Displaying a field based on another field selection


I am hoping to implement the following, if possible.

Custom Fields to be created:

A - Test
a.1. E
a.2. R
a,3. T

B - Test 1
b.1. J
b.2. K
b.3. L

C- Test 2
c.1. I
c.2. O
c.3. P

Only A & B are compulsory when creating a ticket
But when a.1 and b.3. is selected then A, B and C are compulsory


Not too sure how this would be implemented but I suspect a specific code for this, but that is a bit beyond my capability.

Hi there

Taking you at your word that you want field C to be required when a.1 is selected and at the same time b.3 is selected, you could try a script like this:

def fieldA = getFieldByName('A - Test') //this is the label for the field A
def fieldB = getFieldByName('B - Test 1')
def fieldC = getFieldByName('C - Test 2')

def fieldAValuesThatTriggerFieldCRequired = ['a.1. E'] //this has to be the label of the option
def fieldBValuesThatTriggerFieldCRequired = [ 'b.3. L'] //you could add additionoal values here in coma separated list
def valueA = fieldA.value
def valueB = fieldB.value

def fieldCIsRequired = valueA in fieldAValuesThatTriggerFieldCRequired && valueB in fieldBValuesThatTriggerFieldCRequired

You would put this code in the behaviours section of script runner. Create a new configuration that maps to your project. Then edit the behaviour configuration and add field A and Field b.

For each of those 2 fields, add a server-side script and put the script above in each of those server-side scripts. These server-side scripts run each time values change in each of those fields so that the fieldC can be re-evaluated each time.

To make fieds A and B required, you can do it with the behaviour toggles on each field. Or you can make this globally required in your project's field configurations.
