Trying to generate a Session with form type 3 I get the following error messages, when I try to enter the number of view parts:

if I try to enter a 0 (zero):
"Number of key parts should be greater than 1"

If I try to enter a higher value I get:
"Number of key parts should be less than 0" ??????????

That means I cannot generate a session with a form type 3

How many fields are on the index you are trying to use? You need at least two. Then the maximum number of view parts is the number of key fields minus 1.

the index consists out of three parts

found something more:

it looks a so that the probem occurs, if the index has more then two parts.
