Entity attribute seems to reset on commit

I'm using JDeveloper 11g 11.1.1.2.0
I have View Object based on two entities. I have a transient attribute on VO which is a copy of
the entity based primary key of VO. I have an LOV configured on this transient attibute which I use
on my JSPX page. As soon as user selects value for this LOV based field a value change listener fires
which will execute the VO's query in custom appmodule method based on selected PK. This results in a
valid current record for VO and the other fields on the page are updated accordingly. However when
I commit the record I get a validateEntity error in that the PK entity attribute is null. Up until
Commit the attribute had a value. Anyone an idea what's happening here ?.
Thanks,
Kenneth

This sounds like you may be losing your internet connection on an intermittent basis.
Depending on how you have your Time Capsule configured to connect to the internet, there may be a few settings that you can check.
If you open AirPort Utility and click Manual Setup, and then click the Internet icon at the top of the setup screen, what setting do you see for Connect Using?

  • Trying to set the entity attributes in before commit and get the following

    i get the following error when i try to set the entity attributes before commit.
    JBO-28202: Entities invalidated in beforeCommit(). Need to re-validate and post.
    can somebody let me know, how to re-validate and post.

    I Suggest you set its Attribute on EOImpl, override doDML, and before call super.doDML set your Attribute. There is a special reason to set Attribute on beforeCommit?

  • DBSequence type no longer available for entity attributes?

    I'm puzzled by this, if not scared.
    Every version of JDev till 11.1.1.2.0 has had out-of-the-box support for DBSequence as an entity attribute type.
    When you set it for your PK, JDev disables a few options, automatically sets "refresh after insert" (and maybe other stuff) and handles everything about it.
    Now, I see that in new applications created with 11.1.1.2.0 that option is no longer present...!
    It's available only for apps migrated from previous versions.
    If you create a new application, you no longer have DBSequence in the Type dropdown.
    Here's what the documentation (Oct 2009 DevGuide, par 4.10.10) says:
    In the Edit Attribute dialog, you can set the value of the Type field to the built-in data
    type named DBSequence and the primary key will be assigned automatically by the
    database sequence. Setting this data type automatically selects the refresh after Insert
    checkbox.Where on Earth is this built-in data type named DBSequence in Jdev 11.1.1.2.0?

    Thanks Paul.
    It seems JDev broke my application.
    It only shows the native Java types in the dropdown, and does not show any of the Oracle types including Number, DBSequence and all the rest.
    (Note that all the connections I work with use the Oracle type map, of course - it's automatic.)
    I tried a new quick test with a new application and again, no Oracle types, just the java types.
    Then closed and reopened my applications as well as JDev and I can now see all the types in my quick test.
    However, my original application still "sees" no Oracle types, it's stuck with the Java types.
    I'll try to see if I can repair it in some way... I'll eventually put it down as one of the gazillion one-time bugs that JDev shows daily.

  • [JDev 9.0.3/JClient] ViewObject/Entity attribute: Display Hint ignored?

    I have a small problem with the ability to hide ViewObject/Entity attributes in generated JClient Forms. Hope somebody might know a bit more of this issue.
    When setting the "Display Hint" to "Hide" on an attribute (of either the Entity or ViewObject), the appropriate JLabel and JTextField (or whatever Swing control is used to edit the value) will not be hidden, neither at designtime nor runtime.
    I'm not (yet ;)) an expert when it comes to JClient, but it seems to me that when I tell an attribute of a ViewObject to be hidden, I would expect that the visible property of the appropriate Swing controls be set to false. [ setVisible(false); ]
    In some other thread [ http://forums.oracle.com/forums/message.jsp?id=1342592 ] I read that the problem might be related to setting the control hint AFTER the JClient Form was generated. However, in that same thread someone else suggested that the control hint is processed at runtime. So, I've tried both approaches: first setting the control hint, then generating the JClient Form and first generating the JClient form, then setting the control hint. Neither approach worked.
    However, I did notice that after I set the control hints, the JClient Form wizard allowed me to hide 'hidden' attributes (which indeed were the attributes which I had specified to be hidden). So that worked ok. But even though I unchecked the hidden attributes box, the end result was still the same: a Form with all attributes on it. Running the project revealed that the controls were not hidden at runtime either.
    Am I pherhaps missing something? Or else could this be a bug?
    (As the subject indicates, I'm using JDeveloper 9.0.3 Production Release.)

    Alright, consider this scenario:
    I have a ViewObject with some attributes and in particular the attribute 'X'. In the database table column X is NOT NULL and so attribute X automatically is Mandatory. (This is correctly generated by the BC4J wizard.)
    Next, I manually specify that attribute X is invisible (Display Hint). This should cause any bound Swing controls to become invisible when simply browsing the database. However, when inserting a new record, all controls associated with attribute X should become visible (since X is a Mandatory attribute). After the new record has been committed, the appropriate Swing controls become invisible again.
    I suppose that this behavior could be the same for non Mandatory attributes, but that's (somewhat) less important.
    In case you want a 2nd form in which existing records can be edited (including column X), attribute X should nolonger be invisible. Then the Swing controls bound to attribute X should be removed from the browse form and the 'insert capabilities' of that particular form should be removed as well. The new 2nd should be used for editing/inserting, while the 1st one is for browsing only.
    I realise that this scenario may contain a couple of flaws, but it's to give you an indication of what I'd like to be able to do with the existing wizards and attribute editors.
    Enjoy :)

  • Tracking entity attribute changes

    Hi,
    I need to keep track of entity attribute changes ( and also creation and deletion of entity itself) in a DB table. In ADFbc, is there a way to identify
    the changes in entity (attribute changes, creation of entity and deletion of entity) before and after commit?
    Example
    Employee entity with ID 747 was modified, Name attribute changed from A to B.
    New Department with ID 401 has been created
    Department with ID 911 was deleted
    Jdev - 11.1.1.5.0
    Thanks

    Are you talking about tracking the ADF BC entity or tracking changes done to data in the database through an entity?
    For the later, if you want to record every change in data I would suggest using database triggers on the database tables.
    If you rather do it in the ADF BC layer then you can override the EO's DoDML/remove and create methods to put the data about changes in whatever log you want.

  • Transient Entity Attribute as an Assoc

    Can I use a transient Entity attribute as an Assoc?
    I created an Attribute at the Entity level that is not mapped to a table. The entity is called FirstEndEntity.
    Then I created an Association between FirstEndEntity and OtherEndEntity. I used the attribute that i just created at FirstEndEntity, (so its transient) and the OtherEndEntity attribute is mapped to DB table.
    When I tested the assoc, the wizard complains, saying he cannot resolve the attribute that i just created?
    Is there a way around this?

    yes, you're right, I've tested it in 12.1.3 and error message was displayed.
    it seems it's a bug(bad bug ) in both 11.1.1.7 and 12.1.2. and now what can I do? is there any way to display the the error message?
    Regards

  • Entity Attribute Validation

    I have an entity with many attributes but one of them is with name "CODE". Now i want to validate it that it should not be duplicated. What i did is created new Business Rule of List type For Entity Attribute and with operator "Not In" and selected "Query Result" and gave query for that. it works fine for all those which have been committed to database but if i have created multiple records and yet not committed, it does not work for that. I also tried option of ViewAccessor but that was not working too.
    Please help me

    If you use a DB the natural thing to do is to define a DB constraint (in your case a unique index). This will be recognized by the framework and the constraint should be seen in the EO.
    The other part is that you can't be sure if an attribute is unique as long as you do not commit (or at least post) it. only then the validation can check. I don't know if you can check not commited data from other users.

  • Oracle.jbo.PersistenceException: JBO-26010: Invalid Entity Attribute Name "" specified for the View Attribute ""

    HI, I'm using JDEV 11.1.1.6.0
    I am encountering this error msg on one VO
    oracle.jbo.PersistenceException: JBO-26010: Invalid Entity Attribute Name "CorrespondenceAddressFlag" specified for the View Attribute "AddressDetailsVO"
    I have searched for similar problems for others and have checked the relevant XML file and have seen that the entries are correct.
    If I delete this attribute and add it again, the error come up for the next attribute.
    Earlier the EO had a few attributes then according to further requirement changes, we add new attributes to the Table and Synchronized the EO's.
    Then added these Attributes to the VO. This application Runs fine when tested in AppModule but when dropped on page, it gives the above error.

    Just to confirm that this is not a Library or deployment setup problem, Now, I changed the deployment scope to include business components in the ViewController to just to be sure it was being picked up in the ViewController too. I Created a separate AppModule in the ViewController and Added the VO to it, It Ran Properly including the Addition and Commit Control.

    You don't need any kind of security software.
    Just surf the web carefully, pay attention to where you're going and don't install anything that you don't recognize.  If you are asked to enter an admin user name and password, DON'T.  Unless you know for sure that you initiated the installation from a known and reliable source (like Apple).
    Mac malware relies on social engineering.  No amount of security/anti-virus, blah, blah, blah software is going to help.

  • DBSequence entity attribute type not available

    Hi OTN,
    I want to set an entity attribute type to DBSequence. But there's no such type in a drop-down list, only Java types.
    I tried to set the type in source manually but at runtime framework doesn't assign a negative integer to the attribute at Create operation.
    In simple test application DBSequence type is available and negative integers get assigned.
    I have found a proper thread (Re: DBSequence type no longer available for entity attributes? but the solution there is to recreate the whole datamodel. That isn't suitable for me.
    Maybe there is a better solution now?
    Jdeveloper 11.1.1.2, ADF BC
    Thanks.

    I logged Bug 9380578 - "SQL FLAVOUR" AND "TYPE MAP" CAN BE CHANGED IN "PROJECT PROPERTIES"
    (published in My Oracle Support).
    NB: in JDeveloper 9.x, it was possible to change the "SQL Dialect" (as it was called at that time), but the ADF BC objects and the custom code weren't changed;
    hence it was decided to gray out that choice after the Project creation.

  • Display entity-attributes and global-attributes in the same screen

    Hi,
    I have a question about entity.
    Is it possible to display in the same screen, entity-attributes and global-attributes?
    thanks
    Rosalia

    Hi Rosalia,
    You can only display attributes from the current entity and the entity or entities that it is contained by (the parent entities).
    So if you had the following data model
    Global
    ..the person
    ...the income
    the person is contained by global.
    the income is contained by the person (which is contained by global).
    If you want to create a person-level question screen, you can display global attributes on that screen by using subsitution like %global_field_1%. You cannot, however, input global attributes on that screen (ONLY attributes belonging to the person)
    If you want to create an income-level question screen, you can display attributes from the person such as "tell us about %person_name%'s income..." as well as global attributes. Again, you cannot input person or global attributes on that screen (ONLY attributes belonging to the income)
    However it only works from child-to-parent containment relationships! You cannot have a global question screen which loops through the person instances and displays attributes from the person, or from the income out-of-the-box.
    We have managed to implement this using custom controls.
    You can map individual attributes back up to the parent level, and then display them,
    such as
    the first person's name = InstanceValueIf(the people, the person's name, the person's id = 1)
    the first person's name is now a global attribute and can be displayed on global question screens.
    Hope this helps!

  • Bug: unable to rename entity attribute (jdev903)

    Hi,
    I have an entity and a view on it.
    One of the entity attributes has the wrong name, so I tried to rename it, but jdev gave me a warning that it couldn't rename the attribute because the view is dependent on it. Sounds fair (although I wish it would rename the attribute in the view along with it, (refactoring)).
    Then I removed the attribute from the view, and try to rename the entity attribute again. It still can't rename it! I've verified twice to see if the attribute was actually removed from the view, which it was, so this is definitely a bug.
    Greetings,
    Ivo

    Ivo want's to rename the attribute in the entity object without first removing the attribute from the view object. That this isn't possible right now probably isn't a bug, because in your scenario you keep that in mind, so you manually first remove the attribute from the view object. But it would be nice if JDeveloper automatically renames the attribute in the view object too (instead of "complaining" about the dependency). And if you for example remove an attribute from an entity and a view object depends on it, it will ask you to remove the attribute from the view object(s) too etc.

  • ADF JDeveloper 10.1.3.4.0 Entity Attribute validation not propagated to UI

    Hi,
    I'm trying to use entity attribute validation in an ADF Faces / ADFm / ADF BC application. However the validation error
    is not propagated through the BindingContainer to my ADF Faces Page. When I customize and override the DCErrorHandler that
    is registered on the BindingContext the reportException() method doesn't fire.
    Anyone have an idea how to debug this Validation error gone lost ?.
    Thanks,

    Hi,
    is it getting propagated without your custom error handler ?

  • JBO-26010: Invalid Entity Attribute Name

    Hi All,
    The requirement is to add a new field on the page but that field is not getting selected in the core EO, so I have extended the EO and than extended the VO based on that extend ed EO.
    After that I followed usual steps to import then personalised and added the new field ...bounced every thing but when I am testing got following error:
    ## Detail 0 ##
    JBO-30003: The application pool (oracle.apps.pon.negotiation.creation.server.NegotiationCreationAM) failed to checkout an application module due to the following exception:
    oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.PersistenceException, msg=JBO-26010: Invalid Entity Attribute Name "Description" specified for the View Attribute "XxAuctionHeadersAllVO"
    ===========
    When I checked the "XxAuctionHeadersALLEO.xml" it has only entry of new attribute. But in "XxAuctionHeadersAllVO.xml" it has the complete SQL ....so is that can be a problem?
    I have run the query from "XxAuctionHeadersAllVO.xml" in toad and it works fine.
    Thanks!

    Yes it is...:-)
    Anyways thanks for the reply..
    The Base EO - AuctionHeadersALLEO which I have extended to XxAuctionHeadersALLEO
    I have already performed both the steps suggested by you (i.e. option 1) so after Substitute the custom VO "XxAuctionHeadersAllVO" on top of standard VO "AuctionHeadersAllVO" when I tested the change I have got the above error : JBO-26010: Invalid Entity Attribute Name "Description" specified for the View Attribute "XxAuctionHeadersAllVO"
    So in custom VO (and also in standard VO) select it's just references it as "AuctionHeadersALLEO.DESCRIPTION" but the field is in AuctionHeadersAllBaseEO.xml not in AuctionHeadersALLEO.xml
    so I don't understand how it works in the standard product?
    Is it any better? Or do I have to be more clearer :-(
