Before the ace editor was split so that it can be used in the backend
and the frontend, the displayError function finished by:
website.error(a, b);
As website.error cannot be used in the backend, the method was changed
to return the error and the extensions of the method were in charge
of displaying it. Unfortunatly this return was done like this:
return a, b;
which is not valid javascript.
Now the method return an object with a "title" and a "message" value
instead of wrongly returning two values.
Note: this fix relies on another fix which will be forward-ported from
saas-11.
