tested in 2.8.2 still got the problem, about compute field during updates, although the update is not related with the compute field. e.g. update the status field on rent table, when i insert the revert / compensation table using after insert callback. yet the compute i use is for total_price field on rent table.
how can i achieve it? or is this issue is not resolve yet? thanks and best regards, stifan On Saturday, May 26, 2012 9:27:54 PM UTC+7, Massimo Di Pierro wrote: > > Can you please open an issue about the compute on update problem?
