I am trying to follow the Errai UI docs and so far it all coming together. But the part about "structured templates" is where m getting lost (its not working for me). So I want my app to have a header (hardly changes), a footer ( will not change) and a content (will change) region, and I think that is what the docs try to explain here : http://goo.gl/q6XrHY
This is what I have done so for : http://goo.gl/MVvMOz
I intend to extend PageLayout to create screens representing different views of the app, all having the same header and footer that the PageLayout template has ?
You're missing an @DataField annotation on the header field in your PageLayout class, so your PageHeader template is not being inserted into the PageLayout.
