understanding .spy

[waqas]

Hello,

Thanks for your offer to help.
Yes i will need your help to develop some debugging tool.

I am using .spy to log observable values , when i try following code

Why i am not getting values of my 3rd Observer which is made by "zip" of first two.

Thanks
Best Regards

creates an EventStream that delivers the given series of values (given as array) to the first subscriber

I would take a guess that because your spy is actually an idle subscriber (particularly with a .onValue for each of the streams) - this is the first subscriber. By the time your .zip comes along, and then subscribes - the values fromArray are already gone.
