> The idea is to document commands that add new code to existing classes ({{add}} commands). Example, the command to add a [CDI producer|FORGE-2079] or add a [CDI injection point|FORGE-2226]
> Draft notes from #IRC
> gastaldi UIContext.getInitialSelection() should return a UISelection of Resource objects
> gastaldi  Call get() on it and you should have a JavaResource if the command is executed in the context of a java class
> gastaldi  Make it the default value of the targetClass field
> agoncal What does the Callable do in the initializeUI method do then ?
> gastaldi  That should be used when the value changes over the UI interaction
> gastaldi  That is not the case afaik
> gastaldi  Because once you execute the command, the initial selection will not change
