Hi,

In the service task the delegate expression is already supported, so there's no reason to not support it in the listeners.
If you create a JIRA issue I'll look into this for the next release.
In the meantime, I don't have a good workaround other than maybe switching to an expression instead of a delegate expression.

Best regards,

From the documentation i gathered that for using spring managed beans as a tasklistener i need to use a delegate expression. Can it work with an expression as well then ?

jira issue created: http://jira.codehaus.org/browse/ACT-807

thanks

Hi,

Thanks for creating the JIRA.
You can use a Spring managed bean in an expression as well.
The difference is that for an expression you have to specify the method you want to invoke, but then it works fine.

Best regards,
