There is a dropDown for which there is a valueCahngeListener. On exceuting code

valueChangeEvent.getOldValue().. its always giving null, But valueChangeEvent.getNewValue() is giving the current value that is selected in drop down.
Any cue why it is coming so.

The getOldValue() gives the originating value as it was during initial display/render of the page.
The getNewValue() gives the newly selected value as the client has chosen.

What did you expect then?
It is sorta covered in the JavaRanch Style Guide.
