How to set 'none - none' for cascading field using Behaviour?


I have been trying to set some default value for cascading field based on another cascading field, I think I can able to set the value but could not able set the none - none value when others value has been set.

This article helps me to get cascading field value and This library helps me to set value for cascading field.


User selects

Cascading 1 -> A1 - AA1

Behavior sets

Cascading 2 -> X1 - XX1

When users change the value of Cascading 1 other than A1 - AA1, the cascading 2 still shows X1 - XX1, I wanted to set it to none - none for Cascading 2.

My script looks like

def selectListField = getFieldById(fieldChanged)
def selectListValue = selectListField.value

if (selectListValue.size() > 1 && (selectListValue[1] == "Framework & Tools" || selectListValue[1] == "Operational Efficiency" || selectListValue[1] == "Strategic Tech")) {
field.setFormValue([parentOption.optionId, childOption.optionId])

if (selectListValue.size() > 1 && selectListValue[1] == "Internal Integration") {
field.setFormValue([parentOption1.optionId, childOption1.optionId])

if (selectListValue.size() > 1 && selectListValue[1] == "Reduce Cost of Implementations") {
field.setFormValue([parentOption1.optionId, childOption2.optionId])
field.setFormValue([null, null])

Hi @Teja,

 I tested below codes and both works fine for me to reset values for cascade field

cf.setFormValue([null, null])

cf.setFormValue([-1, -1])




Hi @Leo 

It works when I select both values from Cascading 1.

I need it to be set 'none - none' for Cascading 2, when Cascading 1 selects only the parent value?

@Teja, I've tested below code. it clears the value of cascade 2 when cascade 1 parent value changes

def ct = getFieldByName("Cascade One")
def ctval = ct.value as List
if(ctval.size() < 2 && ctval[0] != "alpha"){
getFieldByName("Cascade Two").setFormValue([null, null])
Like Teja likes this

Thanks @Leo 

Sure, I will verify this.
