Hi Guys

We are just getting to grips with using JS to call VFP servr side functions and got it to work in desktop preview mode but in Android tablet view mode it didnt work

We are using :

var result = Lianja.evaluate("serverside()");


Is the syntax different if calling from a mobile device?

Thanks in advance?

Make sure your server proc is not reliant on the data session in desktop. In other words it should be stateless and not assume a database and tables are open. That's a common mistake made. Use push/pop datasession.

Run the app in a browser and from the JavaScript condole yiu can test your Lianja.evaluate() calls interactively.

Thanks Barry

Understood about the stateless nature of the mobile UI.

So far these calls just flash up a messagebox so there is no data reliance yet.

Any thoughts?

You cannot "flash up a message box" on the server. You can't use any UI commands in server code.
