Re: retrieving a list of file name in popup button

Hi, Yamuna,

I don't see any obvious problems with the code you shared, but  
information is missing.

It would help to know:

   * which line in the code you showed us was line 122 (that is,  
which line threw the exception).

   * how you've defined downloadDir and enFile

   * whether, and to what, you've bound your popup button's item binding

Clearly, some variable that you're expecting to have a value is  
instead set to null, but it would be hard to figure that out with  
what you've shown us.
