View the Exhibit
1Z0-419 dumps exhibit
Which three options are true about the scenario in the Exhibit? (Choose three)

  • A. Two separate view object instances allow you, at run time, to maintain two separate current row indicators on each instance respectively, to display separate records at the same time.
  • B. Two separate view object instances defined through the same application module create separate entity object caches, allowing users to modify records in their own independent transactions.
  • C. Two separate view object instances exposed through the application module allow you to apply separate view criteria and bind variable values toshow separate result sets.
  • D. Under the relating AppModuleDataControl in the JDeveloper Data Controls window, each view object instance appears as a separate selectabledata collection
  • E. ADF Faces restricts developers from using the same view object instance across pages, so developers at design time must create multiple separate view object instances.

Answer: ACD

Your page contains the following code that is invoked on an action by the current user;
<af:setPropertyListener from-"#{applicant:surname}" to-'#(...)" type-'action'7>
To receive the value from the to property of the afsetPropertyListener, you create a managed bean as follows
package view;
public class Employee { String lastName;

Answer: C

The current page includes the following entries in its page definition file:
<attnbuteValuesfterBinding="EmployeesView1 Iterator" id="Email">
Programmatically, in a managed bean, you need to read the current EmployeesView's email into a string. You write the following code to do this:
DCBindingContainer be = (DCBindingContamer)BindingContext.getCurrent ().getCurrentBindingsEntry();
XXXXXX emailBinding = <XXXXXX)bc.findCtrlBinding("Emair); String emailValue = emailBinding.getAttribute().get$tring();
What single class must you substitute for XXXXXX in the two locations in the code? (Choose the best answer.)

  • A. CtrlBindmgContext
  • B. JUCtrlActionBinding
  • C. JUCtrlValueBmding
  • D. DCValueBinding E BCValueBinding

Answer: C

  • A. The binding is a Java API for reading and writing data directly between ADF Business Components and ADF Faces.
  • B. There is a one-to-one mapping such that each data control has only one binding.
  • C. There are three types of bindings: method, attribute, and table.
  • D. Expression Language is used to connect a Ul component to a binding.
  • E. Bindings can be created only by dragging and dropping from the Data Controls window.

Answer: D

Which three options are available in the ADF Controller that are not available in the generic JSF 2.0 controller layer? (Choose three.)

  • B. ability to break the page flow of an application into multiple files
  • C. subflows that can be included as regions inside a page
  • D. method calls as part of the definition of a page flow

Answer: ACE

Consider the JSF managed bean code to execute a function in ADF Business Components via an af:button actionListener on a page:
public void doSomethinq(ActionEvent event) {
BindingContainer bindings = BindingContext getCurrent() getCurrentBindingsEntry();
OperationMethod method = bindings.getOperationBinding ("appModuleMethod");
Map paramsMap = method. getParamsMap();
paramsMap put CsomeParameter","someValue"); method.execute();
Which three options must be implemented for this code to work? (Choose three.)

  • A. For the page definition file this code is called from, it must have a <methodAction> binding mapped to the ADF BC data control application module function
  • B. For the page definition file this code is called from, it must have a <parameter> binding mapped to the parameters of the ADF BC data control application module function.
  • C. An appModuleMethod function must exist in the ADF BC application module to call from the <methodAction> binding.
  • D. An appModuleMethod function must be exposed through the client interface editor of the ADF BC application module.

Answer: ABC

Which statement is true about the use of data controls in JSF? (Choose the best answer)
