at moment, we can use @table_ref_id.otherColumn@ in logic expression.
but have a limit, table_ref_id must is column of table of current tab.
need improve to can evaluate when table_ref_id lie in other parent tab.
as a workaround maybe you could have a virtual column on the tab using the logic expression?
which is the use case of this one? which logic do you refer (display, mandatory, readonly)?
1. at long time ago, i use this workaround (make virtual column)
i just accidental see code and think about improve it.
it's worth to improve?
2. i remember my case is display logic. but seem it's also apply for other logic (mandatory, readonly)
now, i use this syntax to read-only logic of tab but it don't work.
dig into code, i see this feature implement by IDEMPIERE-701, and just for field.
it's worth to bring this feature to other logic evaluate logic.
