JMC-6100 and JMC-6152 Trigger Alerts

Agree with Ken. You select what action you want to take place if the rule is 
triggered. If you want a triggered rule to be displayed in the alert dialog,
then that is the action you should select. If you want something else to 
happen, you select another action. We route errors to the dialog to make them 
discoverable, as there is was no apparent place to place them that would
make people discover them. That does not mean we should always have the 
trigger dialog as a parallel, always on, action for everything.

It may mean that we should log problems somewhere else in the future...

Kind regards,
Marcus

    Thank you Ken,
    
    Yes, JMC-6100 is duplicate of JMC-6152. I have made one of the duplicate.
    Defect is about the Trigger Dialog not promoted even though the intended event had encountered. There will be a One Dialog for one trigger events (which also dumps hprof ). 
    
    Thanks,
