how to set tapestry-5.0.13 to development mode

[Argo Vilberg]

tapestry.production-mode A flag (true or false) indicating whether the
application is running in production or in development. The default is true,
which means that runtime exceptions are not reported with full detail (only
the root exception message is displayed, not the entire stack of exceptions,
properties and other information shown in development mode).


And i add this rows to AppModule.java

    public static void contributeApplicationDefaults(
            MappedConfiguration<String, String> configuration)
    {
        configuration.add(SymbolConstants.PRODUCTION_MODE, "false");
    }




This option has no success.



Any ideas?
