Setting rate doesn't work for poisson sources after reset

[Anna Bulanova]

I make 3 runs, changing poisson source's firing rate, but all three output spike trains are exactly the same.

import spynnaker8 as p

def print_spikes(trains):
    nseg = len(trains.segments)
    for i in range(nseg):
        trains1 = trains.segments[i].spiketrains
        print "segment ", i, " ", trains1[0]


to_plot_wgts = False

p.setup(1)

simtime = 300

pop_src2 = p.Population(1, p.SpikeSourcePoisson(rate=0), label="drive")
pop_ex = p.Population(1, p.IF_curr_exp(), label="test")

proj2 = p.Projection(pop_src2,  pop_ex,  p.OneToOneConnector(),
               synapse_type=p.StaticSynapse(weight=2.0),  receptor_type='excitatory')

pop_src2.record(['spikes'])
pop_ex.record('spikes')
nseg = 0

pop_src2.set(rate=100)
p.run(simtime)
print_spikes(pop_ex.get_data('spikes'))
p.reset()
pop_src2.set(rate=50)
p.run(simtime)
print_spikes(pop_ex.get_data('spikes'))
p.reset()
pop_src2.set(rate=20)
p.run(simtime)
print_spikes(pop_ex.get_data('spikes'))
p.reset()

p.end()
print "\n job done"
