whether field value is empty[ScriptRunner]

[arno]

Hi all

I am using ScriptRunner to write a Behaviours and need to determine whether the field value is empty and set the field to read-only. My custom field is text, but I have tried several ways but cannot determine. Could you please tell me the correct code:

---

def Field = getFieldById(getFieldChanged())
def value = Field.getValue()

if ( value != null ){

    Field.setReadOnly(true)

}
