halt

optional

Halts execution when used with on-catch, on-empty, or ordered-effects.

Example

...
on-catch {
halt {
dialog {
template ("Invalid Card! Cannot proceed with checkout. Please try again with a different card.")
}
display (order)
}
}
...

The halt key will trigger a result-view that matches the action node. (The view can check the size of the matched node to test whether it was triggered by halt or a successful result.)
