I don't think that problem with .equals() or .hashCode() methods, because
I'm using <b>apache EqualsBuilder</b> and <b>apache HashCodeBuilder</b>,
this is 1st, and 2nd my each planning entity has al least unique <b>id</b>.

yes, I'm using accumulate(), but not in this
rule(wxGroupChildClassesInSamePeriodWithDiffLessons) and I've switched to
5.4.Final version, same problem....
