Name and version of the database you are using:

MySQL 3.1.8

I get the above exception when trying to exceute the following code:

teamLeadAccountId = new Long(Long.parseLong(atf.getSelectedManager()));
teamLeadAccount = projectServices.getAccount(teamLeadAccountId);

teamLead = new TeamMember();
teamLead.setAccount(teamLeadAccount);
teamLead.setType(TeamMember.ACCOUNT_TYPE_LEAD);

team = new Team();
team.setLead(teamLead);
team.setName(atf.getName());

teamLead.setTeam(team);

projectServices.create(teamLead);
projectServices.create(team);

A team has a property lead of type TeamMember and TeamMember has a property team of type Team.

Any help would be greatly aprecaited. Thanks.

It looks to me like you have a circular relationship between Team and TeamLead (A team needs a TeamLead and a TeamLead needs a Team) and that these relationship are enforced by constraints (not-null references).

I believe you will not be able to have it work because if you go around Hibernate, your database will not permit it because of integrity constrains.

Please post your mapping for TeamLead. I believe you only posted Team mapping information. Hibernate probably propagates the save event to the Team when saving the TeamLead object and hence the Team.lead property references a transient TeamLead.

Change your object model by allowing a team to be created without a team lead.

Does that help?

Thanks, stupid me it shouldnt have been set that way. Just didnt see it. thanks again.
