Interceptor::findDirty function

Hi
I'm trying to use findDirty function of Interceptor interface to exclude some properties names from update query(i don't want them to be updated when function saveOrUpdate was called on entity). In order to accomplish that i'm returning from findDirty function array of indeces of all properties but this particular property name :

Code:

public int[] findDirty(Object entity, Serializable id, Object[] currentState, Object[] previousState, String[] propertyNames, Type[] types) {
int [] ret_val=new int[propertyNames.length-1];
int j=0;
for (int i = 0; i < propertyNames.length; ++i) {
  if(!propertyNames[i].equalsIgnoreCase("image")){
   ret_val[j]=i;
   ++j;
  }
}
return ret_val;
}

The problem is that image column is still updated...
What am i doing wrong? Do i use findDirty method correctly?
Thanks

If the index of the property "image" is 0, it will still get updated since your ret_val will contain one unused slot preinitialized to 0 (the local variable j is useless for what you're trying to do). You'd need a variable sized ArrayList for this which you convert to int[] at the end. Also, if you don't want to muck around with the indices you can instead try setting currentState[i] = previousState[i] if propertyNames[i].equals("image").
