H, Cesar.

Thanks here also.

I’ve seen the video, but need to find time to install and test it locally. 

Seems interesting for direct generation. 
No example is given for reverse-engineering.

As I see, customizing for Apache Isis would be a matter of defining 
- a custom profile for Apache Isis (perhaps it would be enough with the Java 
one).
- and an Apache-Isis specific Library (for generating the properties, actions, 
etc. with the proper annotations).

It remembers me quite well the Spring Roo customization on SparxSystem’s 
Enterprise Arquitect.

There I implemented also a custom toolbox, in order to avoid to first create 
the attribute and after that assign to the specific library item (instead of 2 
different steps).

Perhaps all that is also possible here.


Thanks,

Oscar
