Yeah, this is a know issue with dimensions… will merge with another report (not the same issue on first look, but actually has the same causes). Thanks for the report anyway.

Hmm, no actually, it’s something different here.

First of all, you are controlling dim using it as parameter, this will never work in any case (dependency cycle).

However, there is something else here, rather strange - dimensions.x is always invalid, but dimensions- [x] does work, that’s not normal I think.
