[Gretl-devel] probable bug with lost panel time

Hi, it looks as if the panel-time information in the current dataset is lost when: 1) a user-written hansl function is executed which internally plays around with and repeatedly resets the sample 2) before calling that function, the current panel dataset is restricted (in the time dimension) Symptom: trying to use $obsdata works before calling the function, but yields an error "won't work with the current periodicity". But $pd and $datatype still work correctly. Workaround: re-issue the setobs command after execution of the hansl function, in my case: "setobs 4 1991:1 --panel-time" Or to formulate my hypothesis differently: it seems that on exit from the function, gretl somehow forgets to reinstate the previous panel time properties when it reconstructs the state of the dataset that prevailed at the time of calling the function. I believe that the problem  didn't show up for me when I was previously working with a dataset which was *not* restricted at the outer level. So the sample restriction appears to play a role. This is with the latest snapshot (Dec 29th). thanks sven
