In a Grails app, I am trying to figure out when to use a view and when to use a template for a gsp. Are there any obvious reasons? Or does it just come down to reuse?
Basically Template is a (reusable) part of a View. Useful for splitting View into logical parts and/or for reusing same code from different views.
So, if you're rendering a whole page - use View. If you need just a small part - use Template.
See docs for Views and Templates - http://grails.org/doc/latest/guide/theWebLayer.html#viewsAndTemplates
