Grails version: 3.3.1 Rendering plugin: 2.0.3
To duplicate, create a Grails project with one class called Person with three String attributes: name, surname, emailAddress. At the bottom of the show view I have this:
<g:link class="edit" action="pdfThis" resource="${this.person}">Pdf This</g:link>
The method in the controller is this:
def pdfThis(Long id){
def person = Person.get(id)
if(person){
pdfRenderingService.render(template: "/templates/pdf/person", model: [person: person], controller: "person", response) // this is line 105
}
}
I notice that def pdfRenderingService does not work anymore. One has to have:
grails.plugins.rendering.pdf.PdfRenderingService pdfRenderingService in the controller.
This is the template, called _person.gsp, in views/templates/pdf/

I have no idea what is null and why it is null. Everything I am responsible for is there and is not null.
