Asynchronous Mail on Grails 2.5.1

[Sheldon du Trevou]

Asynchronous Mail was working well on Grails 2.4.3 and since we have upgraded to Grails 2.5.1 Asynchronous Mail keeps giving an error when trying to send :

Message: Cannot cast object 'grails.plugin.asyncmail.AsynchronousMailMessage(id:206, to:[te...@temp.com], subject:Registration Activation, status:CREATED)' with class 'grails.plugin.asyncmail.AsynchronousMailMessage' to class 'org.springframework.mail.MailMessage'

Any ideas would be much appreciated.

AsynchronusMailMessage isn't a MailMessage

https://github.com/kefirfromperm/grails-asynchronous-mail/blob/master/grails-app/domain/grails/plugin/asyncmail/AsynchronousMailMessage.groovy

Can you share the stacktrace or what is attempting to cast the AsynchronusMailMessage to a MailMessage?

Please could somebody help out here I really need to get this working or need to implement an alternative as this is a long term project that needs to go live in a month and would prefer to use Grails 2.5.1.

Thanks in advance.

I'm using asynchronous-mail-1.2 (with mail-1.0.7) with Grails 2.5.1, works fine for me.

[Raviteja Lokineni]

The problem seems to be with the return type.

MailMessage send(AsynchronousMailMessage message).

Looks like it should have been AsynchronousMailMessage instead of MailMessage.

Raviteja,

The code he pasted was from the asynchronous-mail plugin: 

https://github.com/kefirfromperm/grails-asynchronous-mail/blob/1.0.x/grails-app/services/grails/plugin/asyncmail/AsynchronousMailSendService.groovy

He would have to fork the plugin or override that service to re implement that functionality.

Sheldon, 

What version of asynchronus-mail are you using? 

Have you guys overridden the nonAsynchronousMailService bean? The plugin defines that bean as a grails.plugin.mail.MailService.

The MailService should return a MailMessage.  

If you can reproduce this locally, then try to debug and see what the actual bean is, and what is returning the AsynchronousMailMessage instead of a MailMessage.

If you can boil this down to a reproducible example that would be helpful.

For anybody else having this issue I changed the option in the config file to false from true :

asynchronous.mail.override=false

Once I made it false it worked because it was not overriding the standard mailService.
