Re: [Gretl-devel] weird error with 'omit'

I'm struggling with an error message after trying to do an 'omit' after simple OLS. The message says (re-translated): "Can't do this: some vars in original model have been redefined", and I traced this message back to lib/src/gretl_list.c:2013. There it says "Checks whether any variable in @list has been redefined via gretl's %genr command since a previous model (identified by @ref_id) was estimated." However, my script has the 'omit' right after the 'ols', so how could that happen? Also, changing some options (like --robust in the estimation, or --auto in the omit command) or re-starting gretl sometimes seemed to work in the sense that I got some omit tests, but then it wasn't and still isn't reproducible. I also couldn't get the error with some example dataset, sorry. The sample here is an undated cross-section, coming from "slicing" through a panel by restricting the sample to a single time period.
