Description

Actually the ReplaceText processor can be programmed with a replacement strategy of kind : Regex Replace. This means that the properties Replacement value and replace value can host some EL attribute or parameters. The regex itself will not be in the attribute, but it is intended that the user wants to use the attribute as some part of it. 

eg ov value supported value: (.{${mynumber}})(.*)

but if i prepare the regex search and replacement value in a dedicated attribute of the flowfile then it is not possible to set the property to the attribute content  (see attached image)
