    [ https://issues.jboss.org/browse/RF-10093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12574222#comment-12574222 ] 

Alexander Smirnov commented on RF-10093:
----------------------------------------

Resolved by changing 'fires' attribute syntax:
@JsfComponent(....
    fires={@Event(TestEvent.class), at Event(value=ValueChangeEvent.class,listener=ValueChangeListener.class)},
    
For events from dependent libraries, it's necessary to explicitly define listener interface.
