Hello!
I have problem with NPE in beforeDelete event handler. BeforeDelete is created by AST transformation. It was tested in simple scaffolding controller. In integration tests there is no such error, only in live env with mysql db. Field "biImage" in container object is created by AST transformation too. Saving and updating of Foo object is working well - just this delete action is problematic.
My stacktrace:

Code:
class DeleteDbImageCommand {
static public void execute(DBImageContainer container){
Image.withNewSession {
new DbContainerWorker(container:container).delete()
}
}
}
-------------------------------
class DbContainerWorker extends ContainerWorker {
boolean hasImage() {
return (container.biImage != null
&& !container.biImage.isEmpty()) <== NPE is throw here
}
void delete() {
if (!hasImage()){
return
}
container.biImage.collect {it.value}.each {it.delete()}
container.biImage = null
}
SaveCommand getSaveCommand(String size) {
return new SaveToDbCommand(container, size)
}
}
-------------------------------
class Foo {
Map biImage
def beforeDelete() {
DeleteDbImageCommand.execute(this)
}
}
Locked
