Just found this while browsing. Domino Formula @Functions. It's more or less a cheat sheet with @-functions sorted in a logical order.
It's actually made by Lotus, for Notes 6.5. You probably need an A3 printer to transfer it to paper.
Share and enjoy!

XPages: Creating a Data Table programmatically on page load
I've finally started working on a proper XPages application at work, so now my inspiration is bubbling.
Todays demo is (hopefully) a precursor to something that will be very useful to you, my readers. I started looking for a way to dynamically creating a Data Table control. Since XPages still is in its infancy, documentation and examples-wise, I had to go look for information on JSF (which XPages is built upon).
I found this great resource. The classes used for UIComponents in XPages have different names than the standard JSF-classes, but the syntax is more or less the same.
To find the XPages equivalent classes, I create the component I want to find the class for. Set an id to it. Then I create a computed field with the value of typeof getComponent( 'componentId' ). This returns the full class name of the component. E.g. the class for DataTable is com.ibm.xsp.component.xp.XspDataTableEx.
In the demo I've made, I create a Data Table control inside an empty Panel component. The panel's data binding is a sessionScope variable. The XPage has a couple of buttons that lets you change the data of the table. The buttons do a partial update on the dynamically created table.

This "technique" can easily be used for programmatically modifying existing Data Tables at runtime as well. Take a look at the code, and get inspired.. :)

CKEditor integration with XPages (32k limited)
I've been asked several times to make an XPages integration with XPages. I finally buckled under the pressure last friday.
Initially I planned on making a full integration (no limits, bound to a NotesRichtextItem). Unfortunately, this is impossible using regular XPages components. I've tried a lot of hacks (rendererType, converting the field in different events, and a lot of other stuff I know nothing about), but so far I've been unable to make the integration work with the native XPages Rich Text editor control.
The last person that requested the integration was "fine" with a 32k limit on the demo, so I've extended the CKEditor Integration demo with a demo of XPages integration (bound to a regular text field).
Read the blog entry on CKEditor integration for prerequisites (CKEditor installed in a certain directory on the server).

Technique: Using a Page as a cross language template/string container
In this demoapp, I use a page as a definition for an XML-representation of a document. It is related to a project at work, where we send XML to a web service. This service is to be called both from the Notes Client, and from an XPage. I could script the XML in both the agent and the XPage, but this could easily develop into a maintenance nightmare.
In the demo, I've used the body of a page as a token string (separated by ¤). The first token is the field-definition. This is to be used in a formula evaluate towards a NotesDocument. The second part is the template itself.
By having the field-definition in the page, you just have to update the page if you want more field values.
I wrote three different script libraries, each having more or less the same functionality. One LotusScript library, one Java (Script) library, and one ServerSide JS library. The libraries contain functionality that extracts the body of the a page based on its name (using a NotesNoteCollection of the pages in the DB).
I also wrote a LS agent, a Java Agent, and a XPage (acting as an agent). Each of them prints XML (based on the template) for the first document in a certain view.
This technique can also be used if you have a big string that is used in code written in multiple languages. If it's Java-code you're writing, and need a big string, this may be an easier way to maintain the string. Another thing that occurs to me is if you generate the same XML/HTML/etc. in multiple databases, you can maintain the String-template in one database, and use Design inheritance to spread it (or get the page from another database using otherDatabase.CreateNoteCollection(false)... )).
As with all techniques, this might not be the right tool for your job. Weigh pros and cons before you decide to use it/not use it.

Avoid using reserved words in JavaScript
A former colleague of mine had an obscure problem with one of his applications. As far as I understood him, there weren't thrown any errors, but the application behaved weirdly in some situations.
Turned out that the cause of the problem was that he used a had a variable called name. name is a reserved word in the JS implementation of the browser (at least in IE).
While I can't remember the last time I stumbled onto this problem, I'd thought I'd share a list of reserved words in JavaScript/the browser implementations of JavaScript, in case any of my readers struggle with this.
To be on the safe side, never call a variable the same as a reserved word.
