Opening a SDK file from Console REPL shows an error of SerialVersionUID #1135

Closed fdodino closed 7 years ago

fdodino commented 7 years ago

This program

class Malita {
    var noInicializada
    method falla() {
        return noInicializada + 3
    }
    method fallaDeNuevo() {
        return 1 / 0
    }
}

When you send in REPL this message

mala.fallaDeNuevo()

and try to open "/" method it opens ok but shows this error:

An error has occurred. See error log for more details.

Oh , apparently problem is in Static Diagram Configuration!

And it fails because I had a previous configuration file for lang.wlk, shared by all projects.

Solved deleting old file. It should not appear again.
