    Description

      Some components have to eagerly get property value change, and do some stuff. Sometimes, the target properties support Expression Language (EL).

      However, since current onPropertyModified method only passes String representation of property value, we can't evaluate EL in that method directly.

      It would be useful if we can use subject-less EL functions (i.e without incoming FlowFile) at onPropertyModified, especially with Variable Registry.
