Is it possible to reference a current row (and it’s attributes) from within ValueRule XPath expression (Ruleset)?
Simpliest illustrationve use case:
Imagine a datastructure with one entity (ENTITY1) and column COL1 and COL2. I would like to fill COL2 from the value of COL1, so I would expect XPath (of Value Rule with target field COL2) would look like something:
@COL1
or
current()/@COL1
or
/row/@COL1
or
/ROOT/ENTITY1[@Id=current()/@Id]/@COL1
(that’s what I was trying, trying to guess if there is some context of current row)
This use case can be of course solved by using computed function entity field, but I need this for more complicating computations involving selecting (by XPath) from parallel entities.
