Navigation flow when clicking on an item in the list.

[Brian Hayward]

I'd like to have a button that launches another screen.

This screen shows a list of items to select from.

When tapping on an item in the list, it issues a screen return;

Example:

list (item in Items.all())

{

   item(){label(item.name, onclick={handleTap(item);})}

}

function handleTap(it: Item)

{

    // do something with item

    screen return;

}

Unfortunately, you can't put screen return; in that spot, so is there another way to accomplish it?

Thanks,

Brian

Trying a different route:

group {

  list (item in Items.all())

  {

     item(){label(item.name, onclick={handleTap(item);screen return;})}

  }

}

Doesn't work from within a control: Uncaught ReferenceError: screenCallback is not defined

Going to switch to a screen() rather than a control() to see if the screenCallback error goes away - but this is going to take a little more time.

Hi Brian,

Indeed the second example is the way it should work. I'm not sure why this goes wrong. It might have to do with the construct of screen en controls that you are using. Normally it gets the previous state and goes back to this state.

I confirmed that it works from a screen but not a control.  I will try to isolate it with a smaller program later if its supposed to work.
