default value of DropDownByIndex

hello,

i am searching for the possibility to access the default value of a dropdown element in java WebDynpro. I exactly mean the "blank" value in the top of a drop down box.

In my scenario i want to display different data in a table related to the selected values in the drop down box. If the user choose the "blank" data should be diplayed as well.

does anyone have a idea??

thanks in advance,

regards,

rene
