I’m trying to sync cascading fields. I tried hard coding as below, but it did not work.

Also, I have issues with multi select field sync. Kindly request assistance.

Hello Ariel,

I’m trying to set default value to start with. However, i’m getting below error

def DARparent = nodeHelper.getOption(issue, “Test Found In”, “Development”)  
issue.customFields.“Test Found In”.value = nodeHelper.getCascadingSelect(  
DARparent,  
DARparent.childOptions.find

{it.value == “Feature Development”}  
)

def OEMparent = nodeHelper.getOption(issue, “OEM Test Found In”, “Development”)  
issue.customFields.“OEM Test Found In”.value = nodeHelper.getCascadingSelect(  
OEMparent,  
OEMparent.childOptions.find{it.value == “Feature Development”}

)

ERROR:  
NullPointerException: Cannot get property ‘childOptions’ on null object

Please assist.

Hello Ariel,

We have Jira server instance and i’m trying to sync between 2 issue types within same Jira server instance. I was trying to sync between 2 cascading fields.

DAR.issue.customFields.“Test Found In”?.value = OEM.issue.customFields.“OEM Test Found In”.value?.value

Both “Test Found In” and “OEM Test Found In” are cascading fields.

For Multi select field, I was trying to sync between 2 multi select fields

DAR.issue.customFields.“Affected Programs”.value = OEM.issue.customFields.“OEM Affected Programs”.value?.value

Both “Affected Programs” and “OEM Affected Programs” are multi select fields.

Please assist. Thanks.
