Hello
you do not call listeners from javascript.
They are called when the Windchill event you have subscribed to is triggered ...
Some of the events are documented in the API (cf Matthew post above)
But the eaysiest way to find the event to subscribe, is to enable the event logs on MethodServer
set wt.services.verboseEvents=true in wt.properties
Then , do the User action where you want to plugg your listener ... and then get the exact events call hierrarchy and name in the logs ....
regards
