Subject Re: Dynamically reloading the model on change
Date Mon, 30 May 2016 12:44:20 GMT
I currently use JRebel for class reloading when developing WO. It has a relatively simple plugin
API that can be used to watch changes to Cayenne project files and trigger stuff on file/class
modification. It could replace the ServerRuntime instance, but it would need some way to know
what ServerRuntime instances to replace with a new instance. This could be specified in a
configuration file—or is there some way for me to retrieve all ServerRuntime instances related
to the modified entities?

question is how practical this is, considering you also need to reload Java classes. I guess
also doable if you run in debug mode that does class reloading.
