LotusScript Data Structures Basics
By Andre Guirard | 12/8/22 6:39 AM | Development - Notes / Domino | Added by Roberto Boccadoro
What are these data structures of which you speak?
In computer science, the term “data structure” refers to a way of organizing data into an arrangement you can navigate in specific ways, depending on the needs of your application.
There are LotusScript implementations of the basic data structures in the LotusScript Gold Collection project on openntf.org. You can just take those and use them. But as noted above, often you need to modify the “classic” data structures for your specific requirements, or even create entirely new, specialized stuff. So I want to discuss the basic principles.
LotusScript Variants: EMPTY, NULL, Nothing 
By Paul Withers | 12/7/22 2:07 AM | Development - Notes / Domino | Added by Roberto Boccadoro
One of the great things about working on VoltScript with our team are the regular discussions about the inner workings of the language. Of course it’s also nice how easy it is to write and run a test script with the language, to quickly test various scenarios. Recently, because of two separate initiatives we’ve been working on, the topic of conversation has been Variants, and the potential values that denote a variant without a value.
XPages class-loader memory leak
By Martin Pradny | 12/6/22 11:51 AM | Development - Notes / Domino | Added by Oliver Busse
We have recently experienced OutOfMemory crashes of XPages app server. The server was recently upgraded to 12.0.1FP1, but we were getting some panic crashes in HTTP even before the upgrade (it was 9.0.1FP10). Our hopes were that the upgrade would stabilize the server, but it's not the case. At least now I start to see what's the problem.
HCL Domino Christmas Calendar App stimulates festive mood at the office
By Soehnke Grams | 12/5/22 11:21 AM | Development - Notes / Domino | Added by Oliver Busse
It is that time of the year again. December has arrived and, with it, the Christmas countdown has started. Much has changed in the world in the last years but some things stay the same. For the CEIR team at the University of Koblenz, the Domino Christmas Calendar App makes sure that the festive season is not forgotten.
The forgotten logical operators
By Andre Guirard | 12/5/22 3:08 AM | Development - Notes / Domino | Added by Roberto Boccadoro
Here’s something I notice in a lot of other people’s code I look at, which has always bothered me. This isn’t language-specific — I see it everywhere.
Programmers create logical expressions with the boolean operators And, Or, and Not. It seems to require a sort of sideways view of things to apply the additional operators that work with boolean values, Eqv and Xor (or to use their non-bitwise counterparts which more people might recognize offhand, = and != (<> in LotusScript).
Overhead of error trapping in LotusScript
By Andre Guirard | 12/1/22 6:22 AM | Development - Notes / Domino | Added by Roberto Boccadoro
Having a little fun with the performance monitoring code from a previous post. Okay I have a warped idea of fun.
I’m always interested in performance, so I decided to analyze the overhead of using an error trap (On Error statement) to handle edge cases as opposed to an “if” statement or other branch.
OpenNTF and Community Updates For Notes/Domino 12.0.2
By OpenNTF | 11/28/22 10:52 AM | Development - Notes / Domino | Added by Oliver Busse
A few weeks ago, HCL released Notes and Domino 12.0.2, bringing with them a number of good features for users, developers, and administrators. To go along with these changes, the community at OpenNTF released new versions of several projects within a few days.
Setting up an environment to develop OSGi plugins for HCL Domino – 2022 edition
By Mark Leusink | 11/27/22 2:51 PM | Development - Notes / Domino | Added by Oliver Busse
While testing the v12 version of the org.openntf.domino library I found a bug that stopped me from deploying it to v12.0.x Domino servers. I found out what the cause for the issue was, so I decided to take a shot at fixing it myself. There was just one problem: I didn’t have a development setup for OSGi plugins anymore. Online I could find most of the steps involved, but the guides could use an update here and there.
String Functions Performance Considerations
By Andre Guirard | 11/25/22 12:20 PM | Development - Notes / Domino | Added by Roberto Boccadoro
I’ve been doing some tests and I see Instr$ in LotusScript is still a lot slower when you start searching in the middle of the string. I wrote an SPR about this sometime back.
The same is true of Mid$ – I wrote a timing test that uses Mid$ to get the 1st character of a string as opposed to the 27000th. The latter takes much longer, and I don’t understand why. According to the help docs it’s two bytes per character, so it should be trivial to determine the location of a character from its number position.
XPages Jakarta EE 2.9.0 and Next Steps
By Jesse Gallagher | 11/22/22 4:54 PM | Development - Notes / Domino | Added by Oliver Busse
Keeping with my productive week off, today I release version 2.9.0 of the XPages Jakarta EE Support project. Similar to the previous release, this one contains new features primarily related to Jakarta NoSQL, but also has some improvements for JSF and a bunch of bug fixes and compatibility improvements.
More Open-Source Updates for Notes/Domino 12.0.2
By Jesse Gallagher | 11/21/22 12:39 PM | Development - Notes / Domino | Added by Roberto Boccadoro
The other day, I talked about some changes/workarounds for Notes/Domino 12.0.2. Today, I made a few updates to some of the open-source projects I maintain, including another update to the generate-domino-update-site Maven plugin.
Domino Designer 12.0.2 – Object and Agent list is empty
By Ulrich Krause | 11/21/22 2:04 AM | Development - Notes / Domino | Added by Roberto Boccadoro
The issue applies to the 32 and 64 bit of the Domino Designer 12.0.2. It occurs in Forms, Views and Folders.
Also, the issue only occurs when you open an application in Designer from the Notes workspace.
HCL Domino 12.0.2, Engage 2022 and HCL Factory tour Milan
By Martin Pradny | 11/20/22 7:38 AM | Development - Notes / Domino | Added by Oliver Busse
I haven't published my recap after Engage this year and the recent HCL Factory tour in Milan is a great opportunity to write a summary about what's happening in HCL (mostly Domino) space. It's a mix of news about 12.0.2, future directions, and my impressions, so it can be a bit chaotic, but I got the impression that many people see it similarly.
Configure Eclipse 4.6.x with HCL Notes 12.0.1 FP1
By Karsten Lehmann | 11/18/22 4:07 PM | Development - Notes / Domino | Added by Oliver Busse
Once again I had to ask HCL development for setup instructions how to launch the HCL Notes Standard Client from an Eclipse IDE, this time for Notes 12.0.1 FP1.
The instructions I had gotten earlier for Notes 10 have not changed much (I think there's one additional VM argument at the end of the list), but enough so that they did not work anymore.
New release of Open Eclipse Update Site to fix issues with Win/64 Notes Client 12.0.2
By Karsten Lehmann | 11/18/22 5:13 AM | Development - Notes / Domino | Added by Roberto Boccadoro
As Jesse blogged there are some issues in the new Windows 64 Bit Notes Client 12.0.2 that break the "Import Local Update Site" functionality of the standard Update Site template of Domino.
To fix this and other issues, I just uploaded a new release of the Open Eclipse Update Site on OpenNTF.
Notes/Domino 12.0.2 Fallout
By Jesse Gallagher | 11/18/22 5:12 AM | Development - Notes / Domino | Added by Roberto Boccadoro
Notes and Domino 12.0.2 came out today. Generally, there are some neat features in development and on the server, but there are also a couple things you may run into depending on your workflow and installation type.
Strange XPage, Unexpected runtime error
By Fredrik Norling | 11/18/22 5:11 AM | Development - Notes / Domino | Added by Roberto Boccadoro
I’m going to start a post that I will update regular when I get strange errors that can be hard to find the solution for. Feel free to post a comment or use the contact form to send me your strange errors and a solution or how to debug the problem.
One of the best tools for debugging is to use the Log File reader found on OpenNTF, another good tool also on OpenNTF is the Debug toolbar
But now to the problems and the possible solutions.
