Robert and Jens first experience and obstacles with the Lively Kernel

Getting started

• How to change stuff in LK and save / publish it
• Setting up an own WebDAV server

User Interface

• we first thought that we would be able to develop Lively from the inside [FIXED :-)]
• missing copy and paste was painful [FIXED]
• working with TextMorph
  • weird keyboard navigation and cursor update [FIXED]
  • Alt-P only evaluates selection and not the line [FIXED]
  • Alt-D replaced the selection [FIXED]

Work cycle

• finding syntax errors was sometimes hard, because of the long edit run loop, when working with the js files directly
• finding runtime errors in debugging and testing was problematic,
  • using the stack tracer wasn't helpful

Design Patterns / Code

• the use of the "Model Plug View" (MPV) pattern and its use in non-GUI objects, e.g. dealing asynchronously with NetRequests, is not obvious and easy to understand

• Terminology: Widgets, Model, Views, Plugs, Pins, Components
