A display/entity object assigns default values to view another object

I have a table as follows:
Table A with attributes:
ID, name, value1, value2,..., Value20

Table B with attributes:
ID, Env

Assume that the Table B has 5 rows: (1, 'DEV'), (2, 'BT'), (3, 'SDEV'), (4, 'PDEV'), (5, 'UAT'),

What I need, it's when I create A table line, Value1 attributes by Value5 in table A are populated by the value of the attribute Env of each record in Table B. So, in this example, the new line of table A will be:
(1, 'Env affected', 'DEV', 'BT', 'SDEV', 'PDEV', 'UAT', null, null,...)

I think to generate classes customized for A tables display objects and B and expose methods so that a bean to support, I can create a table A line and fill the Table B table.

You have a better approach to do this?

Thank you.

When you post on this forum always to indicate the version of JDeveloper you use please.

Assuming that JDev 11 g + I can think of a few ways to do this. However in a pod of support would be inaccurate, because you are mixing view logic with business logic. My suggestion:

(1) to the table entity object (EO) create an accessor to display of the View object to table B
(2) for table A EO generate the associated EntityImpl. Be sure to include the create() method.
(3) in the EntityImpl, look for the get accessor method to retrieve the results of the view accessor install you in #1
(4) in the # 2 create method, call the #3 accessor, walk records (eventually returned by table B) via getter accessor method view, learning the attributes of the table of A OS

  • Startguidence - make a simple change in default values of an entity object

    Hi all!

    I want to do non-static values by default in some of the fields of an entity (ExtBankAccountsEO) object.

    I have JDeveloper on my pc, but not on the server where Oracle Financials is installed.

    So which is the best way to proceed?

    My first thought was to decompile ExtBankAccountsEO.class, add a create() method and then compile it on the server.

    But without changing ExtBankAccountsEO.java and compilation with

    javac - cp classes12.jar:classes ExtBankAccountsEOImpl.java

    I get an error of type

    ExtBankAccountsEOImpl.java:395: cannot find symbol

    symbol: class string

    location: oracle.apps.iby.schema.server.ExtBankAccountsEOImpl of the class

    public string getAttribute8()

    And similar to exception, subject, date and number.

    Am I missing something in the classpath or this is not possible?

    It comes to specific issue OA.

  • The default value based on the field from another table to a custom object

    I'm trying to set the default value to a field in the custom object to the value of a field of account. I tried the syntax 50 ways different and just don't get the case. The label for the account field displays the form of s/n, the integration of the tag is ltDBA_ACCT and it appears in the fx reports area as Account.Text_22.

    The field of custom object that I am triying update is also called s/n, which was originally the required field 'NAME '. The name of the table, account, should it be included? Do I need a function to the field?

    I've updated the external ID using the line with syntex < ID > ID (at least higher ID) so I know that it is possible to define a default value, but s / < n >, < ltDBA_ACCT >, 'account '. "" S/n "and so on are simply not working.

    If anyone knows how to get into what I would be really grateful for the help.

    OK, so if you default a field to the value of another object, you must use the JoinFieldValue function. I think you understand that, based on your original post, but I want to be sure you do.

    Then this won't work by default if the folder is created from the object that you want to join the because a default works in record creation and the ID must be available so that it works correctly. It will not work if you choose the record of the related object after that registration of the custom object is created. You can set the default after, but that does not meet your requirements.

    The syntax of the default are the following: JoinFieldValue (ref_record_type, foreign_key, field_name).

    In your case, ref_record_type is '', foreign_key is [] and field_name is ''. The best way is to determine what is the name of the field to create a new workflow for the account and use the Workflow Rule Condition expression builder to choose your field ("DBA") in the list. The value returned by the expression builder must be placed in the field_name variable in the function JoinFieldValue (minus the parentheses and quotes).

    Give it a shot and let me know how you do.

  • Reproduce the value of the entity object

    Hello

    I have the association between two entity objects. I want to set the attribute on the child entity object whose value should contain one of the values of field of object parent entity. Can I do in the studio or I need to write custom code.

    Thank you...

    I think you may be a little more precise here. Is this just for new lines? Or do you want the application to automatically change of lines (if, say, the parent changes, or the queried data has the attribute set properly) to meet this requirement? I'd say the latter is enough almost impossible to do without some Java, but the first can be made with Groovy using the default attribute. Make sure THAT the cardinality of the association is defined as appropriate; If the '1' or '0.1' is defined as ' * ', the following will not work (even if the association is really just as a line on this side).

    (1) in the definition of child entity object, change the attribute and set the Type of "value" to "Expression".
    (2) in the 'Value' field, enter the expression "AssociationAccessorName.SourceAttrName", where "AssociationAccessorName" is the name of the accessor of the object entity across the definition, and "SourceAttrName" is the name of the attribute that you want by default, for example: "Departments.DepartmentId.

    Hope this helps,

  • Firefox is the default value. Whenever I click on a selection of browser to URL is displayed.

    I've defined and confirmed that Firefox is my default browser. I uninstalled Firefox, restarted, set Edge as default, rebooted, reinstalled Firefox using the option 'Make Firefox the default browser' and rebooted. No matter what the settings are made and Firefox is default, when I click on a URL link, I get a dialog box "How do you want to open this file", Firefox is highlighted, I click on the check box always 'use this app' and click OK. Firefox opens and displays the page. Thereafter, whenever I click on a URL link I get the pop up and choose Firefox. It doesn't matter if a Firefox session is active or Firefox is closed. What I am doing wrong?

    This was a problem when you try to set one browser by default other than IE (now Edge) on Windows. Firefox has had the most problems over the years, trying to get himself defined as default browser. I can't tell if Chrome has had the same problem either. But I feel that they have had a hard time with her also.

    In the interest to see what works and what does not work, could you not install the Chrome browser and by setting the default value to see if it does indeed remain the browser by default when you click on any url? Please test the links of the opening a few times before you say that it works without problem.

    I'll be tracking of any workaround to set Firefox as the default browser in the meantime. But, be aware that Microsoft is the enemy here. As they do on board the default browser at any price.

  • 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:

  • Display the default value between Dates in guest of dashboard

    OBIEE 11 g

    My users would say the default values shown in my dashboard of the guests. So far, I have created a guest of Dashboard using between operator for dates between CURRENT_DATE - 7 and CURRENT_DATE through SQL results. However, when the dashboard is running the date fields are blank and have not of these dates. Does anyone know how to get these to display. Thanks in advance.

    Instead of current_date-7 you can try with timestampadd(SQL_TSI_DAY,-7,current_date) and
    TIMESTAMPADD(SQL_TSI_DAY,0,CURRENT_DATE)

    It should work.

    In your function mouseDownHandler target you 'e.target.loader', however, e.target is a Loader and Chargers have no property loader.

    var my_thumb:Loader = Loader (e.target.loader);

    Try just "e.target" instead since this should be your code is looking for.

    var my_thumb:Loader = Loader (e.target);

    Although you might find you need to use "e.currentTarget" instead since e.target can point to the content of the loader instead of the charger itself
