How to check the values of the view object?

Hi all

I created a new object view by right-clicking my module of the application. Now when I try to retrieve values

the attributes of the view object, I get null pointer exception. How can I check if the view has

some values inside or not manually by using the select statement? I'm trying to find the view in my database to the database browser

but he was not there. Kindly help me out in the present.

Thank you
Flavian.

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

  • How to check the page dirty with default values existing in viewObject?

    Hi all

    I use JDeveloper 11.1.1.4.

    I have two pages in my application. I am browsing for page2 page1.

    Before opening page 2 I created new line page 2 notice of object using method 'Create Insert()' with some default values by using the ViewRowImpl class.

    My problem is that I have a button to return to Page 2. If I click the back button, then check the Application module is dirty or not.

    But it always shows AM is dirty due to I'm setting some default values in ViewRowImpl. If I avoid the default values in ViewRowImpl then AM dirty check works fine.

    My Question is how to check the AM (or) dirty Page with default values in the object view?

    My bean Codes:

    Links DCBindingContainer = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

    DataControl dc = bindings.findDataControl("AppModuleDataControl");

    ApplicationModuleImpl am = ((ApplicationModuleImpl) dc.getDataProvider ());

    If (am.getDBTransaction (.isDirty (()))

    {

    return "Page is dirty."

    }

    My Jspx Codes:

    < af:commandLink id = "cl6" text = '2 '.
    shortDesc = "Add Row in Page2"
    actionListener = "#{bindings." Action CreateInsert.execute}' = 'Edit' >

    Thank you

  • 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:

    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.
