Hi Ramsey,

was think in the same lines. Started a test in main() right before calling EXRApplication.main(). Seems to work in dev mode. Will test in prod. Unfortunately (well, no really) I’ll be on vacation so I can only finish my work when I’m back. Will report here.


That method was my entry point into searching for a solution. But this requires to dabble with the Wonder code itself which I dit not want to do, at least not for a start. Might get back to it after my vacation.

Thanks all that responded. Even if someone cannot provide an out-of-the-box solution discussing things here is extremely valuable.

Have you tried scanning for your additional model names in a static{} block in your application class? That should happen very early and seems like it should have enough access to the classpath to find everything. I never really used additional model names and just used the d2w.d2wmodel/user.d2wmodel files.

I found this property “er.directtoweb.ERD2WModel.additionalModelNames” that can be use to load additional D2W model files. I want to make this property dynamic so that its list of model names is built from a directory scan of the resources folder (or a subfolder) and all models found are loaded. This would allow to have models built around some grouping criteria like e.g. per entity without having to manually maintain the list of names in the properties file. I am in a prototype phase where I play extensively with a rather extensive EOModel, adding and removing entities. Such functionality would be great to have.

Anyone done something like this? When during app startup would be a good time to build this list? I think it must be done before D2W is initialized. Probably right before calling might already be too late?

Open for any tip, idea, help, code snippets, whatever.
Thanks a lot
