[Gretl-devel] join to dataset with string-values series

Hi all, I've re-compiled gretl this morning using the latest git master state. A script which worked last Friday does not work anymore when trying to join a numerical time-series to a dataset which comprises both numeric and string-valued series. The error is "Cannot overwrite entire string-valued series". I vaguely remember that in some very recent conversation something on string-valued series was mentioned. Could anybody refresh my mind on this, please? ;-) Best, Artur
