Is it a bug in JUCtrlListBinding.java

Question

Hi,
I came across the following method in JUCtrlListBinding.java.
   protected Object findAndUpdateSelectedIndex(Object val, boolean flag)
      int selIndex = findListIndex(val);
      Object matchVal = null;
      if (selIndex >= 0)
         //this returns a value in the list.
         //this value can match the nullvalue set on the list as well.
         matchVal = mValueList[selIndex];
         if (flag)
            mSelectedIndex = selIndex;
      return matchVal;
   }This method is used to set the selected index, but if the 'selIndex' is less than 0 (which happens if the user has selected the blank or null row from the list), then this method does not update the member variable 'mSelectedIndex'.
The correct implementation should be like this --
   protected Object findAndUpdateSelectedIndex(Object val, boolean flag)
      int selIndex = findListIndex(val);
      Object matchVal = null;
       if (flag)
     mSelectedIndex = selIndex;
      if (selIndex >= 0)
         //this returns a value in the list.
         //this value can match the nullvalue set on the list as well.
         matchVal = mValueList[selIndex];
      return matchVal;
   }Can anybody please check with this?
Thanks

Programmer is a programmer whether writes in java
or cobol language.That's somewhat true, but it has nothing to do with this. Two different programming languages could use the same symbol in different ways. Things are different between languages.
It like that in many areas. 'die' is a verb in English, or 'the' in German. The same thought can require a different symbols in different languages. The thought is the same, but just because the words look similar doesn't mean they are
If you didn't need to know how to do things differently in one language vs. another, wouldn't that mean that if you can program in one, you can program in any language without knowing the differences in the two languages just because you are a 'programmer'
You can still apply the same logic to programs in different languages, but implementing that logic in the specific syntax of a particular programming language is programming.
