Since 1.3.0 a custom serialization is used and this field was introduced for 1.3.0 so I think we can get rid of it completely.

We do not want to insert a if condition in > the {{filter()}} method. So I suggest make IterativeCondition support > {{RichFunction}} interface. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
