Rejected promise and then

[mcheshkov]

I expect that if one start a new chain on promise that already received error that error will propagate to that chain, until it meets promise with catchError called, that is AsyncBase with _error handlers.

This

var p = Promise.promise(1);
p.then(function(a){
    trace("then", a);
}).catchError(function(e){
    trace("catchError", e);
});

outputs

then,1

But this

var p = new Promise<Int>();
p.then(function(a){
    trace("then1", a);
}).catchError(function(e){
    trace("catchError1", e);
});
p.reject(2);
p.then(function(a){
    trace("then2", a);
}).catchError(function(e){
    trace("catchError2", e);
});

outputs

catchError1,2

If reject is called after creating of second chain both will catch error.

If one call then on resolved promise immediateLinkUpdate will catch this up and call next.handleResolve There's also isErrored case, but _errored is never updated.

Thanks again, I'll look into it.

Thanks for the heads up. In many cases the errors after the first thrown error were not getting handled appropriately. I added a fix and another test.
