Annoying error: VO/EO read-only until you correct errors

Hello all,
I see this problem in both JDev 10.1.3.1 and 10.1.3.3, and I'm wondering if others have experienced the same problem. After a few code/run/code/run cycles (I've not been able to reproduce with a specific set of steps, but it happens quite frequently), I start to get the above-mentioned errors when trying to edit ADF BC View Objects/Entity Objects. The specific error that it complains about is missing java files (Impl, RowImpl, etc). I can "fix" the problem by quitting JDev and then deleting the classes folder for the BC objects, but it's quite annoying.
An update - when I get into this scenario, and I create a new object - I find that it is putting the XML files/java files for the new EO/VO in the classes directory, not the src directory.
Has anyone else seen this?
Regards,
John

Hi Venkata,
Same thing happening to me, R12.1.3. Please let me know if you find anything on this.
I tried some steps in this forums related to this, but no change. however I am not worried, customization works perfect after extension, but wanted to know the reason.
Thx..

  • Make field read only untill value within pciklist is choosen

    Hello,
    I am trying to establish if it is possible to make a field read-only until a value within a pick list is chosen. Basically we have a pick list called structure and if the field value called "Aligned" is selected then I want the text field called Aligned Name to be available for import all other times this field should not be available.
    Has anyone done anything similar? I'm guessing that this could only be achieved through WF but I haven't been able to find any code to make fields read only.

    For those of you unable to download the document from MetaLink3 here it is:
    As an example to illustrate this requirement, let’s say that once there is a checkbox field called "My_Check_Box". When this field is checked, the "Account Type" field need to become a required for entry by the user. To do this follow these steps:
    1. In the Admin> Application Customization, select the appropriate Object and go into the Object Field Setup.
    2. Edit the field called "My_Check_Box" and enter a Field Validation expression so it uses the following expression:
    =[<bMy_Check_Box_ITAG>] AND NOT([<AccountType>] IS NULL AND [<bMy_Check_Box_ITAG >]='Y')
    3. Enter an explicit error message.
    This expression means that when the checkbox field is checked, the Account Type becomes required. Your custom error message will be raised when checking the checkbox, leaving the account type unpopulated and trying to save the account record.
    4. Edit the Account Type field and enter the following expression as Field Validation:
    =[<AccountType>] AND NOT([<AccountType>] IS NULL AND [<bMy_Check_Box_ITAG >]='Y')
    5. Enter an explicit error message.
    That validation handles the user case where a user changes the Account Type value from a NOT NULL value to a NULL value. Your custom error message will be raised when emptying out the account type from a populated value to nothing while the checkbox is checked and trying to save the account record.
    Note that the expression in both fields validations begins with the field variable on which the statement is being written.**

    Mina,
    You can use LiveCycle Designer's Action Builder to easily achieve this.
    Please go through online documentation for the specific version of LiveCycle Designer that you are using.
    It is intuitive and very easy to use Action Builder (You will find this option under Tools Menu item of Designer).

  • F400917: The current configuration is not valid for this feature. This feature cannot be used until you correct the configuration.

    Hello,
    We recently changed to TFS as our bug tracking system and trying to understand how to change the existing states of Bug\Add new states. We installed TFS 2013 Update 4 and followed below process to change state values. For example, I would like to change
    Bug State value of "Done" to "Closed",
    1. witadmin exportwitd /collection:"http://MyServer:8080/tfs/DefaultCollection" /p:MyProject /n:Bug /f:C:\TFS\bug.xml

    3. witadmin importwitd /collection:"http://MyServer:8080/tfs/DefaultCollection" /p:MyProject /f:C:\TFS\bug.xml
    Then we see below error in Work -> Backlog
    TF400917: The current configuration is not valid for this feature. This feature cannot be used until you correct the configuration.

  • External hard drive read only unless you unplug and replug in

    I've got an external firewire hd (fw 400 with an adapter) connected to a MacBook Pro 2009 running OS X 10.6.2. It's been working flawlessly until recently. I'm not sure what happened and I don't think it's the result of any system upgrade or modification, but now, at startup, the drive shows up as read-only. But, if I eject, unplug, and replug it in, or eject, turn if off, and back on, it mounts correctly as read/write. Get Info on the drive shows that it should be read/write. I've tried repairing permissions and doing a repair disk from Disk Utility, but no problems are found.
    Any idea on what the problem/solution is?

    I'm not sure where the issue is but you do you do have it running. One thing you can do to see if it's the computer or the drive is to get another FW drive and connect it and see if it works. If the Mac automatically detects it (like it should!) then that tells you it something with the original drive and if it doesn't then it's obviously something with the MBP. If you take it to an Apple Store and explain the issue they can probably provide another drive to test it out.
    If it turns out to be the drive (that's my guess) then it might be a power supply problem or the FW connection, a hunch tells me it would be the power supply.
    At least you are finally making progress and can use the drive though!

  • How do you set Mail to mark a message as "read" only when you open it

    I'm using Apple Mail. Works great, but I have one big issue I can't figure out. I want my messages to be marked as read ONLY if I double click or actually physically open the message....not when I click it once with the mouse or if it gets selected in the inbox message pane. The way it's set up, all my mail is read the minute I click on it. This is extremely annoying and I can't find anywhere where you can set this preference. HELP.
    does this make sense to anybody??
    OSX Tiger 10.4.7

    The OP's question makes sense and Scott's comment is correct. You can have Mail setup so that there is the list of folders on the left, the list of emails in that folder in the top right hand side and the selected message in the pane below that on the lower right hand side. In that case clicking on a message in the list of messages will display it below and Mail will deem you to have read it. On the other hand if you drag down the divider and get rid of the pane in which the message displays then selecting it does not mark it read. Double-clicking it should bring it up in a new window and cause the message to be marked read.
    Basically Mail marks the message read when it has displayed (some of) the message in some place (ie a separate window or the lower right hand side pane) where you could have read it

  • Boot: read-only filesystem error

    Hi,
    when booting this happens with 3 different arch installs.
    INIT: version 2.06 booting
    /etc/rc.d/functions: line 22: /dev/null: Read-only file system
    /etc/rc.d/functions has this on line 22: TERM_COLORS="$(/bin/tput colors 2>/dev/null)"
    I'm guessing I've done something bad at some point...
    Any thoughts?

    The normal boot sequence reports read/only until the kernel and support are fully loaded.
    This prevents any error intro by writes inadvertent or otherwise....

  • Time Machine "read-only" error across multiple drives

    Hello,
    I've been having an ongoing problem for more than a year now. I continually get a "read-only" error message from Time Machine. To be specific, the message is: "Time Machine could not complete the backup. Files can’t be copied onto the backup disk because it appears to be read-only. You may need to repair or reformat the disk using Disk Utility. If the disk can’t be repaired, you must use a different disk for backups. Open Time Machine preferences to select a different backup disk."
    The problem is, this has happened with three separate backup drives. They are all G-Tech 2TB 4th Generation G-Drive external hard drives. So I'm wondering if there may be a Mac OS software problem, or perhaps a hardware problem.
    There's a lot to this story, so if you're game, read on.
    First, about a year ago, I noticed that my Mac Pro frequently spontaneously ejected the backup drive, for no apparent reason. I didn't deal with the problem right away because I was having other, pressing troubles with my display (which took forever to solve).
    In early-mid 2013, I tried a few disk repairs of my backup disk, as well as erasing the disk (and correctly formatting as Mac OS Extended Journaled). The disk was failing to mount at that point, so G-Tech sent me a replacement drive (a refurbished drive of exactly the same type).
    With the replacement drive, I was getting the same "read-only" message. So I tried a few times erasing/reformatting/repartitioning this drive. No luck.
    So I was sent yet another replacement drive. I experienced the same problems, and in addtion, I once got a message saying the backup drive was full when it actually wasn't. So I tried a) using a different firewire cable, b) using this different cable on a different port. Same problems.
    In the meantime, I did some backups with an old Glyph drive, using the same FW800 port, and the same cable (the 2nd cable), and I had no problems. The reason I don't use this Glyph drive as my normal backup drive is that it is only 500 GB and not large enough to back up all three of my MP internal drives.
    A couple other items of note: back in August of 2013, one of my MP's internal hard drives had to be replaced (it was determined to be having multiple input/output errors). Also, I've had a intermittent problem with the MP spontaneoulsy ejecting a couple different Lexar USB flash drives, even after I reformatted them repeatedly (but this has never happened with my ADATA flash drives). I suppose these things may be unrelated, but for the sake of completeness, I thought I'd include them.
    So it seems like maybe it's a compatibility issue the G-Tech Drives? I'd be surprised...but I'm stumped. Anyone have any ideas?
    Thanks.

  • Read only record sets ?

    We're using a function to return a ref cursor back to VB.
    Works great until we try and update it. As soon as we try and update the record set we're getting an error "Multi-step operation generated errors. ". It looks to us like the record set is read-only. We've tried using an in-out parameter to a procedure - same problem. However, it works fine as long as we pass the sql instead of a call to a function or procedure.
    We don't really want to have to pass the sql.
    Can anyone help with this ?
    Thanks,
    Tricia.

    Ref cursors that are returned to an application from a stored procedure are read-only if you're using ODBC or OLE DB. I believe that the beta .NET native provider will allow you to update returned ref cursors, however.
    The reason it works when you issue straight SQL is that the driver actually modifies your SQL statement to get the ROWID's for all the rows. Then, it's able to update rows by building its own SQL insert statement.

  • Time Machine appears to be "read only"

    My Time Machine suddenly turned into a Read Only device.
    "Files can't be copied onto the backup disk because it appears to be 'read only.'"
    "you may need to repair or reformat the disk using Disk Utility. If the disk can't be repaired, you must use a different disk for backups. Open the TIme Machine Preferences to select a different backup disk."
    My computer Hard Drive is still running fine. Can I save a backup of the TIME MACHINE backups and load them into a new Time Machine drive.

    Why not first repair the drive using Disk Utility?
    Open Disk Utility in the Utilities folder. After DU loads select the TM hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your TM volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU.
    The problem of having a TM drive revert to read-only is not new. There is this past fix:
    What to do if Time Machine reports you don't have permission
    This was posted in the Apple Discussions by V.K. I have only modified it slightly to be more generic.
    The problem seems to be that 10.5.6 changes permissions on a file so that even the root user doesn't have write peivileges. I have no idea why they did this. The workaround suggested in [an]other post will probably work, too, but i did something less drastic. Instead of deleting the file I changed permissions on it, and it worked just fine. An added benefit is that the permission change seems to stick, so you don't have to delete the file every time you change a drive.
    [Open the Terminal application in your Utilities folder. At the prompt [enter] the following command:
    sudo chmod 644 /volumes/"TM drive name"/.xxxxxxxxxxxx
    The name of the file .xxxxxxxxxxxx is based on the MAC address of your computer and will be different for every computer. Put the name of the TM drive in the above and keep the quotes.
    You'll have to enter your admin password (which you won't see) which is normal.
    This was edited by Kappy just for cleanup.
    Enable Finder to Show Invisible Files and Folders
    Open the Terminal application in your Utilities folder. At the prompt enter or paste the following command line then press RETURN.
    defaults write com.apple.finder AppleShowAllFiles TRUE
    To turn off the display of invisible files and folders enter or paste the following command line and press RETURN.
    defaults write com.apple.finder AppleShowAllFiles FALSE
    Alternatively you can use one of the numerous third-party utilities such as TinkerTool or ShowHideInvisibleFiles - VersionTracker or MacUpdate.
    Also, see User Tips for Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.

  • Unable to save Word documents when accessing them directly from the site because the document never converts from a read-only even though the User chooses to enable editing

    Issue has only popped up recently and cannot reproduce in a Test environment.  Unaware of any SharePoint changes, so hoping someone can point me in the correct direction.
    Previously Word document did not have to be physically checked out, but rather the editing of the doc also checked out the doc in a document library. This is the way we want it to remain –
    no manual check-out process. Now if a doc is edited without being checked-out, there is an issue with the process as the application thinks the doc is read-only (message received when trying to save the doc) even if enable editing is selected. The
    following message appears when you try to save the document:
      This message can appear if you have been editing a file that was opened as read-only. A file opened as read-only will have (Read-Only) appended to the file name as it appears in the title bar of Word. You can still save the document, but you must
    save it by using a different file name. If you use Windows Explorer to change the read-only properties of the file, while the file is open in Word, it will not enable Word to save the file. Word must open a non-read-only version of the file in order to save
    it by using its original file name. If you have not made any changes to the file, you can close it, and then use the following steps to make the file writeable. 1. Click the File tab, and then click Open. 2. Browse to the file and right-click it. 3. Click
    Properties, and then clear the Read-Only check box. 4. Reopen the file. If you have made changes to a read-only file, you can save it, and then use the following steps to give the modified file the original file name. 1. Click the File tab, and then click
    Save As. 2. Enter a different file name, and then click Save. 3. NOTE: Adding "Rev1", or "Mod1" to the original file name may help you to remember it later. 4. Click the File tab, and then click Close. 5. Open Windows Explorer. 6. Browse
    to the original read-only file. 7. Rename the read-only file. 8. Browse to the new file. 9. Rename the new file to the name of the original file. Do not delete the read-only file until after you have determined you no longer need it.
    Previously, when check-out was optional, a file was checked out automatically when someone opened it for editing, unless it was already checked out. The editing commands notified the User that the file is being/was checked out.  The real issue is the
    word doc can no longer be saved as the application still believes the doc is read-only.

    Hi, 
    According to your description, you give the domain admin full control over files on the old file server, but you cannot move the files to the new file server. After pull the files from the old to the new file server, the domain admin can only read the files
    on the new file server.
    How did you move the files from the old file server to the new file server? Did you setup replication between the two file server or use robocopy? 
    Please check the files permissions on the new file server to see if the permissions are changed, then share the folder on the new file server to everyone to see the result.

  • SMB share read-only after upgrade to 10.6.4

    since i upgraded my MBP to 10.6.4 i can access our samba shares only in read-only mode.
    i'm connecting with the following string:
    cifs://myUsername@servername/aFolder/anotherFolder/myFolder
    this connection used to work since 10.3 or 10.4 up to 10.6.3, but now i'm getting a read-only volume ("You can only read" in the finder's get info window).
    any hints what i could change to make things writeable again?

    maybe an important additional info:
    the SMB share is mounted under /Volumes using my local MBP user/group setting.
    on the unix box where this share is located, i'm using a different username ("myUsername"), hence the cifs://myUsername@... in the server address string.
    since this connection always worked until 10.6.3 i have no idea if this share used to be mounted for root/admin (or other) - i never checked those permissions/owner settings before.
    THIS IS /Volumes:
    drwxrwxrwt@ 5 root admin 170 14 Jul 12:55 .
    drwxrwxr-t@ 38 root admin 1360 23 Jun 08:38 ..
    lrwxr-xr-x 1 root admin 1 11 Jul 10:53 Macintosh HD -> /
    drwxrwxr-x@ 24 root admin 884 18 Jun 19:39 Users
    *dr-xr-xr-x 4 mbpuser mbpuser 16384 14 Jul 12:52 myFolder*
    loging in on the remote server (using Terminal.app and "myUsername" + password) i have full r/w access on myFolder and all subdirectories. it's only the mounted share on the MBP that is read-only.

  • DBFS in read-only tablespace as LOB archive solution

    I am trying to come up with an architecture to solve the following requirement
    1. transactions will have LOB attachments
    2. Transactions will be live for short period of time, after which they will be 'closed'
    3. all transaction details, including LOBs must be kept for minimum of 7 years
    4. want to minimise backup requirements, so that we aren't backing up large amounts of basically static data.
    Here is my proposed solution
    1. table for the LOBs will be in the 'live' part of the database.
    2. There will be a DBFS created in the database as DBFS SecureFiles Store
    3. The tablespace holding the DBFS_SFS will be read-only.
    4. Periodically (monthly?) the DBFS_SFS will be made read-write, the LOBs from closed transactions will be moved from the 'transactional LOB table' to the DBFS_SFS and replaced with DBFS Link
    5. DBFS_SFS will be made read-only, and full database backup performed
    6. subsequent backups will skip read-only, until the next iteration
    have I missed anything that may prevent this from working?
    phil

    Thanks for the reply
    Firstly, the app availability is expected to be 12x5, so the plan would be the full backup would be during the weekend, but I appreciate the issue re backup timing
    What I would really like is if there were some way to have the DBFS SFS in a separate database, and register it as a hierarchical store, but there doesn't seem to be a way to do that. Even if I was able to write the appropriate DBFS Store Provider (a la the DBFS sample store at http://www.oracle.com/technetwork/database/application-development/522110) , you run up against the 32K limit of dealing with LOBs in a remote database (unless I have missed something somewhere)
