| Re: [dali-dev] Listening for Entity Generation operations |

Hi Karen, Is the entire Entity Generation wizard run in a WorkspaceJob, or just the EntityGeneration operition? Basically we want to run the EntityGeneration wizard and operation atomically. Is this how it works currently? So if we launch the Dali wizard; when would we launch our Job (which would essentially be emulating a join()..)? Are we able to do this in a postOperation after the EntityGeneration operation runs? Using a Job in this fashion seems a bit hacky; is there some way we could instead pass our own ProgressMonitor to the operation or something along those lines instead? I'm wondering if always running the Entity Generation in the background could be problematic. It is probably fine in the current use-case scenarios, but could fail in cases like ours where we need to generate an entity before proceeding, or maybe you wanted to perform refactoring to make a composite key out of an entity (which would create the separate EmbeddableID class, which you would probably want to show in the model immediately). Could there be some way to programatically set a switch to have the operation run in the background or foreground? This seems to be a common pattern for these types of generation.

The Job has the IProject as a scheduling rule since anything in the project can change. You could set up a Job as well for the population of your table that also has a scheduling rule of IProject. Then your Job will not run until our entity generation Job has completed. Hope this helps. Karen Christopher Jaun wrote:Hello, Is there a way I can listen for newly generated entities? I see as a result of this change (https://bugs.eclipse.org/bugs/show_bug.cgi?id=181816) in the maintenance stream that entities are now generated in the background when created with your wizard. I have a wizard containing a button that allows a user to launch your entity wizard and when that returns I populate a table with the newly created entities. Now that these are being generated in the background I need a way to know when all the entity generation operations are complete or at least be notified every time a new entity is created so I can add it to my table. Is there a way to do this?
