I'm trying to edit a single field in a row in an original 400 records table(say, name like 'Garcia Eduardo'…suddenly , for some strange reason, that row replaces other 37 exiting rows data! ( I mean, suddenly, I have 37 records for Garcia Eduardo my table has now 437 rows!! but only the first one has edit-delete atributes)..(more over..if I go to mysql and delete * where name like 'garcia eduardo' thos 37 records are erased (also the original one), but now my table has 363 records..meaning I lost 37 REAL records from the original table… I experimented this twice!1 specially when using icons in the bottom of the grid..
