A little over two years ago I blogged about the different languages available in XPages, namely Expression Language, Server-Side JavaScript and Custom. I explained what Custom was and how it could be used. Bearing in mind that XPages are compiled down to Java code, with each control being a class, it makes sense that the

I’ve just published a new release of the Mobile Value Picker on OpenNTF. The main reason for the new release is to force resetContent=”false” on the Cancel button on the mobilePicker Custom Control, to ensure content is not lost in a new document when using the SSJS approach.

One of the first things I do when I install Domino Designer is disable Build Automatically. If you’re not using XPages – or, more importantly, if you’re not working on applications that use XPages – it’s not an issue. However, if you’re working on XPages and either working in a team or may open a database

During Lotusphere 2011 Philippe Riand posted a now infamous tweet asking for members of the YellowVerse interested in writing an XPages book following up on the hugely successful Mastering XPages. It’s been a long time in the making, but now XPages Extension Library has been published, written by myself, Paul Hannan, Declan Lynch, Jeremy Hodge

I started off this tutorial series on mobile value picker with a discussion about some key differences between desktop browser development and mobile browser development. One of the key differentiators I discussed was connectivity. That was why this series has so far focussed on an approach that predominantly used Client-Side JavaScript and avoided interaction with
