[weld-issues] [JBoss JIRA] Updated: (WELD-454) Observer resolution (event qualifier handling) not in-line with spec

[ https://jira.jboss.org/jira/browse/WELD-454?page=com.atlassian.jira.plugi... ] Matthieu Chase Heimer updated WELD-454: --------------------------------------- Affects Version/s: 1.0.1.Final Description: Page 71 of the spec states: An event is delivered to an observer method if the observer method has *ALL* the event qualifiers. (emphasis mine). The behavior of Weld is if all method qualifiers are present on the event then the method will receive the event. //event injection point @Inject @Q1 @Q2 Event<Color> colorEvent; //fire event colorEvent.fire(Color.BLUE); //All events have both a Q1 and Q2 qualifier //only the last method should be called but all four methods are called public class ColorChangeConsumer { public void onAnyColorChange(@Observes Color color) {} public void onQ1ColorChange(@Observes @Q1 Color color) {} public void onQ2ColorChange(@Observes @Q2 Color color) {} public void onQ1QQ2ColorChange(@Observes @Q1 @Q2 Color color) {} } This behavior is also seen when using Event.select as seen in the docs: http://docs.jboss.org/weld/reference/1.0.1-Final/en-US/html_single/#d0e4194 was: Page 71 of the spec states: An event is delivered to an observer method if the observer method has *ALL* the event qualifiers. (emphasis mine). The behavior of Weld is if *any* matching (including none) qualifiers are present on the method then the method will receive the event. //event injection point @Inject @Q1 @Q2 Event<Color> colorEvent; //fire event colorEvent.fire(Color.BLUE); //All events have both a Q1 and Q2 qualifier //only the last method should be called but all four methods are called public class ColorChangeConsumer { public void onAnyColorChange(@Observes Color color) {} public void onQ1ColorChange(@Observes @Q1 Color color) {} public void onQ2ColorChange(@Observes @Q2 Color color) {} public void onQ1QQ2ColorChange(@Observes @Q1 @Q2 Color color) {} } This behavior is also seen when using Event.select as seen in the docs: http://docs.jboss.org/weld/reference/1.0.1-Final/en-US/html_single/#d0e4194 Clarified my wording on the current behavior of Weld.
