Erel,

Erel,

1. Please don't.

2. If you are not using B4XPages then you should.

3. Not enough information here.

Thank you for that Erel.

Which exposes a huge problem for you when a 'newbie' like me comes on board: There are so many posts with code that YOU now consider defunct and yet, when the current official documentation doesn't deal with all aspects of the 'new' B4X 'standards'.

There is so many examples of code on this site that, therefore, lead people like me down the garden path ultimately to discover it's now a cul-de-sac. It's quite annoying and I'm certain I'm not alone feeling this. Of course, it's not your fault.

I will investigate Pages.
