MemDataset not throwing exception for faRequired lazarus / 16-Databases ---------------------------------------------------------------------- Donoss · 2016-05-13 16:46 Hi, I'musing Laz 1.6 on OSX and Windows, I'm using a MemDataset and have set a TFieldDef attribute of faRequired, when I post the record with an empty field it doesn't raise the exception. Has anyone else experienced this and over come ? Your help will be really appreciated. Many thanks Andy ---------------------------------------------------------------------- LacaK · 2016-05-16 05:14 In FPC 3.0 it should work. Can you provide code sample which demonstrates error ?
