[jboss-jira] [JBoss JIRA] Commented: (JBRULES-3093) Drools Fusion broker example throws stacktraces in drools 5.2.0

[Geoffrey De Smet (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-3093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12610250#comment-12610250 ] 

Geoffrey De Smet commented on JBRULES-3093:
-------------------------------------------

Maybe the inserted SuddenDropEvent in broker.drl is a different class than the SuddenDropEvent matched in position.drl.


There's org.drools.examples.broker.model.SuddenDropEvent, the java file:
{code}
package org.drools.examples.broker.model;

public class SuddenDropEvent {
...
}
{code}

and the broker.drl has this:
{code}
# an event declaration to represent situations
# where a suddent drop happens. In this case we are not
# defining any explicit expiration policy. 
declare SuddenDropEvent
    @role( event )
end
{code}

Similar wierdness for StockTick
