Hi
I'm having the same problem. I have a class named Survey which
contains a list of SurveyReplicates (see code below). My app edits
both the Survey and the SurveyReplicates then sends the whole lot to
the server.
@Entity
public class Survey {
.....
@OneToMany(mappedBy="survey", fetch=FetchType.EAGER)
public List<SurveyReplicate> getSurveyReplicates() {
return surveyReplicates;
}
}
Much like the OP, when persist is called on the parent object Survey,
none of the survey replicates are persisted. A little debugging shows
that none of the updates arrive in the SurveyReplicates in the
persist() method on Survey, however the JSON sent to the server
contains the updates to the SurveyReplicates. Updates to the Survey
do arrive.
I wonder if anyone could tell me if persisting object graphs with one-
to-many relationships is supported?
I'm using GWT tip-of-trunk, but saw the same behaviour in 2.1.0.
Thanks
Will Temperley
