Hi, 
I have a list object in the table panel and I would like to create a new attribute that contains the length of the list.  Is there a way to do this using a function in the table panel?
Thanks, 
Ruth

Yes, you can use the COUNT(list) function.
But... this function only works on lists of longs, doubles, or strings that can be converted to doubles. And it returns a long so you can only use it in a column of type long. 
(These limitations make no sense because the values in the list shouldn't matter and the length field of a Java array is an int.)
