Scriptrunner Script Field - using variables with math functions

[Larry Lowe]

I am creating a custom script field using Scriptrunner.

For some reason, when i try to use a variable in a math function (i.e. var1 + var2) it only returns null. If i put in standard numbers (i.e. 9 + 20) then it returns the value.

Here is the code so far, but i plan to add more custom fields once i get this working:

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.customFieldManager
def cfAlignmentScore = customFieldManager.getCustomFieldObjectByName("Infra Alignment Score")

def alignment = issue.getCustomFieldValue(cfAlignmentScore) as int

if (alignment != null) {
return (alignment * 5)
}
else {
return null
}

As a coder, you do not actually know what is in the custom field.  Trying to cast it to an int automatically might work if the type of data is compatible, but my guess is that it is not.

Try dropping the "as int" on the "def alignment" line first, and then check what the logs say as well (they will usually catch script errors with something more useful than my guesses)

After removing the "as int", i get the attached error. The custom field type is a single select list.

Ok, that suggests that the field does not contain a number at all.  You'll need to work out some code to convert it to one before you can multiply it with another number
