Re: [rules-users] OptaPlanner: score corruption when using insertLogical with custom objects

Turns out this is a user problem in the equals and hashcode of FamilyStart, not a bug in Drools or OptaPlanner :) @Override public boolean equals(Object other) { if ((this == other)) return true; if (!(other instanceof FamilyStart)) return false; FamilyStart castOther = (FamilyStart) other; return new EqualsBuilder() .append(this.getTimeslot(), castOther.getTimeslot()) // <== must be Family .append(this.getTimeslot(), castOther.getTimeslot()) .isEquals(); } @Override public int hashCode() { return new HashCodeBuilder() .append(getTimeslot()) // <== must be Family .append(getTimeslot()) .toHashCode(); } On 19-07-13 11:56, Geoffrey De Smet wrote:
