In a previous post in this series I did a bit of an overview on how MIME works. We also did a little bit about how MIME works in XPages + Domino land. With this knowledge in hand we can now start to analyse the different ways a ‘Pretty words, pictures and attachments’ can be stored in the document.
During development of the ‘XPages Webmail’ interface, I encountered many problems which could only be solved by investigating the MIME content in detail.
To help me do this, I developed a simple control (Mime Inspector) that I could use during debugging, which allowed me to see details of Mime Entities and the relation between them.
To use the MIME Inspector, I just bind it to a “rich text/Mime” field, and then view the output in the XPage. There are 2 control properties that can be control the level of detail
showHeaders – will output the MimeHeader entries of each MimeEntity
showContent – will output the actual content of each MimeEntity
The output starts with a summary of the status of the DominoRichTextItem (which is a wrapper for the RichTextItem. This is less useful but can still be helpful to know in some situations.
Are there Embedded Images that have not been saved yet
are there attachments that are not saved yet
is the wrapped field a MIME field (or otherwise still rich text)
Is the backend item discarded
Then the control will output the visual representation of the Mime Structure.
It does this in a ‘Nested List’ of MIMEEntities so that you can see sibling / parent / child relationship (which is very important when debugging MIME problems)
Each Mime Entity will output:
content type e.g. text/html
mime headers (if set to do so with showHeaders)
content (if set to do so with showContent)
Here is as short demonstration video of the control in action
Installation / usage
You can either install the GregorbyteXspLibrary and use from that, or you can rip out the necessary files and use within an NSF
Embedded Experiences not rendering after IBM Notes FP9
Wed, Sep 27th 2017 5:36a Cameron Gregor Embedded Experiences are no longer rendering after upgrading to FP9.
I suspect it is something to do with the changes to Embedded Browser, either removing it or upgrading it or something else.
I haven’t had a chance to investigate fully. Perhaps there may be a workaround, or perhaps this is specific to the way we are using embedded experiences.
We use embedded experiences quite a bit at our company so we have rolled back for now. If I figure anything out I will post an update but just be a
BuildXPages Deployment Automation Tools – v1.0.0
Thu, Sep 21st 2017 12:47p Cameron Gregor After quite a bit of work I have finally published the first release of BuildXPages!
What is BuildXPages?
BuildXPages is a project which is useful if you are interested in Automating tasks that are involved in building XPages.
For example you may be interested in automating some of these tasks:
Building NSFs from an On-Disk Project
Building Plugins and Features
Refreshing NSF Designs
Setting Template Inheritance of NSFs
Start, Stop and Restart Http server
Uploading Plugins to an NSF Update
Generating and Downloading Files Using XPages’ Persistence Service
Wed, Sep 13th 2017 4:42p Cameron Gregor When developing an XPages application you may run into the need to generate files to be downloaded by the user.
Generating a PDF Report
Exporting Data to Excel Spreadsheet
Creating a Zip File of several attachments
Achieving these tasks usually raises 2 main problems to solve;
What temporary place can I use to generate the files?
How do I allow the user to download the generated files?
For the temporary place problem, some common solution is to either generate the files to some
Bundle Inspector – Diagnosing XPages Plugin Resolution problems
Wed, Aug 2nd 2017 12:26p Cameron Gregor A common task with XPages development is to installing some plugins that provide additional functionality.
If you do any plugin development of your own, you end up doing this task a lot more as you create new plugins, install new versions etc.
It is also common to encounter some problems after installing plugins to your Domino Server! Maybe your expected plugin doesn’t load up at all? maybe the wrong version is loading?
The standard method of diagnosing these problems is to use the OSGi c
Swiper Official Version 2 Release
Fri, Jul 21st 2017 1:52p Cameron Gregor So I have finally posted Swiper version 2 to OpenNTF! (and Github of course)
Swiper OpenNTF Project Page
Swiper Github Releases
The latest version is 2.0.1, and is the same as 2.0.0beta but with a bug fix for the toolbar buttons.
Swiper 2.0.0 beta has been available on the Github project site for a few months, and the core functionality of it works as planned. There was however a bug within the shortcut buttons that I added to the menu bar, and this is a bit of a nasty bug that can cause del
Auto-width Bootstrap Column XPages Controls
Tue, Mar 21st 2017 1:13p Cameron Gregor I’ve been stuck working with OneUI Version 3 for the past couple of years, due to a regretful decision made at the beginning of my major project. OneUI was better than nothing but very frustrating at times.
Finally, I have moved on to my next project and I am now using bootstrap (version 3)
A common task when laying out a page using bootstrap is to divide sections up into rows and columns, and use the appropriate css styles to do so. I’m going to assume you are familiar with bo
Swiper FP8 Version Beta Release
Thu, Mar 16th 2017 12:50p Cameron Gregor Last week I released the ‘alpha’ version of Swiper which was untested on FP8 but presumed to be ok. So far I have only had good reports from the pioneers who have gone ahead and installed FP8 + the alpha version.
I have since managed to ugrade my home office setup to FP8 which unfortunately has broken my ability to launch designer from eclipse but I am seeking some advice on fixing this up.
In the meantime I have to test the slow way of building plugins, import plugins, restart R
Swiper FP8 Integration Rollout
Wed, Mar 8th 2017 12:43p Cameron Gregor Notes Domino 9.0.1 FP8 is finally here and as far as I know (I have yet to download it) it includes the necessary changes which will allow Swiper to swipe whatever it wants, whenever it wants, which is good news for people who don’t like to have ‘Build Automatically’ turned on.
Plan of Attack for release of Swiper version 2.0.0
So, I haven’t actually downloaded FP8 yet, so I can’t say for sure that the updated version works perfectly. Here is a bit of backgrou
Markdown XPages UIControl
Sun, Mar 5th 2017 11:44a Cameron Gregor Often when I’m designing an xpage, there might be a section of the page in which I want to explain some instructions to the user. Some options here are to:
write the Instructions using html and embed directly in the xpage markup
write the Instructions directly in the design pane and format using designer’s ui e.g. bold, color, size etc
use some native xpage controls to achieve the desired result.
Write the instructions in a richtext field on a notes document that is loaded to dis
TextDiff XPages control – For visual comparison of text
Tue, Feb 28th 2017 12:00p Cameron Gregor A few years back I stumbled across Google’s diff-match-patch project which provides some handy algorithms for text manipulation. At the time of discovery I was doing ‘classic’ notes development. Although I probably could have implemented something that worked in lotuscript with RichText or Mime, it wasn’t a priority at the time and I never bothered.
Since then, I have been doing mainly XPages, and now that I have been also doing a bit of XPages Control development. I was
