[Antonio Goncalves (JIRA)]

     [ https://issues.jboss.org/browse/FORGE-2233?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Antonio Goncalves updated FORGE-2233:
-------------------------------------
    Description: 
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
