Validation and Read Only Problem

Hello there,
I have this problem. I have an item that I need to hide when the page runs, and this item needs to have a validation.
So my question will be. How can I bypass the validation if the item is on read only?
Any ideas?
Regards

I have done something like that , but there was some criteria to determine who can see what. For example , if you have some hidden or global item that sets the ROLE of the user ( ex. ADMIN see both items , BASIC sees only one item ) then you can combine that in your validation condition. create two version of the validation as follows:
1- check if both items are not null
Condition: ROLE = ADMIN ( or whatever you use to dermine who can see both items )
2- check if only the first item is not null
Condition: ROLE = BASIC( or whatever you use to dermine who can see only one item )
Hope this helps,
Sam

Crashes and read-only file systems

Notice: I apolgize for the long post, I've tried to be as thorough as possible. I have searched everywhere for possible solutions, but things I've found end up being temporary workarounds or don't apply to my situation. Any help, even as simple as, "have you checked out XYZ log, it's hidden here", would be greatly appreciated. Thanks
I'm not sure what exactly caused the issues below, but they did start to happen within a day of running pacman -Syu. I hadn't run that since I first installed Arch on December 2nd of this year.
Setup:
Thinkpad 2436CTO
UEFI/GPT
SSD drive
Partitions: UEFISYS, Boot, LVM
The LVM is encrypted and is broken up as: /root, /var, /usr, /tmp, /home
All LVM file systems are EXT4 (used to have /var and /tmp as ReiserFS)
The first sign that something was wrong was gnome freezing. Gnome would then crash and I'd get booted back to the shell with all filesystems mounted as read-only. I started having the same issues as this OP:
https://bbs.archlinux.org/viewtopic.php?id=150704
At the time, I had /var and /tmp as ReiserFS, and would also get reiserfs_read_locked_inode errors.
When shutting down (even during non-crashed sessions) I would notice this during shutdown:
Failed unmounting /var
Failed unmounting /usr
Followed by a ton of these:
device-mapper: remove ioctl on <my LVM group> failed: Device or resource busy
Nother of these errors had ever appeared before.
After hours of looking for solutions (and not finding any that worked) I was convinced (without any proof) that my Reiser file systems were corrupt and so I reformatted my entire SSD and started anew - not the Arch way, I know I set all logical volumes as EXT4.
After started anew, I noticed
device-mapper: remove ioctl on LVM_SysGroup failed: Device or resource busy
was still showing up, even with just a stock Arch setup (maybe even when powering off via Arch install ISO, don't remember). After a lot of searching, I found that most people judged it a harmless error, so I ignored it and continued setting up Arch.
I set up Gnome and a basic LAMP server, and everything seemed to work for a couple of hours. Soon after, I got the same old issues back. The System-journald issue came back and per the workaround on https://bbs.archlinux.org/viewtopic.php?id=150704 and a couple other places, I rotated the journals and stopped journald from saving to storage. That seemed to stop THOSE errors from at least overwhelming the shell, but I would still get screen freezes, crashes, and read-only file systems.
I had to force the laptop to power off, since poweroff/reboot/halt commands weren't working (would get errors regarding the filesystems mounted as read-only).
I utilized all disk checking functions possible. From running the tests (SMART test included) that came as part of my laptop's BIOS to full blown fsck. All tests showed the drive was working fine, and Fsck would show everything was either clean, or
Clearing orphaned inode ## (uid=89, gid=89, mode=0100600, size=###
Free blocks count wrong (###, counted=###)
Which I would opt to fix. Nothing serious, though.
I could safely boot back into Arch and use the system fine until the system decides to freeze/crash and do the above all over again.
The sure way of recreating this for me is to run a cron job on a local site I'm developing. After a brief screen freeze (mouse still moveable but everything is otherwise unreponsive) I'll systemctl status mysqld.service and notice that mysqld went down.
It seems that it's at this point my file systems are mounted as read only, as trying to do virtually anything results in:
unable to open /var/db/sudo/...: Read-only file system
After some time, X/Gnome crashes and I get sent back to shell with
ERROR: file_stream_metrics.cc(37)
RecordFileError() err = 30 source = 1 record = 0
Server terminated successfully (0)
Closing log file.or_delegate.h(30)] sqlite erro1, errno 0: SQL logic error or missing database[1157:1179
rm: cannot remove '/tmp/serverauth.teuroEBhtl': Read-only file system
Before all this happened, I was using Arch just fine for a few weeks. I wiped the drives and started anew, and this still happens with just the minimal number of packages installed.
I've searched for solutions to each individual problem, but come across a hack that doesn't solve anything (like turning off storing logs for journal), or the solution doesn't apply to my case.
At this point, I'm so overwhelmed I'm not even sure where exactly to pick up figuring this issue out.
Thanks in advance for any help

Did this occur when you booted from the live/install media?
What is your current set up? That is, partitions, filesystems etc. I take it you have not yet reinstalled X but are in the default CLI following installation?
If turning off log storage didn't help, reenable it so that you may at least stand a chance of finding something useful.
What services, if any, are you running? What non-default daemons etc.?
Does it happen if you keep the machine off line?
Have you done pacman -Syu since installation and dealt with any *.pacnew files?

Can't mount USB disk with the atribute of fix and read-only

Hello All,
I have a usb disk which is set as fix(non-removalbe) and read-only. I tried to connect it to Macbook version 10.4.11 ,but it failed to mount the disk. However, connecting to 10.5.X and windows XP work fine. I am wondering is it a bug specifically in 10.4.11 only ? Could I get any patch for this problem ?
Thanks,
Ying

HI Ying and Welcome to Apple Discussions ...
Try repairing disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac.

Missing "illustrations" tab and read-only information

After a Windows XP Home repair, no illustration tab and read-only information by new music downloads. Have most recent itunes. Can someone help me...please?

Thanks Gilad, In that case, is there then a way (via a script) that if I leave field 2 as not readonly, so the cursor moves into this field on tab out of field one, that I can reject any input from the user, if field one does not contain any data ? I thought this might be a solution. I have the script with the If Else statement, that sets the value of field 2 to "", if the value of field 1 is also "", but what is the else statement required to accept the value, if the content of field 1 is not "" ?.
The script preoduces an error, if field 1 is blank, and I try to enter data into field 2 and then tab out of field.

Possible to make an item editable for certain users and read only for other

Is it possible to make an item editable for certain users and read only for others?
I've been able to accomplish this by taken the select statement that I used to define an authorization scheme, placing it in the Read Only condition of the item. However, I would like to simply reference the authorization scheme to utilize caching, and to help keep things cleaner for future maintenance.
Is it possible to reference an authorization scheme in an item condition similar to the way another item can be referenced by preceding it with a colon (i.e. :P1_First_Name)?

Thank you, your suggestion worked.
It would be nice on a future release of APEX if a drop-down box existed under the Ready Only section that would allow an existing Authorization Scheme to be selected or negated when applying the Read Only attribute to a form item.

Editable and Read-Only Date Picker have different display formats -- Bug?

Hi all,
This is a follow on to a previous posting about getting a Date Picker field to display read-only (Date Picker and Read-Only Condition works on LAST state of element
Now past that hurdle, I have noticed something about the date picker field when it is displays read-only. Namely, the date format is not the format selected, nor does the read-only date format comply with the format mask in the source section.
I've modified my small test app to work as intended in order to demonstrate this feature. I also opened it up so everyone can see it <blush>. You can find it here: http://htmldb.oracle.com/pls/otn/f?p=42513: Please navigate to the Update Project tab.
When a project in Program One through Four is selected (which has a Spec Committed date), the date is displayed DD-MON-YY format. When a project the other Programs (which do not have Spec Committed dates at the time of this writing) are selected, and a date value selected with the date picker, the date is displayed in the anticipated DD-MON-YYYY format.
Anyone else notice this, or have I just missed something obvious?
Thanks,
Petie

I'm not sure why this happens but to work around it I added this before header process code to the page:
execute immediate 'alter session set nls_date_format = ''DD-MON-YYYY''';

Problems with Conditional Display and Read Only

Hi Everybody,
I have a form to Add/ Modify Table Info.
I have column which stores numeric value (like no. of purchases, no.of returns etc.,) and I have a text field with this Database column as Source.
In some cases the value is a foreign key (Id of the Owner, Buyer etc.,) to another table. In such cases, I want to display a select list containing people information. Is that possible?
This is what I did to achieve that
I added a select list with info from second Table. Made both the text field and the select list to conditional display and conditional read only.
My understanding is that When an item is made read only it should not be saved to the Database.
But while Updating I am getting the following Error
ORA-06550: line 1, column 130: PL/SQL: ORA-00957: duplicate column name ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored.
Any can anybody help me out on this?
Thanks
Nimmi

My understanding is that When an item is made read only it should not be saved to the Database
No, all page items with a Source Type of "Database Column" will be used by the Automatic DML process to insert/update the database. Form inputs with the "disabled" HTML attribute set are not POSTed to the server.
Try to create 2 items, one Select List and other Text Field but setup their conditions such that only one of them is rendered on the page at any given time. That might work.

Field Validation on Read Only Field

I'm trying to create a pop up error box if a field contains null values. The problem is that the field I'm trying to do the validation on is a read-only field. It's the Account field on the Contact Object or Module. It won't allow me to include validation. The goal here is to have a POP UP ERROR box come up if someone does not select a value for that field. Making it required doesn't generate a popup box, it only has a small "required" text next to the field which can be easily missed by a user. Any ideas?

Hi !
I found the way to do what you wan't, but it sounds a bit strange for me...
You have to put a field validation on the Account Id field. I made some tests to know what is in the AccountId field when it's blank and i see that the value is "No Match Row Id" !!
So your validation rule must be simply
*<> "No Match Row Id"*
It worked for me, the error message appears... But I think this is something we have to report to Oracle...
Hope this will help, feel free to ask more !

Popup LOV and read only

Hi there,
I want to use a Popup LOV instead of a select list. The thing is with Popup, the user can manually fill the text field value. Is it possible to use a Popup and have a read only textfield, to make sure the user's entry will be valid ?

I try to fill disabled="disabled" into popup LOV of Tabular form element but don't work, the
behavior of text field is the same with or without this setting.
My version of oracle apex is 3.1.1.00.09 installed on an Oracle 9.2.0.6 database.

Issue regarding open word file and read only mode using c# & MS-word interop

i am programmatically open a word file for search and highlight keyword. my routine is working fine. the problem is when i am opening the file programmatically then a dialog come and ask me to open file in read only mode. the dialog look like below one
actually i do not want to open the file in read only mode because people can open and like to change and save. so guide me what i can do to not to open the file in read only mode.
here is my full code. just have a look and tell me what is wrong in my code or tell me any trick as a result i can open the file not in read only mode. here is my code.

                if (word != null)
                    System.Runtime.InteropServices.Marshal.ReleaseComObject(word);
                word = null;
                doc = null;
                GC.Collect();
                GC.WaitForPendingFinalizers();

I know it's a very old issue and I reached to this page looking for a solution. Finally, I have found a fix to this problem.
The problem is that we create an instance of Word and do not close it correctly. This makes program believe that the file is already open and hence you're getting the respective message of file being locked by you.
Set the visibility of your application to true and then when you close it both file and instance should close and you will not get the problem again.

Read-only problem

I'm completely new to jdeveloper (v 9.0.3.5) with the OA extension components. I'm having problems when I have copied the various xml & java class files from the server to my local PC, replicating the structure on the server. When I then add these into my project the BC come in as read-only, so do all the files within the BC. If I create a new BC, this is fine and fully editable. I am obviously missing a trick here. Can anyone shed any light on this?
Thanks Jeanette

Hi,
1. Select the project folder in the exporer and set the "Read-Only" proprty to false.
2. ReImport the Project once again.

Read-Only Problem during Boot

Hi,
I tried to update my system today, like every week, with the standard command pacman -Syu. After installing all updates, my window manager (gnome3) crashed and i tried to restart my System. After the grub window appeared and I choosed my kernel the normal startup commands are shown until the Arch prompt appeared. The one where Arch Linux tried to start all relevant processes. After that there are only mistakes. All startup processes are busy or failing. The only message i get is, that the filesystem, i think thats the root partition (ext4), is read-only or another error: some files for startup cannot be created because they already exist.
Getting to console is also impossible, because the system tries to start virtualbox additions, with an funny message, that it is busy and tries it again in 5 min (infinity loop). But shidt happens. I have read in another post that I can try another Linux System, mount my root partition and do an
fsck /dev/sda3 -p or -f
. But it says that all is clean (sda3 is root and sda1 is /boot). The filesystem is ext4, so i tried also fsck.ext4, but it also say all is clean.
After another boot i stoped at the position, where the fist error occur.
Mounting Local Filesystems
/etc/rc.sysinit: line 285: /etc/mtab: Read-only file System
next one:
Activating Swap
/bin/rm: cannot remove '/etc/localtime': Read-only file system
removing leftover Files
/usr/bin/find: cannot delete 'var/run/cups.pid': Read-only file system
After that message there are also al lot of analog errors.
I have no other idea than an dirty filesystem. Is there another possibility to rescue my system without an fresh install. Im sorry but i cannot log any messages at that state of boot. So it is not easy to get better informations about special error codes.
I have forget to give you some informations about my stats:
- actual stable arch kernel 2.6.38
- gnome 3
- thinkpad t400

With udev 168-1 I obtain this message during boot:
:: checking filesystems
fsck.ext4: no such file or directory while trying to open /dev/sda6 (my root device)
Possibly non-existent device?
***************** FILESYSTEM CHECK FAILED ****************

but fsck run manually says it's all clean.
I have to remount rw / partition and manually mount all the other partition, then I can switch to runlevel 3.
With udev 167-2 (and prior) I can boot without any problems.
I'm not sure it's a problem from udev, but downgrading it works for me.

Read only problem on forms

I'm having a problem when I set fields to read only in ApEx. The situation is there are several surveys to have user's fill out and they don't need to answer every question, and once the surveys are submitted, they are no longer able to be modified. I had no problems setting the fields to read only in that case, but the problem I'm encountering is that any question that had a null value left in it instead of being answered, the field is displaying as: []. I'd like to be able to change that so that it reads as not answered or something to make it more readable.
Is there a way to use a case when expression to clear this up? Thank you.

Thanks for the quick response.
I tried giving a case when using the null on one of the questions then set the form into Read Only mode, and it still displayed as []. I forgot to mention this part last time, and I'm sorry about that, but these items are Select Lists with a NUMBER column in the database, so I can't actually store words in the table for the null vales.
