[Seaside] make WAWalkbackErrorHandler

[Esteban Lorenzano]

Hi,

So, I’m in Togo teaching Pharo and Seaside to students, and part of the course is to make a small application (they have 3 days for doing it). The first blocking issue they have is that since default error handler is WAHtmlErrorHandler they are lost each time they made a simple mistake (WAHtmlErrorHandler eats rendering problems, for example… or just shows DNU without saying anything.
And of course showing the students the configuration interfase is overkill :)

Now, since the default registration includes the toolbar, meaning than by default we have a “development app” (A correct approach, IMO), I wonder if we couldn’t put WAWalkbackErrorHandler as default as well? (I remember previous versions of Seaside had it, but it had changed since then).

cheers, 
Esteban
