I have some problems when using rendering plugin.It always returns me a null pointer exception.I saw severeal similar problems but I didn't find where I'm wrong.
Code of my template : /views/appRetail/_report.gsp
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org /TR/xhtml1/DTD/xhtml1-strict.dtd">

Code of My controller :
class AppRetailController {
def pdfRenderingService
def renderFormPDF() {
def apps = App.findAll()
new File("test.pdf").withOutputStream { outputStream ->
pdfRenderingService.render(template: '/appRetail/report', model: [apps:apps], outputStream)
}
}
}
Here is the stacktrace :
