Hi,
a workaround would be to
- loop over the complex table and copy the entries in a "temporary" object collection
- add a list tile view to your details screen on the temporary collection
- enable single click action on the tile and add a single click action that will "mark" the tile (set/reset a boolean in the temporary collection object behind the tile)
- add, e.g., an embedded image to the tile that will be visible only if the tile is marked (to give visual feedback that the tile has been actually marked)
Hope this is relevant to your problem.
Regards, Daniel
