[JPR] Hi Guys,
The code regarding a way to display/edit an object has been put into a component. This component is supplied as a part of the World Tour Training, (obviously with the source) and all explanations are given, with the How to use it during the 1st day, and How to understand it during the 2nd day. Those who have been attending WT in East USA will find it in the USB keys they have got during he meetings. And those who will attend in Denver, Long Beach and San José will get it the same way. The actual use of it is just to add some flexibility to the data structure by adding a user-customizable field to some tables. Now the arising next question will probably be: Why isn't it in 4D already? Many possible answers, but the most obvious are: - Lack of time - Objects are just in the beginning phase in V16, so probably more to come - Anyway, the answer is not obvious, and this is why it's important to get the proper explanations during the trainings...
