[rules-users] error inserting object into working memoery

[Darko IVANCAN]

Hi,

When inserting an object into the WM it is getting passed into the
Rete-Tree.
Said this, is becomes clear, that some tests get applied and thus a test
like

    when
       p: Person(name="Eric");
    then
       ....

will throw a NPE when name is null.

hope this helps,
Darko
