I am calling below method to Update
public void Update(JobCalender jobCalender) {
update(jobCalender); //update() is generic method
}

BfmLogger.logger.info("updating "+t+" instance");
try {
T result = this.entityManager.merge(t);
BfmLogger.logger.info("update successful");
return result;
} catch (RuntimeException re) {
BfmLogger.logger.error("update failed", re);
throw re;
}
}
My Controller Code

jobCalender.setJobPriority((String) model.get("jobPriority"));
String ids="";
#SuppressWarnings("unchecked")
List<Map<String, Object>> listAssets = (ArrayList<Map<String, Object>>) model.get("assetName");// this is what you have already
for (Map<String, Object> map1 :listAssets) {
for (Map.Entry<String, Object> entry : map1.entrySet()) {
if(entry.getKey().equalsIgnoreCase("assetId")){
ids+=entry.getValue()+",";
}
}
}
jobCalender.setJobAssets(ids);
jobCalenderService.Update(jobCalender);
}
while Updating JOB_CALENDER Table it is Adding NULL Value For MAINTAINANCE_TYPE_ID Column
Please Help Me
Thank You
