Description Istvan Rath

If an EPackage is resolved through both the EIQGEN file as well as the EPackage Registry (which is a valid case when e.g. Xtext is used, which requires a manual registration of workspace EPackages through a context menu, see Joost van Pinxten's quoted remark below), the IncQuery tooling shows a confusing error message. Even though the error is shown, the system functions correctly.

Joost van Pinxten's remark:
"I remember now that the Xtext MWE2 workflow also requires me to explicitly locate the locations of the genmodels. In order to develop my Xtext grammar and my models in the same workspace I need to use both (i.e. explicit registration of the genmodel and runtime registration of the DSL EPackages)."

I have added this issue as blocked by https://bugs.eclipse.org/bugs/show_bug.cgi?id=398821

Furthermore, IF we can decide that an EPackage in the registry was registered by hand, we can be smarter about what errors/warnings to show.

This is really annoying. The error should be reduced to a warning.

Comment 3 Istvan Rath

I have committed a modification to reduce the error to a warning.

As per http://wiki.eclipse.org/EMFIncQuery/DeveloperMeetingMinutes/Meeting20130521, we agreed on the following action plan:

- EIQGEN will not be modified significantly for 0.7
- Zoli will adjust the tooling to direct the users away from using EIQGEN (by default)
- Zoli will document the proper way of using EIQGEN

Quick links removed to genmodel wizard/genmodel page removed from new project wizard. Postponing documentation to RC.

Added documentation to new wiki page about various resolution mechanisms: http://wiki.eclipse.org/EMFIncQuery/UserDocumentation/QueryLanguage#References_to_Ecore_metamodels

Postponing remaining tasks to the future.

Assigning more complex issues to 0.8-M4. Please discuss if feasible or needs to be pushed to post-0.8.

It would be nice, but I have no time for proper adjustments in the next months. Postponing.

Comment 9 Istvan Rath

2014-04-24 04:32:16 EDT

I'm expecting this to be addressed for 0.9.

Identifying long term goals for 1.0.

Comment 11 Zoltan Ujhelyi

Remaning tasks are only relevant if metamodel is (1) installed and (2) the plugin.xml-based registration does not work.
