Kotlin: "when Statement" Skips Condition

I am trying to validate a form in android using Kotlin. My problem is, that my when statement does not work like it's supposed to work. It doesn't check for the other conditions wh

Solution 1:

when works exactly the way it's supposed to work (emphasis mine):

when matches its argument against all branches sequentially until some branch condition is satisfied.

So it executes at most one branch, the first matching one, and then it stops.

If you want to continue to match other branches, just use a series of unrelated if statements instead:

// It is possible, that both btNumber and ddSalutation are false, but it only checks for btNumber// and then jumps outfunisFormValid(): Boolean {
    var error = 0if (btNumber.value.isNullOrEmpty()) {
        btNumberEM.value = emptyFieldError
        error = 1
    }
    if (btNumber.value.toString().length < 7) {
        btNumberEM.value = btNumberTooFewChar
        error = 1
    }
    if (ddSalutation.value == ddSalutationTextPlaceHolder) {
        ddSalutationEM.value = ddSalutationNotSelected
        error = 1
    }
    if (etFirstName.value.isNullOrEmpty()) {
        etFirstNameEM.value = emptyFieldError
        error = 1
    }
    return error == 0
}
