Hello, William.
As far as I understand this class contains a part of SAM (Simplified ABAP Messaging) events names constants. Not all of them. Definitely not.
These SAM messages are represented by class CL_SAM_MESSAGE. And particular 'event name' property is set using its method SET_STRING_PROPERTY (from interface IF_SAM_MESSAGE)
So I'd put a breakpoint in this method and wait for a property with name = 'icwc_eventname'. In value parameter you'll find event's name.
Examples of how to subscribe to these messages can be found in CRMCMP_IC_FRAME in header_jscripts.js file. Function subscribeSAM:
var callback; var eventManager = ICClientEventManager.getInstance( ); callback = processBSPInvoke; eventManager.subscribe( '<%= CL_CRM_IC_CLNT_EVENT_CONST=>COM_SAP_IC_BSPINVOKE%>', callback );
Hope this will help you.
