How can I create a Behaviour condition based on the value of a text field

[Mick Lovell]

Hello,

I have a select list field that I want to hide unless another text field has a value.

I'm trying to implement the solution posted at https://community.atlassian.com/t5/Jira-Core-questions/Condition-on-a-custom-field-basis-for-triggering-behaviour/qaq-p/850186

My code for the behaviour is:

def amountToBePaidToOther = getFieldByName("Amount to be paid to Other")
def ftr = getFieldById("FTR/NPR Justification")
log.debug("Amount to be paid to Other value" + amountToBePaidToOther.getValue())

if (amountToBePaidToOther.getValue() == null) {
ftr.setHidden(true);

} else {
ftr.setHidden(false);

}

I've tried configuring the script to both fields.

When I view the customer portal, the select list field is still visible with no value in the text field.

Thank you.

Instead of null, I used "" and the Behaviour works.

def amountToBePaidToOther = getFieldByName("Amount to be paid to Other")
def ftr = getFieldById("FTR/NPR Justification")
log.debug("Amount to be paid to Other value" + amountToBePaidToOther.getValue())

if (amountToBePaidToOther.getValue() == "") {
ftr.setHidden(true);

} else {
ftr.setHidden(false);

}

hi. Change this line:     def ftr = getFieldById("FTR/NPR Justification")

on 

def ftr = getFieldByName("FTR/NPR Justification")

Thank you Roman.  The FTR field still does not react to the behaviour, but thank you for catching that error.
