Hi, i started to examine Basic4android 2 days ago. I liked it, beacuse i could do many things in hours instead of weeks with ST2. Now i want to migrate one of my app to b4a. I attached a picture about screen flow instead of writing many words. There must be a tabhost with 3 tabs, and a listview on every tab. When i clicked an item on List 1 for example, it must be pass a parameter and populate another list (List 1-2) depend on the clicked item value of List 1. Then if i click an item on List 1-2, it must bring the detail screen about clicked item on List 1-2. And it's not finished yet, whenever it's possible i should be able to go bac tot the previous screen/list with a back button (on the left top). How can i do this? I managed to populate listviews on tap pages, but how can i populate a secondary list depending on the primary list and can i put two or more listviews one on a tab page in a tabhost?
