[rucksack-devel] Error unbound Slot Transaction-id

[Helmut G. Enders]

Here is a complete test case with sbcl.

; SLIME 2008-10-30
CL-USER> (require :rucksack)
("SERIALIZE")
CL-USER> (rucksack:with-rucksack (rs "/tmp/db")
	   (rucksack:with-transaction ()
	      (defclass user ()
		((no :initarg :no :accessor :no :index :number-index :unique t))
		(:index t)
		(:metaclass rucksack:persistent-class))))
#<RUCKSACK:PERSISTENT-CLASS USER>
T
CL-USER> (rucksack:with-rucksack (rs "/tmp/db")
	   (rucksack:with-transaction ()
	     (make-instance 'user :no 1)))

-->> ERROR:  Unable to display error condition
              [Condition of type UNBOUND-SLOT]


CL-USER> ;; Now the same call, but with a NIL after the make-instance:
          ;; No Error.
          (rucksack:with-rucksack (rs "/tmp/db")
	   (rucksack:with-transaction ()
	     (make-instance 'user :no 2) nil))
NIL

There is no meaningful backtrace.
