Generalize composite browser/edit screen code through a delegate (gist attached)

Ideas
#1

Hi
I was tired of the boilerplate code that is generated for each composite lookup/edit screen by CUBA studio, so I wrote a simple delegate class that generalizes that code.

I suggest implementing the same or similar solution in next CUBA version, to keep the controller smaller and free of repetitive code.

Thanks,

Hi Paolo,

Thank you for the contribution. We’ll consider including it to the platform in one of the next releases.

Thanks for feedback Konstantin.

Meanwhile, I updated the gist adding support for not auto commit screens (reloading on item change occurs only if the entity is not new/modified), and adding an

AfterInitEditComponents

handler to handle custom UI modifications after the edit state changes.

Bye
Paolo
