Over the last week I've been rather busy including some XPages functionality in an existing Domino web application, and as an example I wanted to explain why I chose XPages, some steps I took and the ...
SourceTree and Git/Mercurial: Important Information
Fri, Dec 19th 2014 8:09a Paul Withers For anyone who has used the slides from my Show and Tell on source control in January or the subsequent NotesIn9 episode, the recommended Git / Mercurial client was SourceTree. It’s an excellent tool for those who prefer a GUI and runs on Windows and Mac. The advice at the time was to use the embedded Git / Mercurial. For most XPages developers, who were only pushing and retrieving files via SourceTree, that was adequate.
However, overnight I became aware of a security vulnerability with G [read] Keywords: show and tell
Why My XPages Buttons Are Only Ever “Buttons”
Fri, Aug 22nd 2014 8:15a Paul Withers Buttons in XPages are interesting and potentially dangerous elements. They’re dangerous, mainly to less experienced XPages developers, because they have this apparently helpful combo box that immediately attracts the eye for Button type.
Cancel is useful, but to be honest I never set that. All it does, if you look at the source pane, is set immediate=”true”. Based on the level of understanding I’ve got now of tuning events, it makes more sense to set that on the Events [read] Keywords: collaboration
Quick Tip to Quickly Jump To Where You Need to Work
Mon, Aug 18th 2014 6:12a Paul Withers Moment of most celebrated enlightenment usually comes from putting together a frustration with a piece of knowledge gleaned for a completely unrelated reason. A couple of days ago I had such an epiphany.
Often when I’m developing I need to check something somewhere else on the XPage or Custom Control. Or I need to add a custom property to a Custom Control, for which I need to position the cursor on the xp:view element of the Custom Control in order to see the Custom Properties panel. But I [read] Keywords: collaboration
The Perils of getColumnValues().get(0)
Sun, Jul 20th 2014 4:12p Paul Withers Bill F posed a good question on StackOverflow about the issue of object.recycle and when to use it. It’s un understandable question and one I hit years ago after crashing a server looping through 20,000 documents in a search. I raised a PMR, got a response directing me to technotes on recycling in Java. Searching help, wikis and other places gave me no documentation on recycling in SSJS, which gave me reason to believe I was the first to hit the problem in XPages. So I blogged about it at [read] Keywords: agent
XPages Build Project Investigations Improvement
Wed, Jul 9th 2014 7:15a Paul Withers Some time ago I wrote about how you have to build twice if you have Build Automatically switched off, then open an application in Designer and make a change – the first build was incremental.
Just to revisit, I would always recommend having Build Automatically switched off unless you’re in an instance of Designer that can only ever have access to a local Domino server or local applications. Building a database remotely is not quick. Building a database has been known to break it if t [read] Keywords: domino
Triggering an EventHandler from Another Button
Tue, Jul 8th 2014 7:15a Paul Withers Today there was a question on StackOverflow about how to trigger an eventHandler of control A from control B. I knew I’d done it before, but couldn’t remember where and couldn’t find where I’d blogged on it. So here is the way I originally did it and the better way.
The Padawan’s Way
Once you start going to the source pane, you see much more than you do in the Design pane. One of those things you see is that you can click on an xp:eventHandler component and you see [read] Keywords: xpages java
What Happens When An XPage Loads?
Wed, Jul 2nd 2014 4:11p Paul Withers There have been a few questions lately on StackOverflow trying to troubleshoot activity during the initial page load. So I thought I’d write a post to try to clarify the process. This certainly helps me pre-empt some functionality and provides an explanation for some of the questions I’ve seen. Using code from Jesse Gallagher’s XPages Scaffolding in projects has really helped give me this understanding, so I’d like to give Jesse a shoutout for his work.
