I searched around on the forums but was unable to find a solution to this problem.
I am trying to update a foreign key in one of my tables.
Basically a form has a select with a list of "BugSeverity" entries with the ID as the value
The Bug table has a foreign key constraint to the BugSeverity table
I am not trying to modify the BugSeverity table just the Bug table.
Here is all the code that is used for this.
The error:
Code:

The DAO code:
Code:
@Transactional(propagation=Propagation.REQUIRED)
public void saveBug(Bug bug) {
sessionFactory.getCurrentSession().saveOrUpdate(bug);
}
The business logic code:
Code:
public void saveBug(Bug bug){
long time = Calendar.getInstance().getTimeInMillis();
bug.setBugseverity(softwareDAO.getBugSeverity(bug.getBugseverity().getSeverityId()));
Bughistory history = new Bughistory();
history.setDateOccurred(time);
history.setHistoryItem("Bug Updated");
history.setBug(bug);
Set histories = new HashSet();
histories.add(history);
bug.setBughistories(histories);
softwareDAO.saveBug(bug);
}
The form submission code:
Code:
package com.odinnet.mvc;
import javax.servlet.http.HttpServletRequest;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.odinnet.service.SoftwareService;
import com.odinnet.data.Bug;
import java.util.HashMap;
import java.util.Map;
public class EditBugController extends SimpleFormController{
public EditBugController() {
setCommandClass(Bug.class);
setCommandName("bug");
}
@Override
protected Object formBackingObject(HttpServletRequest request) throws Exception{
Bug bugForm = (Bug)super.formBackingObject(request);
bugForm = softwareService.getBug(Integer.parseInt(request.getParameter("id")));
return bugForm;
}
@Override
protected Map referenceData(HttpServletRequest request) throws Exception {
Map data = new HashMap();
data.put("software",softwareService.listSoftware());
data.put("severities",softwareService.listBugSeverities());
data.put("priorities",softwareService.listBugPriorities());
data.put("statuses",softwareService.listBugStatuses());
return data;
}
@Override
protected ModelAndView onSubmit(Object command, BindException bindException) throws Exception {
Bug bug = (Bug)command;
softwareService.saveBug(bug);
return new ModelAndView(getSuccessView());
}
private SoftwareService softwareService;
public void setSoftwareService(SoftwareService softwareService){
this.softwareService = softwareService;
}
}
I am unsure of what I am doing wrong, but this (to me) is all experimental code so i can change anything include the database as I please.
Any help would be appreciated.
