The flashSession is not available anymore in DI ? Should we add it manually ? It happened suddently - i think after update the 1.3.0 or the incubator.
It's registered in 1.3.0 in Phalcon\DI\FactoryDefault: https://github.com/phalcon/cphalcon/blob/1.3.0/ext/di/factorydefault.c#L248
Thanks. I have no clue what happened, but after i compiled again everything went back to normal.
