My previous blog had just 2 posts about itself. It was 2007 and since then just didn't feel the urge to blog, or I found some other methods of sharing information.

Last autumn I left company I started with my colleagues, so things changed a bit and now I might have more ideas and information in general to share.

Microsoft Word black box in numbering issue

This is awkward post, primarily to save the solution for future me. I have seen many people mentioning this problem over years and as I've struggled with it several times, I needed to find final and permanent solution.


All editions of Microsoft Word from time to time suffer from bug in numbering. Instead of a number, black box is displayed. Sometimes it happens right after document is opened, sometimes during editing. Probably some internal structure of document gets corrupted, so based on level of corruption, different fixes could help. Many of them are listed at https://answers.microsoft.com/en-us/office/forum/office_2010-word/ms-word-header-styles-are-showing-black-boxes/c427b21c-dcda-46ce-a506-b9a16c9f2f3f


I took different approach. Since docx is just standard zip package with xml files, I decided to try if I can fix it manually. And it worked.

When I extracted the docx, there was file called numbering.xml in word folder. When I examined that file, I found strange section in h…

Using JAX-RS inside NSF

Last week Christian Güdemann published new release of SmartNSF on OpenNTF that contains cool new feature that Christian tweeted before. With new CUSTOM strategy it allows direct execution
of Java code from REST API defined in router configuration. It's even better than it sounds as it initializes facesContext and XPages application if needed, so even access to beans works.

I needed to start to build new REST APIs for few databases, so I decided to test new SmartNSF option and also other available options for REST APIs on Domino (there are several, check references at the end for more info). Since CUSTOM strategy requires dependency on SmatNSF in NSF project and also implementation of CustomRestHandler interface, it'd force me to do more changes in my code that I wanted to. If I need to change my code, why not adjust it for JAX-RS spec anyway.

Existing Domino JAX-RS options had to packaged as plugins, which make it hard to call code that is currently in NSF. I could make it wor…

WSL, HCL Volt and some Docker

My list of new technologies to try was growing fast in past months, but now I finally can try to catch up with all the cool improvements that can be used to enhance my/your dev experience.
Microsoft has enhanced the Windows Subsystem for Linux this year and Docker completely changed the way Docker Desktop for Windows is integrated into the operating system. The most important change for me was that I can finally run Docker Desktop and VMWare Workstation on my machine in parallel. When I was looking for some good use cases to try how it works, HCL Domino was a logical choice. HCL started to even publish official Docker images for every release and some pre-releases are only available as Docker images. I have many test Domino machines running in VMs, but I had no HCL Volt. If you don't know that HCL Volt is - it's a new low-code platform that brings HCL Form Builder experience, now know as HCL Leap, to HCL Domino, which then serves as a data store and application server. When I…
