[ https://jira.jboss.org/jira/browse/WELD-420?page=com.atlassian.jira.plugi... ] Pete Muir commented on WELD-420: -------------------------------- John, can you please attach a simple set of beans to reproduce. BTW this looks like a user error - the call to isEmpty is coming from EL, not Weld. Double check you aren't trying to return a null object from the producer method. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
