RE: problem submiting List-Backed Indexed ActionForm

2005-01-16 Thread Karr, David 
If you don't understand how the code works, there's no better solution
than running the application in your debugger and stepping through the
Struts and Commons source code.  When you get to the line that throws
the NPE, you'll have the first clue about what's going wrong.  You'll
need to make sure you have the source distributions corresponding to the
binary versions that you're using.  It's easy enough to know that you'll
need the source distribution for Struts 1.2.4, but it might not be
obvious that you'll need the source for Commons BeanUtils, version
1.6.1.  This is from the install guide.

Barring that, it would have helped if you'd included the actual
exception stack trace.  Someone could then look at the actual line to
get a clue about what's happening (although running in the debugger is
still better).

That being said, the most likely answer is that your fields list is
null, or too short.

Looks like you are not properly initializing your fields (ArrayList)
 in FormActionForm. You should initialize it while declaring or in the
reset()
