[Vuejs]-Cannot update entity

Well, I’ve looking in some articles and changed the way I update the entity:

@PutMapping("/update")
public StructureElement update(@RequestBody StructureElement se){
    StructureElement databaseElement;
    logger.info("Call to StructureElementController.update with se = " + se);
    this.connectToDatabase();
    try{
        databaseElement = this.repository.findOne(se.getId());

        if(databaseElement == null){
            logger.error("Could not find StructureElement to update. se = " + se);
            return null;
        }

        // Update
        databaseElement.setDescription(se.getDescription());
        databaseElement.setTag(se.getTag());
        databaseElement.setOptional(se.isOptional());
        databaseElement.setRepetitive(se.isRepetitive());
        databaseElement.getSignature().setModificationDate(new Date());

        databaseElement = this.repository.save(databaseElement);
        logger.info("Updated SE = " + databaseElement);
    }catch (Exception e){
        logger.error("Could not update structure element. se = " + se, e);
        return null;
    }
    return databaseElement;
}

Now this works.

Seems that Spring data JPA doesnt want to update an entity like a simple JPA EntityManager….
