PreDestroy not called [message #1272155]

Hi,

I've created a the following Xtend-class in my e4 application, that runs in compat mode:

@Creatable
class FileProvider {

	@Inject
	Logger logger

	@Inject
	new() {
	         // CALLED	
	}


	@PostConstruct
	def initialize() {
                // CALLED
	}

	@PreDestroy
	def cleanup() {
		// NOT CALLED
	}

}

I added it via ContextInjectionFactory.make(FileProvider.class, context);. The package javax.annotation (1.1.0) is also specified in the manifest.

Has anyone an idea what might cause this?

Best regards and thanks for any kind of help.
Bastian

Hi Thomas,

not that I'd know... If there isn't any other way to dispose it other than calling context.dispose(), I did not.

Best regards

I have a similar (the same?) problem. My PreDestroy is also not called. I annotated my class in a similar way and used the correct make() call. When calling context.dispose(), the disposal is triggered, but no PreDestroy is called.

Please shed some light in here because I want to use it "the correct way".

EDIT: Turned out that I forgot javax.annotation in the "Imported packages." It works now.

Can you show me your Bean? If you only use postconstruct and constructor
injection you might be running into
