[jira] [Updated] (NIFI-7525) Create a null() Subjectless Functions to support null type on Expression Language

     [ https://issues.apache.org/jira/browse/NIFI-7525?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Fabrizio Spataro updated NIFI-7525:
-----------------------------------
    Description: 
Reading (and using) nifi expression language, could be useful have a function to set a "null value" easily!
 Today, to resolve this, we can apply some tricks, for example: use an UpdateRecord processor with an unknown RecordPath value or convert record in text (json) and apply ReplaceText processor using a regex + *null* value.
  
 This issue will propose you a new stateless function, called *nullValue()* to retrieve a real "null value"
