Array parameters and callbacks

[ArnoStrouwen]

@mtkmodel DECAY begin
    @parameters begin
        unrelated[1:2] = zeros(2)
        k = 0.0
    end
    @variables begin
        x(t) = 10.0
    end
    @equations begin
        D(x) ~ -k*x
    end
    @discrete_events begin
        (t == 1.0) => [k~1.0]
    end
end
@mtkbuild decay = DECAY()
prob = ODEProblem(decay, [], (0.0, 10.0), [])
sol = solve(prob, Tsit5(),tstops=[1.0])

julia> sol = solve(prob, Tsit5(),tstops=[1.0])
ERROR: MethodError: no method matching view(::Float64, ::UnitRange{Int64})
The function `view` exists, but no method is defined for this combination of argument types.

Removing the array works.

Please reopen, this was not actually fixed for me:

(TESTER) pkg> st ModelingToolkit
Status `C:\Users\arno\Desktop\TESTER\Project.toml`

Closest candidates are:

Could you share the full status and status -m output?

[ArnoStrouwen]

My mistake, I thought this merged before the latest release, but it is not yet included.
Could you do a release, me and @SebastianM-C need this functionality.
