The broadcast event sends the specified event (message) into the workflow context to pass along to the executing activities.

The typical use of this method is to enable activities that wait for some action to occur before proceeding.

Syntax — broadcastEvent(String contextId, String eventName)

For Example —

//where the current is a task record with a workflow context
var wf = new Workflow().getRunningFlows(current);
while(wf.next()) {
new Workflow().broadcastEvent(wf.sys_id, ‘resume’);
}
