Last week Jesse Gallagher blogged about using enums in a combo box. For those who are not familiar with enums, if you’ve started using Java it’s well worth reviewing the article where I covered them. Thankfully I was involved in a chat around that topic with Jesse and Nathan. I had previously written code to […]

I try to avoid using the word “bug” too freely, because those who live by the word “bug” may die by the word “bug”! After all, we’re software developers whose own software may include bugs. Use the word freely and we can’t complain when others also do. But a little while ago I was battling

Since M3 we’ve had Listeners implemented in the OpenNTF Domino API. Although there’s potential for even greater implementation of listeners through the API, they’re already extremely powerful. Think about triggering specific code whenever a document is saved from XPages. The concept is very powerful and there has been an example in the Demo database for

Most developers (certainly myself!) are lazy. We look to re-use code and write the briefest code we can. Sometimes it backfires! When writing a method, either in Java or LotusScript, we can often pass parameters around with little concern. I came across that some years ago with LotusScript when objects were being changed by a

Two weeks from now I’ll be speaking at Engage.ug, along with a host of illustrious names from IBM and the community. I’ll be speaking with Martin Jinoch about the OpenNTF Domino API. After speaking on the API solo at various user groups and during speedgeeking at IBM Connect, it will be interesting to co-host the

Some time ago Niklas Heidloff blogged about three kinds of XPages developers – those who just use drag and drop with SSJS / JavaScript; those who use Java but only in an NSF; and those who develop with Java outside the NSF. For some time I’ve been doing some development outside the NSF, but after

First of all, I’m not saying back-end developers are real men or are the only ones who have “Curiosity”! But I’ve begun to realise more and more that XPages developers are either back-end or front-end, features or look & feel. In the old days of Notes Client development, the two were so tightly coupled that

Integrating Java into XPages is not particularly challenging, once you are comfortable with SSJS. There are some gotchas around Domino objects (database.getTitle() and other such methods that return primitive values – strings, etc – still return the value even after the object has been recycled!), but those are the kinds of things the OpenNTF Domino

If you’re coming to XPages from traditional Domino development, it’s a bit of a steep learning curve. But once you’ve got comfortable with SSJS and the partial refresh lifecycle, you should be looking to move to Java. Even though the Java compile-time validation is much tighter and avoids a lot of inadvertent errors from SSJS

Recently I’ve been working with the Name Picker where I was using the Name Picker to select values that would then be used for Readers and Authors fields. I noticed that although it picks from address books, the names are stored by default in abbreviated format, e.g. Paul Withers/MyCompany rather than canonical format, e.g. CN=Paul Withers/O=MyCompany. This
