Blog & Technical Insights

I’ve blogged before about VariableResolvers and the more I dig into them, the more powerful they are. Performance-wise, I’ve already blogged they’re as rapid as you can get, the perfect place for regularly-accessed bits of code. Anyone at UKLUG will have seen that I extended that particular performance table to show that a VariableResolver in […]

Yesterday I totally screwed up my Notes install. Bottom line, it thought it was a multi-user install and no matter what I did, I couldn’t install the full client. There was a very simple cause. The usual one. I didn’t RTFM! We’ve all done it. (Please, just agree to make me feel less stupid.) I […]

If you’ve been developing Domino applications for any length of time, you will be aware of the Design Synopsis. Mainly you’ll be aware of it as a major selling point for third-party tools like those of TeamStudio or Ytria. If you’re new to Domino development with XPages, you’re not missing anything. With Notes 8.5 we […]

Cardiff was the venue for UKLUG this year, two days of all yellow goodness (in every sense!). For the third time I delivered a session digging under the covers of XPages to try to give developers one or more eureka moments. At BLUG I presented on my own but couldn’t fit everything into an hour. […]

Earlier today Julian Buss asked in a blog post about how to get the unid of a selected document in the iNotes List View. Even though I wrote that chapter in the Extension Library book, I was a little baffled myself. Even after I re-read what I’d written, I struggled to work out where I […]

Some time ago Nathan Freeman blogged about making Domino Designer work the way you want, lots of excellent productivity tips for improving performance of Domino Designer. One of these was to turn off Build Automatically. If you ever, ever, for any reason whatsoever, ever, ever, ever open a database that’s on a server in Domino Designer […]

Tonight I came this comment from a developer: Rather than using the DisplayErrors control and showing the error messages, I just want a count.  So I could do something like “You have 4 message(s) on the page” All error messages can be displayed in a Display Errors control but can also be accessed programmatically, via […]

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. The other addition is a Design Definition […]
