how to update domain with hql that has nested property?



I have RaceRegistration class that has a property of type Participant which has attribute bibNumber. I would like to set all bibNumbers belonging to an event to null. The following hql doesn's work. It is giving the error. So it looks like it cannot recognize r.participant.bibNumber.


node to traverse cannot be null!. Stacktrace follows:
java.lang.IllegalArgumentException: node to traverse cannot be null!



How can i update nested attribute of a domain class?


RaceRegistration.executeUpdate("update RaceRegistration r set r.participant.bibNumber = null" +
"where compositeEvent=:comp", [comp: compositeEvent ])

Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes ...
