Hi,
Hoping for some help, have tried this on my Apex 18 version and the online version (apex 20) and get the same results, i must be missing something.
I have an interactive grid and what i want to do is set a value of a column based on a PLSQL Exspresion triggerd on the change of a selection list of another column.
However with the dynamic action configuration i have (screen grabed below) , clicking on any cell of the row, triggers the PLSQL and sets the value.
Any advice would be very greatfully recieved.
* i have hardcoded a PLSQL expression to 50 just to prove the point.
