3091	Nonlinear equation system of size 1	Lennart Ochel	Vitalij Ruge	"Nonlinear equation system of size 1 do not show up in the backend as nonlinear equation.

{{{#!mo
model A
  Real x;
equation
  sin(x) = time;
end A;
}}}

Currently, this equation get solved using a nonlinear solver. However, the backenddaeinfo-dump shows the following:
