Hello [~soledad],

I don't think silencing such template rendering errors with  "∎" is a good 
thing.  If the initial problem is that stacktraces pop up in production, then 
it is a bug and the developer is to blame.  If such mistakes appears frequently 
then this is probably a deeper technology issue meaning that templating in 
OFBiz is prone to error and should be improved or replaced.  If the latter is 
true then we should think how to design a more robust, simpler tool, not how to 
put dust under the carpet.

> Currently when freemarker failed to execute a template, you have on end 
> screen rendered all java stack trace generate.
> I propose to improve this to display the stack trace only when the property 
> widget.verbose is true, no regression during development and when you switch 
> to production site, in general your widget.verbose is false so end user 
> haven't stack trace (that totally unused for them).
