Inferred Values and read only

We've been told that the default on the inferred value changed from version 9 to version 10 from read-only to writable. This messes us up on testing because it does not indicate which values are inferred and which aren't so it's possible values could get changed that were inferred.
This can be fixed by us re-factoring our code to mark the value read-only we are told. This is quite a bit of work though and it concerns me that a default was changed without regard to legacy code.
Is it possible that an option could be set to determine default value for inferred rules or a rule put in place that blankets all inferred values?

It sounds like you are authoring interview screens that include the inferred values. Is this because sometimes you want data to be entered into those fields (i.e. when no value has been inferred when that screen is displayed)?
If not, what is the reason for showing the inferred values on the screens, instead of at the end of the interview, and could you not just default the inferred fields to read-only in your screen definition?

Defaulting Values and Read-Only Items?

Hi All,
Brand new to APEX and trying to think of ways to get a few things working for me hoping you might have some suggestions.
1. Want to have a few items default upon the creation of a record.
- Created Date - have a column/page item that I would like to default/auto populate with the current date
- Create by - would like to have column/page item default with the login id of the user
2. Dynamically make page/items read-only.
- Once a record is created I would like to ensure that the only person able to edit the record would be the creator. I assume I can use the Read Only feature at the item level but am unsure of the syntax to use to make the item read-only for only the user who created/or is creating the record. Since I would like to be defaulting the "Create by" (see question 1) column to the login id of the user this should be plausible just not sure of the syntax to reference the current user id.
3. Passing a value to to bind variable.
- I have build a basic page with an Interactive Report and have made one of the columns in the Interactive report 'linkable' which launches a BI Publisher report by calling a Report Query. Currently in my report query I have hard coded a value in the SQL statements where clause to prove the theory works what I am struggling with is a declarative way to pass the value that I am clicking to a bind variable in my SQL statements where clause in the query.
Thanks in advance for any suggestions and appreciate your patience with an APEX newbie .. about 2 days old at this juncture. The more specific you can be on what to do and where to go is greatly appreciated.
For those interested in have greater control with your report layout BI Publisher looks to be a great options. I was able to getting by reviewing [how to document:|http://www.oracle.com/technology/products/database/application_express/howtos/howto_master_detail_pdf.html] on OTN. My challenge some in the fact that rather then simply being on the exact row that I want reported on I would like to simply click on a link in a list and pass that value as the bind variable.

Hi -
"1. Want to have a few items default upon the creation of a record."
This is typically done in a trigger at the db level.
CREATE OR REPLACE TRIGGER mytrigger
BEFORE INSERT OR UPDATE
ON mytable
REFERENCING NEW AS new OLD AS old
FOR EACH ROW
BEGIN
if (:new.CREATED_DATE is null)
    then
      :new.CREATED_DATE := sysdate;
    end if;
if (:new.CREATED_USER is null)
    then
      :new.CREATED_USER := nvl(v('APP_USER'),user);
    end if;
:new.UPDATED_DATE := sysdate;
:new.UPDATED_USER := nvl(v('APP_USER'),user);
END CREATE OR REPLACE TRIGGER mytrigger;"2. Dynamically make page/items read-only."
See 'APP_USER' in the Apex docs...
"3. Passing a value to to bind variable."
This is done in the report configuration in the Apex UI...
Session State Include application and session information.
You might want to consider reviewing some of the Apex docs and tutorials, I recommend this:

Good luck.

Set the value and read Only attributes just before PageLoad

HI All,
I am using JDev ver 11.1.1.4.0.
Is there any event in ADF equivalent to PageLoad event of ASP.NET where we can set the components property on page load.
When I try to access components in the beforePhase of any any Phase I get NullPointerException.
Thanks,
Rohit

Hi,
You can use dummy component with binding value attribute to bean with setter and getter in get method you can access components.
private String dummyText;
    public void setDummyText(String dummyText) {
        this.dummyText= dummyText;
    public String getDummyText() {
Implement your components access here..
        return dummyText;
    }

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.

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''';

Default value for Read-Only Picklist Field

Hi, all--
I would like to have a default value ("Undetermined") for the "Associated Account" read-only picklist value. I have an account record of this value for this purpose. This is because if there is no value in the field, the record will not be included in a report that includes the field. I do not want to make the field required at this point.
Field management doesn't appear to allow any default value for read-only picklists. Does anyone know how to get around this, either at the lead record stage or at the lead report stage (without resorting to an analytic, which won't work for what we are doing)?
Thanks.

That's a great question. It doesn't appear as though you can select it from the typical method of Admin | Application Customization | Lead | Lead Field Setup | Associated Account.
Have you tried creating a workflow to populate the field using Before Modified Record Saved?

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?

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.

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.

How can i read every"number" value and not only the 1st?

in the vi only the first "number" value(from the data acquisition)is read in the small loop.how can i make every value to be read?every value must be compared with the "numeric" constant,and,if greater the led must turn on.afterwards,when a value which is less than the "numeric" is found the led must turn off.please answer or send mail to [email protected]

The more I look at your program, the less I understand it.
Why are you setting number = number in a case if SO2 = ""? number always equals number.
In your sequence frames 1 and 4, you have no control over which write (date or time) happens first. Just placing one function to the left of another doesn't make it happen first if your wiring doesn't create data dependency. Review the section on Data Dependency in chapter 5 of the LabView User's Manual.
It looks you're writing to and reading from the same file using Write File and Read Lines from File.vi. Why read back data you just wrote? You have the data on your diagram. If you want to convert it from string to numeric, use a Sring/Number Conversion function from the String palette.
On Read Lines from File.vi (which I'm not sure you even need), you should use a shift register for the start of read offset rather than a local variable for mark after read (chars.). With a shift register, you can initialize it to 0 when the VI starts. Using a local, if you restart the VI, it will try to startup from where you left off the last time, but you just opened the file for create or replace.
In your sequence frames 2 and 3, why do you wait for the number to be less than the numeric before writing a carriage return to the file? Also, LabView has a End of Line constant which adapts to the expected value for the operating system. That's generally more flexible than a Carriage Return.
It looks to me like you're overusing control refnums. You don't need to use a control refnum and a property node to set or read a control's value if you can wire directly to the control's terminal.
I really don't understand what you're doing with pause and variants. I may be missing the point, but it looks like you made this much more complicated than it needs to be. Why not keep it a boolean?
For your pause-path, you open the file but never close it. You can lose data that way. You also open it using open function 3, create new file. You'll get an error if the file already exists.
On a general note, your diagram would be easier to read if you were more selective in how you routed your wires: you have wires on top of wires, wires running under sub-VIs, wires running in the frame of a while loop, wires running under labels.
I think there's a temptation to overuse sequences. I don't think you need one here. As I mentioned in my earlier message, case structures and shift registers will be more useful to you.

How to display the "display values" in READ Only mode for a SHUTTLE

Hi,
I have a form item of type *'Shuttle'* and using the following LOV.
   select DEPTNAME d, DEPTNO r
    from DEPTIn normal mode..it displays the department name and internally store the Deptno..
Now I converted this item to Read Only mode using Read Only Condition Type
the problem is as soon as it becomes read only...it displays the deptno....not the department name
            Department-   10:20:30How can I display the "display values" i.e the actual department name in read only mode..
            Department-   Department1:Department2:Department3Thanks,
Deepak

Hi,
It seems feature. Shuttle is span tag when it is read only.
Work around could be that
you compute display as text item with LOV display value according shuttle session state and show shuttle and this item conditionally depend case

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.

Barcode and Read Only Issue

Hi, I submitted this question in LiveCycle Designer and probably should have posted it here....
I have a form that was imported from a PDF document in Adobe LiveCycle Designer ES 8.2. I added a 3 of 9 barcode and the Default value is the form number (*1.764903.105NFS*). I do not want a user to be able to click on the barcode, so I made it Read Only. When this form is opened in Adobe Acrobat, I'm not able to click on the barcode, however, when this form is opened in Adobe Reader, I'm able to click on the barcode and the value displays (the form number) - which is what I do NOT want to happen. I have added Adobe Reader Extensions and I'm opening the form in Adobe Reader 9.4.
Also having the same barcode issue with forms that are designed in LC Designer.
