DESCRIPTION

Do not abandon all hope, ye who enter here! Your very own Dante and Virgil will take you through a divine comedy of nine circles that show that XPages is more paradise than perdition. We'll show how XPages and related concepts like OSGi plugins make XPages a modern and vibrant development technology for web, mobile and rich client. On the way we'll guide you past some pitfalls to avoid becoming one of the lost souls. When we re-emerge, you'll see the sky's the limit with star-studded opportunities. (Presented at IBM Connect 2014)

Hybrid “Limbo” Applications

Add XPages into traditional Domino web applications

Use existing Domino databases as data source and new

XPages database for user interface

Add mobile interface

Add XPages for sidebar

Page 8: BP204 It's Not Infernal: Dante's Nine Circles of XPages Heaven

SSJS – The “Limbo” Language

Server-side JavaScript leverages pre-existing knowledge

– JavaScript syntax

• NotesDocument.getUniversalID()

• @DbLookup(@DbName(),“myViewName”,2,

“[FAILSILENT]”)

– Domino objects use LotusScript names

– Many Formula Language @Functions supported

• Kathy Brown has blogged which ones are not

• http://www.runningnotes.net/index.php/2010/03/25/list-

of-formula-not-supported-in-xpages/

“Limbo” Property Values

Custom Language

<xp:text

value= “Database title is #{database.title}, database path

is #{javascript: @Subset(@DbName(), -1);}”>

</xp:text>

Page 11: BP204 It's Not Infernal: Dante's Nine Circles of XPages Heaven

Converting LS to SSJS

Replace “Dim” with “var”

Replace “ As ” with “:”

Add “;”

Remember methods etc are case sensitive and need ()

GetAllDocumentsByKey – need to pass key as Vector

Full syntax required for interacting with Notes Items

RECYCLE!

You want them to want your app

xsp.persistence.viewstate=fulltree

– Default option, whole component tree persisted

xsp.persistence.viewstate=nostate

– No component tree stored, similar to

xsp.session.transient=true

xsp.persistence.viewstate=delta

– Valid if pages stored in memory

– Only stores changes since page loaded

28

Page 29: BP204 It's Not Infernal: Dante's Nine Circles of XPages Heaven

Page Persistence Mode

xsp.persistence.viewstate=deltaex

– Valid if multiple pages stored in memory

– Stores full component tree for current page, deltas for

others

Viewstate property on XPage allows developer to define at

page level

xsp.session.transient

xsp.session.transient=“false” sets XPage stateless

– Default VALUES overridden between requests

– Default STATES not overridden

NOT “Go to next page from current”

– INSTEAD “Go to next page from default”

NOT “Toggle show detail from previous state”

– INSTEAD “Toggle show detail from default”

Partial page refreshes

Client-side processing

– Dojo JavaScript framework (included with XPages)

– jQuery JavaScript framework (easily added)

– Other JavaScript frameworks or custom scripts

Server-side processing

– XAgent (XPage of just code with UI redirect)

– Java (design element or WebContent\WEB-INF\src)

32

Page 33: BP204 It's Not Infernal: Dante's Nine Circles of XPages Heaven

Meet the Users’ Expectations

It’s a “mad mad mad mad world”

– Devices

– Locations

– Connectivity

Responsive design options:

Java

“IBM always wanted us to use Java” – NO!

36

Page 37: BP204 It's Not Infernal: Dante's Nine Circles of XPages Heaven

Why?

#{javascript:…} means parse this string using SSJS rules

Pass commands to VariableResolver

Look for corresponding variable name

Map to a Java object/method

So why not go straight to the source?

Themes

Themes can force controls to behave consistently

But some elements cannot be manipulated easily

–EventHandlers don’t have a default stylekit

–They can have a themeId applied though

Themes loaded at end of page rendering

–getStyleKitFamily() to find default theme id

–Or use Mark Leusink’s debug toolbar

SessionScope is fraudulent

– Session only for current application

– Browser session, not user session

We climbed, he first, I following his steps,

Till on our view the beautiful lights of heaven

Dawned through a circular opening in the cave:

Thence issuing we again beheld the stars
