Getting the value from the subcribed rapid variable

We're programing a server-software in Python that collects data from our YuMi using Web Services. When we subscribe to signals or io everything is working fine, but when we try to subribe to rapid pers varibles we recive an "change event" that the varible is changed but not the value of the variable.

Are we doing somthing wrong or is it not possible to get the value at the same time as the "change event"?
