How to use a UUID type number instead of sequence as a default value in the attribute of the view object?

Hi all.. I want to use a type UUID number in an attribute of the object from view as default value to generate the unique field... so, how can I generate random uuid?

Well, the UUID looks like as follows:

Example 1: 067e6162-3b6f-4ae2-a171-2470b63dff00

Example 2: 54947df8-0e9e-4471-a2f9-9af509fb5889

You can play withgetMostSignificantBits() and getLeastSignificantBits() , this is the long values and you can combine them in order to generate BigInteger, as described here:

https://gist.github.com/berezovskyi/2c4d2a07fa2f35e5e04c

Then just use this value in the constructor number:

    Hello
    Make a right click on the application module (yourAM in the model project) and press Run, then you can check if your ViewObject works or not.
    Note:
    Typically create viewObject using based EO or query based how did you create viewObject

    For the date, you can use groovy expression adf.currentDate to set the current date. reference http://adfgouravtkiet.blogspot.in/2012/11/how-to-set-default-values-for-entity.html

  • Block initialization parameter default value of the session variable used in default prompt as "(toutes les valeurs de colonne)" "

    Hello

    I have a business requirement for a dashboard that we built location to get the users that belong to a certain geographic location to the default view of the dashboard with guests together in their geographic area.  He is just giving them a default view to enhance their experience when they connect each day.   Because of the way that we put the default value for the period of time they watch, with the HELP of SAUVÉ the CUSTOMIZATIONS IS NOT AN OPTION.

    I created the default values for the prompt called "area" in a block of initialization. This variable is called V_USER.

    My problem is that only about 80% of users have a value of 'Area' in the hierarchy of our employees.   I would like to someone else by default "(toutes les valeurs de colonne)". "  I was unable to understand how and where do.

    Some of the things I've tried:

    (1)Setting the default value in the initialization of an empty space block ("in SQL)
    (2)Setting the default value in the initialization "(toutes les valeurs de colonne) block '"
    (3)Setting the default value in the initialization block 'null '.

    None of them have worked and the result is that the user who does not have an area ends with a load of zombie dashboard, and while the guest gave rise to fashion "- select value -", the user must press "Apply" again to get the dashboard to display the data.

    The text which lies behind the encircled area in green below correctly becomes the value of the variable to V_USER (it is empty as default and I don't have a box).

    For @{biServer.variables ['NQ_SESSION.]} {[USERS ']} the default zone must be @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {}

    In the red circles below you can see that the guest actually becomes a value: *) nqgtu(* )


    The illustration below indicates the default value for a user without a box. the second quick block is not updated until you press on apply again...

    Thanks for your comments.  I was not able to make this work for my needs.  I have however to solve the problem by changing using a 'SQL result' for my default selection.  Then I created a query that returns rows NULL unless there is a correct answer:

    SELECT 'Service Delivery MOS '. "' Organizational hierarchy. "" Area ".

    "MOS DELIVERY."

    WHERE ("organisational hierarchy". ("" Area number "> 0) AND ("Service Delivery MOS". "Organizational hierarchy" "." " Zone' = ' @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {} ")"

    The "returns no line' I mentioned above resulted in all values being selected.

  • Default value for the select list of type of form elements

    Hello

    I do not work with Apex that mutch, so this may be a simple question... but I still need help.
    I have a form, in this form, I have a question P19_ONTVANGER_ID, this is based on a LOV.
    This LOV is on a table that has a field of username with the value of APP_USER.
    The table looks like:
    ONTVANGER_ID this is the PK and is going to be the return value from the LOV.
    NAME is the display value for the LOV.
    USERID is the column APP_USER.

    What users would like to get is that if they create a new record, the default value for the P19_ONTVANGER_ID field is their own ONTVANGER_ID.
    But they must also be able to select another user.

    hope there is someone out there that can and will help me.

    You can select the Type of default value as the body of the PL/SQL function

    and to add something like that

    declare
v_return number;
begin
  select your_id

  • How to give the default value for an attribute in the OPA

    Hello

    I need a default attribute boolean to true at the beginning of the session of the OPA. I need to use it to control the visibility on some pages.

    Can someone please throw light on how to best implement this?

    Thank you.

    You have a few options (as always with the OPA!)

    If you use determinations of Web and that you have defined your own screens, then the easiest way is to define a default in the screen - you can either do a default static or dynamic based on an attribute is proved by a default rule.

    If you want a value by default when you debug without using screens, so you're better off just writing a rule to set the default value. It's kinda interesting with a Boolean value as you do not need to tell the value of the attribute OPA - it is inherent in the name of the attribute. For example, if you had a conclusion "control is visible" (with no = "true" or whatever it is) it would be set to 'control is visible' to 'true '. Set it to false, you simply need to type "control is not visible" - which actually (thanks to OPA assuming a 'subsidiary conclusion') defines "control is visible" to "false".

    You can then replace it in the debugger of via a screen issue (if you force the question).

    I don't know how it would work with server of determinations if you had a default value proved by a rule, but has also provided a value in the data - maybe someone else can clarify if the rule takes precedence over the input data? My usual approach is to try locally in OPM and see (using something like SOAPUI to integrate with the determinations OPA server web service). If that's the best way to implement this course (or indeed if using a default value of visibility control screen is best practice) is difficult for me to say - I am a relative beginner!

    Hope that helps a little...

  • How to create LOV not based on an attribute of the View object?

    Hello

    I have created a form of research made hands, and I want to create an af:inputListOfValues.

    I have:
    -a read-only-view-object to get the values of BD LOV.
    -tag af:inputListOfValues (droped component Palette).

    How can I create the listOfValuesModel in the layer of links? (the inputListOfValues is not based on an attribute of the View object).

    Possible solutions.

    1. Add a dummy VO in the layer of model with a single attribute. Create LOV to the attribute and use this attribute in your view.

    How can I select for example empno default 1000?
    Thanks in advance.
    Jacob

    Jakob,

    In this case, your default value is

    HTP.prn (')

    However, you can set the default value in the loop as you want. You just say that is your default - first, second, third...

    In the list select ajax there's no submit and no calculation of values then I assuem your default is the punch one you wan to display when a selection list has been changed?

  • How to set up the default value in the ADF option button?

    Hi all

    I use 11.1.6

    I want to put the default value in the radio button (in the UI).

    EX: I have a SelectOneRadio as sex

    In these two values, one is male and secondly a woman.

    I need to see the default value of the male part of the user interface.

    I mean when the loading of the page it should show male is checked in the user interface part?

    Someone help with this task?

    Ok

    So in your BinderSolutionsBean, you have an attribute called;

    String scenType;

    public String getScenType()...

    What you need to do is to initialize scenType to rtb;

    public BinderSolutionBean {}

    String scenType = "rtb";

    .

    .

    .

    }

    Hope this makes sense;
