retrieving a list of file name in popup button

[cheonghee at datasonic.com.my (Cheong Hee (Datasonic))]

You probably need to add this in your getFilename() method:

     filename = (String) ((File)fileList.objectAtIndex(index)).getName();

where "fileList" is the attribute of mutable array that you need to set in
getAllFiles;
and "index" is the local attribute int that you need to bind in your pop-up
button "index".

It looked that is no connection between list binding and stringDisplay
getFilename in your pop-up button.

Cheers

Cheong Hee
