Gradients from an SDE solver with callbacks

I am trying to get gradients of the solution of an SDE where a callback function is used in the solve command. It seems that the forward adjoint method is not compatible with the usage of callbacks as I get "ERROR: type Pairs has no field callback". Or is there a way how to make it work?

Here is a simple example derived from the Lotka-Volterra tutorials

using DifferentialEquations, Flux,  DiffEqFlux
using  DiffEqSensitivity

function dt!(du, u, p, t)
  x, y = u
  α, β, δ, γ = p
  du[1] = dx = α*x - β*x*y
  du[2] = dy = -δ*y + γ*x*y

function dW!(du, u, p, t)
  du[1] = 0.1u[1]
  du[2] = 0.1u[2]

u0 = [1.0,1.0]
tspan = (0.0, 10.0)
p = [2.2, 1.0, 2.0, 0.4]
prob_sde = SDEProblem(dt!, dW!, u0, tspan,p)

condition(u,t,integrator) = integrator.t >9.0 #some condition
function affect!(integrator)
	 println("Callback")  #some callback
cb = DiscreteCallback(condition,affect!,save_positions=(false,false))

function predict_sde(p)
  return Array(solve(prob_sde, EM(),  saveat = 0.1,sensealg = ForwardDiffSensitivity(), dt=0.001, callback=cb))

loss_sde(p)= sum(abs2, x-1 for x in predict_sde(p))

ps = Flux.params(p)
@time gs = gradient(ps) do
end  #ERROR: type Pairs has no field callback

It was a bug. Fixed in and will get released soon.

Thank you!
