Dali 3.0 Design Meetings

July 13-14th, 2009

Attendees: Shaun, Neil, Karen, Brian, Paul, Tran

Agenda

Open design issues (UI and model)

  • UI and model for JPA 2.0 Id (Paul)
    • Generic JPA is slightly different case than EL
      • Generic - source only case, private in foo; - default to Basic mapping in our UI: M-1 default is error with Id
      • EclipseLink - default 1:1 makes interpretation difficult
      • Is option 2 possible, lets consider further? If not, what are the possible solutions, Option 3 - Lobby spec committee for Derived Id.
      • Day 2 Comments
        • (one option)Make a model that makes sense (where Id is not a first class mapping), then hack the UI as necessary to "simplify" UI. We could probably add an Id mapping into the map as list in a hard-coded, fixed list position (of 2), and then enable/disable this menu item based on the attribute type. The Id selection would only be enabled for primitives.
        • Can @Id and @Basic coexist?
        • 3 Options defined, see picture of white board, pros and cons with each
  • JPA 2.0 meta-model generation (Shaun)
    • Probably want incremental generation (on commits)
    • Talk to Michael O'Brian and Peter about serialization (set up meeting, incremental generation)
    • What happens when the A processor regens, does it clean up.
    • We could tie into refactoring and update queries to point to new metamodel content
    • Generally annotation processor created, but might be advantage to doing this with the Dali model
    • Use EL to generate the source code (send an email to Peter)
  • Legacy Platform support (Neil)
    • Should we support EclipseLink 1.x in Dali 3.0? Yes - keep everything for now
  • Platform version requirements (Paul)
    • Platform UI selection (Neil)
  • Code Topics
    • Conversion to Iterables (Brian)
    • Model events/listeners (Brian)
    • FindBugs(Brian)
    • "2.0" naming and package names for various platforms (Karen)
      • need to define a pattern for all of this
      • New metadata introduced for JPA 2.0 should get the 2_0 label in the class
      • See picture below:

Other Topics

  • XML Translator issues
    • Need to escalate these issues and determine if support is going to be sufficient moving forward
