Example Application

[graemerocher]

There is no raw method for controllers as far as Im aware

[atasc]

From Grails documentation http://docs.grails.org/latest/guide/single.html

##############################
Raw Output
If you are 100% sure that the value you wish to present on the page has not been received from user input, and you do not wish the value to be encoded then you can use the raw method:

${raw(book.title)}
The 'raw' method is available in tag libraries, controllers and GSP pages.
##############################

In Grails 2.5.4 it works.

[graemerocher]

So it looks like it was optimised to be a method for tag libraries only and not a tag in all versions of 3.x so that documentation is incorrect for all versions of 3.x right now.

I don't know why you would even need it in controllers since there is no automatic escaping in the render method so just using the string without raw would do it.

Fixed in the docs
