I guess in my case it had to do with JBoss EL Parser...
but.. anyways... I did an workaround that I am not proud of but at least let
me catch the event, I've changed
org.apache.myfaces.trinidad.component.UIXChart.broadcast method and added
setProperty(EVENT_KEY, event);
just before:
broadcastToMethodExpression(event, getChartDrillDownListener());
this way I can specify the listener as:
chartDrillDownListener="#{chart.drillDown(event)}"
For some weird reason when UIXChart tries to get its listener through
getProperty (I guess) JBoss EL Parser does not resolve it to a method unless
it ends with an (). Weirdly enough a4j:commandLink resolves properly its
actionListener property on other form (what makes me think we could lookup
in the same manner on UIXChart).
