wakeup from sleep mode with uart interrupt

Hi everyone

I'm trying to put my STM32L1 into sleepmode and wake it up again with an uart interrupt. So I send it to sleep using:

PWR_EnterSleepMode(PWR_Regulator_ON,TRUE)

which works, but now it does not wake up when I send data through the uart. Does anyone know why? Is there some flag I need to set to allow the uart isr to wake my stm up?

Thanks!
