We could use the variable `[A](t)` built as follows ``` CAsym = Symbol("[","A","]") Aconcen = (@variables t, $CASym(t))[1] ``` I just checked and this works fine in plotting an ODE...

Hmm, I thought this was giving a different appearance of the compiled fonts, but now it seems to be the same. So no problem for Catalyst I guess! I'll leave...

Looks like another instance of https://github.com/JuliaSymbolics/SymbolicUtils.jl/issues/434

@shashi this one is going to cause (or perhaps is causing) issues for SBMLToolkit, Catalyst and ModelingToolkit. Is there a workaround one can use to avoid it till it gets...

@TorkelE looks to me like there have been some changes to `build_function` in Symbolics.jl that broke tracing. You might open an issue there about the problem you are having and...

Try `integrator.u.u`. For `VariableRateJump`s we rewrap your `u` in an `ExtendedJumpArray` within the integrator (see [here](https://github.com/SciML/DiffEqJump.jl/blob/c66a4d9595813199f0e9e794d2d43880f25759eb/src/extended_jump_array.jl#L1) for the definition of `ExtendedJumpArray`). You also probably need to use: ```julia integrator.u.u .=...

I've updated the `VariableRateJump` doc string and added one for `ExtendedJumpArray`s to provide more info about this going forward. This should be in the next release. I'll leave this issue...

That would be breaking though right, since `integrator.u.u` would no longer work if we set `integrator.u` to return the `ExtendedJumpArray`s `u` field via dispatch? I'd be happy with such a...

Reflecting about it more, I think we should add a `getproperty` dispatch on `DEIntegrator` with `ExtendedJumpArray`s as the `utype`, replacing `integrator.u` with what is currently `integrator.u.u` and adding `integrator.jump_u`. It...
