600 does not have the SSE4 instruction set while the Q9450 does. Perhaps the 4.2.1 update benefited CPU’s with SSE4 while those CPU’s without it, took a performance hit, just a guess.

JSF with JavaScript ! Problem with OnLoad()

Hello,
I have a .js (javascript) file which has one function. I want to call this function in my jsf-jsp page form.

Problem in primary key column where user does typo error.

Hi all,
I have a primary key in the table that some part of it was the current date. For example if today date is 3rd May then it will contain xxxxxx-0503 (where xxxxxx will be unique for this day). In order save time needed to enter the data, I achieve this by having another (non database) item in the datablock where the user type the xxxxxx part and use a pre-insert trigger to add the '-0503' part to the actual primary key item in the datablock.
This works well if the user enter the xxxxxx part in the non database item correctly. But the problem show up when the users have typo error in the non database item that break the uniqueness of the primary key. Form as usual will tell us that it cannot insert the item but when I try to fix the error, it will report that records has been inserted before. The only solution is to clear form and retype the xxxxxx part.
Anyone have any idea on what is the best method to implement this in form? Thanks in advance for your help.

Marcel,
I cannot reproduce this in version 10.1.2.2. We did not "fix" this, although changes in the runtime might have fixed this "silently". I suggest you upgrade to 10.1.2.2 and see whether you still get the error.
