JWt

When declaring a custom signal, the WMouseEvent type must be set at the end. Otherwise the first argument will be omitted.

A custom type signal of

JSignal6<WMouseEvent,String,String,String,String,String>

requires a JS call with the event for the first user argument. Otherwise the first argument will be lost (ie 'select-sheet').

var e=event || window.event; Wt.emit(Wt, { name:'optimus-dispatch', eventObject: Wt, event:e}, e, 'select-sheet', 'sheetId1', '', '', '');

However, when inverting the types:

JSignal6<String,String,String,String,String,WMouseEvent>

The required JS call does not need the event argument at all. WMouseEvent is properly populated.

var e=event || window.event; Wt.emit(Wt, { name:'optimus-dispatch', eventObject: Wt, event:e}, 'select-sheet', 'sheetId1', '', '', '', '');
