The dims for an Impulse output are not detected

See project dimensionedImpulse.zip. This has a population which outputs an impulse with a dimension. Try to connect the population "FSI PT" to the neuron population "FSI" and set the weight update component to "ImpulseWeight". The input to the weight update component will show no matches, even though the output of FSI PT is an impulse of dimension uS and the input to the ImpulseWeight is also an impulse of dim uS.

The workaround for now is to take away the dimensions from those impulses, but I think this is a bug.
