Koen, 4D does not handle dot notation (not quite true : see http://doc.4d.com/4Dv16/4D/16/QUERY-BY-ATTRIBUTE.301-3036512.en.html <http://doc.4d.com/4Dv16/4D/16/QUERY-BY-ATTRIBUTE.301-3036512.en.html>) ; I have written a component published on jan 12
This component emulates 4D standard commands for objects such as OB Set or OB Get to add access to properties or sub-objects by path with dot notation. It has been clearly inspired by OBJ_Module of Cannon Smith but differs by : - it emulates standard commands and does not have commands by type - it resolves paths with arrays elements - it gives some advanced controls such as search in an array by the value of a property. It does not intend to replace all functions of OBJ_Module. You can download it here <http://forums.4d.fr/4DBB_Main/x_User/4018/files/18896249.zip>. Method OBJ_Test gives several operational examples ; some functions are not yet implemented. For this thread, I separate setter and getter ; the two commands have same syntax and you can copy the setter, change one letter and have the getter OBJ_Set(MyObject;"MyPath";->MyValue) ... do something OBJ_Get(MyObject;"MyPath";->MyValue) Direct access to the post where you can download the component : http://forums.4d.fr/Post//18896257/1/ <http://forums.4d.fr/Post//18896257/1/> Cannon Smith has also added this feature in its component.
