Description

List of issues with the developer training guides from #1238 that I was unable to fix myself.

Chapter 5:

• Need to better explain GraphReadMethods/ReadableGraph vs GraphWriteMethods/WritableGraph, how they relate to locking and the importance of .release()/.commit().
• Need to better explain executeNow vs executeLater.
• Recommend making 'Spread Outbreak' a step-by-step tutorial and having students build a selection plugin as an exercise. - This one I was unsure if it'd been done already because I am not familiar with the code

Chapter 6:

• 6.1.2 > We should move all this to the toString() method of Outbreak.

Bugs:
Setting Geo.Country to digraph should auto-complete to country
Duplicate cities in training data are merged, we should add country as a primary key to avoid this

Documentation Additions:
Chapter 4: Controller parameter behaviour (PluginParameterControllers)
Chapter 5: Controlling merging behaviour (GraphElementMerger / GraphAttributeMerger)
Chapter 8: Security & Proxy management
Chapter 9: Graph Renderer Framework
Chapter 9: Arrangement Framework

Other things that could be good to add:
Rendering framework
layer.xml
Rest API
Management of 3rd party libraries
Adding application preference options

Hello @Quasar985, thank you for your interest in our work!
If you have a question about using Constellation then please have a read of our Quick Start Guide.
If you are a developer then it is advised to go through the Developer Training Guide.
Note: We have already migrated to NetBeans 12, however the examples in the training guide still reference NetBeans 8.2. We are working on a new version so just bear that in mind.
PS: I'm just an automated script, not a human being.
