Grails 5.0.0.M2: GroovyPageLayoutFinder is not properly inititialized during BootStrap #53

davidkron · 2020-06-02T12:43:27Z

The GroovyPageLayoutFinder is not yet fully initialized during the BootStrap sequence. The field viewResolver is still null during BootStrap, which results in the exception below.

I did some debugging and it seems that both GroovyPageLayoutFinder and GrailsApplicationPostProcessor are Spring listeners that handle the ContextRefreshedEvent. Since both have no order specified, the default order is applied and it seems that GrailsApplicationPostProcessor comes before GroovyPageLayoutFinder. This results in the problem of this issue, as the viewResolver is set in the event handler onApplicationEvent.

BootStrap.groovy:

class BootStrap {

    def groovyPageRenderer

    def init = { servletContext ->
        groovyPageRenderer.render(view: '/email/test')
    }

    def destroy = {
    }
}

/grails-app/views/email/test.gsp:

<g:applyLayout name="/email">
</g:applyLayout>
