Multiple validations

Hi Alex - If there are multiple validations on a field, is there a way to validate in an order and display error messages accordingly instead of displaying all at once?

Thanks

Hi Manish,

You can't define an order through the UI, but you can do so through your
XPath expressions. Say you have 3 XPath expressions: `a`, `b`, and `c`, then
you can rewrite them as `a` (unchanged), `b and not(a)`, `c and not(a) and
not (b)`. This way, at most one error will show, and if there are multiple
problems, they will show in the order you specified. You'll let me know if
this works for you!

‑Alex

Hi Manish,

Let me elaborate on my earlier example. Say you have three conditions you
want to be true, and for each one a message:

- 1. XPath: x1, message: m1
- 2. XPath: x2, message: m2
- 3. XPath: x3, message: m3

Then, in Form Builder, you enter the following constraints:

1. x1 ⇒ m1
2. x2 and not(x1) ⇒ m2
3. x3 and not(x2) and not (x1) ⇒ m3

This way only one message is shown at any given time, and you can control
the order in which the messages are shown if there are multiple errors.
You'll let me know if this works for you!

Hi Manish, do the XPath expressions I mentioned make sense? Would this work
in your case?
