Description

Hello,

Because of the defered initialization of _dynamic in JSignal1, the createCall method does not return an accured result if no listener has been added yet.

itemSelected=new JSignal1(this,"thumbnailClicked"){};

String call="function(){"+itemSelected.createCall(""3)"}";

// call="function(){}"

itemSelected.addListener(this, listener);

call="function(){"+itemSelected.createCall(""3)"}";

// call=\"function(){Wt.emit('o129','thumbnailClicked',0);}

Kind regards,

Thim.

Hey Thim,

This actually a gotcha that also applies to Wt. The only solution possible would be to force the signal to be connected if createCall() is called. In fact, we could do this without actually exposing it, to keep the current effect of being able to use JSignals for pure client-side connections.

Pieter, this should be fix by not relying on 'isExposedSignal()' in the createUserEventCall(), both in Wt and JWt.

Regards,

koen
