problems with variable set as constant in equation library example "de Broglie wave"

[prismv]

version: 0.9.0

The "de Broglie wave" equations contain variable m_kg that is set to m=Ⓒme in doc example. Root is solved without problems, but solving for m gives error "SolvingMenuSolve error: Bad argument type". Furthermore change of m with e.g. me*2 results in m='me*2' kg, which would lead to an solver error.

Hi @prismv, thanks for the report. I can't reproduce on 0.9.2. Could you please either give me an exact sequence of keys that leads to the problem, or alternatively close the issue if it's indeed fixed?

No, it's not fixed in 0.9.2 Why should it be fixed?

How to reproduce:

1. Populate variables by selecting example from documentation ⇒ Root(...) sets i.a. m=Ⓒme
2. Enter then Solve menu with this equation system, e.g. right shift F5 'de Broglie wave' equation menu entry.
3. Solve all missing variables λ, K, v
4. now solve for m
   ⇒ SolvingMenuSolveError
5. now assign result of Ⓒme 2 x to mass m
   ⇒ solve for any variable related to m will not work anymore because of a unit problem with m='me*2' kg
6. m cannot be properly set back to m=Ⓒme by Solve menu actions, only by repetition of the Root example from the documentation.
