Forum OpenACS Development: Re: Mobile Theme?
This means you need to write code to handle this. Each application is going to be different, so it is best to customize this to your specific application.
I have been experimenting with Jquery Mobile for specific forms and interfaces that are required to be used on a mobile phone and it really does give you some good user experience with little effort on the front end. OpenACS provides a great resource for the back end development.
If you go this way you might need Json-procs.tcl from CVS HEAD.
