QUESTION 1
Which statement is false? (Choose the best answer)

A. A panelDashboard has the same rowHeight (or all the rows
B. AFStretchWidth in the style class of a panelGroupLayout causes it to fi II the page horizontally
C. panelGroupLayout cannot have a vertical scroll bar
D. panelBox stretches if placed inside a panelStretchLayout center facet

Answer: C

QUESTION 2
Consider a case where a view does not load with the expected data. Where would you set a breakpoint to debug the issue? (Choose the best answer.)

A. the executable binding for the iterator on the pagedef for the view
B. a router activity that is used to determine where to send the user after selecting a row in the view
C. the partialTriggers property of the data bound component in the view
D. the value binding for the iterator on the pagedef for the view

Answer: D

QUESTION 3
Which three statements are true about declarative features of view objects? (Choose three.)

A. You can use view object bind variables to parameterize a view object where clause with values supplied at run time.
B. By default, a view object instance retrieves all database rows into the view object cache.
C. To implement master-detail behavior between two view object instances, you define an association between those instances.
D. a view accessor defines a validation expression that you apply to a view object attribute.
E. A view object can include attnbutes whose values are based on SQL expressions rather than mapping directly to a database columr
F. A view object definition can include many view criteria but you can choose which view criteria to apply for each view object instance.

Answer: A,C,E

QUESTION 4
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: A,B,C
