How to add Groovy condition for a checkbox field in post function

[anil musunuru]

I have a Custom Field ID=11111 ,Custom field Name=Test , Checkbox Values =Apple,Oranges,Lemon.

I am writing a groovy condition expression where if it has one of the above values it should return TRUE, but instead it always returns FALSE, here is what i am using as condition expression 

issue.get("customfield_11111") == "Apple"

This worked for me,

issue.get("Customfield Name")?.find() { it.getValue() == "Customfield Value" } != null)

Hi Anil,

Per Jamie's answer here, you should do the following: 

sourceValue = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject("customfield_11111"))

if (['sourceValue']*.value.contains("Apple")) { ... }
