Subject: Possible solution to array bugs

This may be of interest to people who, just like I, encountered crashes when using (dynamic) arrays.

I got GPFs on the following occasions:

• trying to set a local variable to a array that was defined as a user property
• returning an array from a to get handler

Luckily I finally had some reproducable cases and I have found a very simple solution that works for me. I strongly believe the GPFs are caused by elements in the array that have a null value.

I use this general script before setting an array as a user property or returning it from a handler:

-- this is the script for a 2-dimensional array 'l_some_array'        
-- change for other dimensions
step i from 1 to item 1 of dimensions (l_some_array)
   step j from 1 to item 2 of dimensions (l_some_array)
       if l_some_array [i][j] = null
          clear l_some_array[i][j]
       end if
   end step
end step

Any comments are welcome,
Andre
