[errai-dev] Errai navigation + templating discussion

[Lincoln Baxter, III]

Maybe we need an @TemplateOverride annotation to alter this behavior?

It wouldn't be hard to do. Though... we may want the ability to do more
global overrides as well... for instance, maybe you want all href
attributes to default to the widget value instead.

Getting the experience of this right might be tricky.

Thoughts?
