Question 1

John has a managed bean which is defined as follows: <faces-config> <managed-bean> <managed-bean-name>distanceConverter</managed-bean-name> <managed-beanclass>bean.MyBean</managed-bean-class> <managed-bean-scope>view</managed-beanscope> </managed-bean> </faces-config> The bean has a property called 'miles' which allows a distance in miles to be entered and converted to kilometers. John wishes to have a user enter a value via an edit box and use the managed bean to convert the value from miles to kilometers. What should the value of the edit box's value attribute be in order to utilize the managed bean?

A. <xp:inputText id="inputText1" value="#{bean.MyBean.setMiles()}"></xp:inputText>

B. <xp:inputText id="inputText1" value="#{view.distanceConverter.miles}"></xp:inputText>

C. <xp:inputText id="inputText1" value="distanceConverter.miles"></xp:inputText>

D. <xp:inputText id="inputText1" value="#{distanceConverter.miles}"></xp:inputText>

Correct Answer: D

Question 2

Jeremy wants all of the dijit.Dialog boxes in his application to call a client side JavaScript function called "validateForm" whenever they are hidden. What is the best solution?

A. Whenever he initializes a new dijit.Dialog, add an onHide event like so:
var dialog = new dijit.Dialog({
onHide: validateForm
}
);

B. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

C. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

D. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

E. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new com.myco.widget.Dialog();

F. Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
using the following code:
/**
*Custom Dojo Control
*/
dojo.provide('com.myco.widget.Dialog');
dojo.require('dijit.Dialog');
(function(){
dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
onHide: validateForm
})
}());
/**
*Initialization code
*/
var dialog = new dijit.Dialog();

G. In the "Close" or "Cancel" button of each dialog add a call to validateForm in the onClick event.

Correct Answer: B,C,D,E

Question 3

Aaron has created an XPages application that has a couple of XPages to surface the same data to two different application roles in two completely different user interfaces. Each role can manipulate parts of the data, but in both cases, the data must adhere to the same business logic and rules. What would be the best way for Aaron to implement the same business logic in each XPage?

A. Create a common Client-Side JavaScript Library for the XPages to share that the user interface can use to execute the business logic

B. Use a series of Custom Controls to hold the business logic and share them amongst the XPages

C. The user interface and the business logic in an XPage can not easily be separated and must be maintained in each XPage

D. Create a common Server-Side JavaScript Library for the XPages to share that the user interface can use to execute the business logic

Correct Answer: D

Question 4

Question 6

Marco has built an XPage that has increased in complexity over time and now contains several hundred lines of XSP markup, with many postback actions that conditionalize the display of the page.

All of the following actions may improve performance EXCEPT which one:

A. Conditionally set the "loaded" property to "true" for controls and data sources that are displayed, and "false" when they are hidden.

B. Reduce the size of the page by splitting it up into several custom controls wherever possible.

C. Use scoped variables to store/retrieve data that will not change between postback requests.

D. Use Partial Refresh to conditionally redraw only those parts of the page impacted by postback actions.

Correct Answer: B

Question 7

Eric is writing an XPages in the Notes Client (XPinC) application and has a data type problem in a Server Side JavaScript function. How can he find out more information about the objects in his code?

A. Set up a new debug configuration in the Java perspective in Domino Designer and then set a breakpoint in the code and step through it to examine the objects

B. Add a Firebug Lite control to his XPage and then set a breakpoint in the code using Firebug in the Notes Client

C. Use print() and _dump statements in his code and look in Help -> Support -> View Trace for the output
