Hi folks,

When upgrading to v2.3.0.1, one of our workflow fails at the following 
expression:

operation :if => "${f:operation_level} == 1", :level => 1



with the workitem has the field {"operation_level":1}

The errror that occurs is:

#<NoMethodError: undefined method `first' for 1:Fixnum>trace

At the line of the erro, I see the successive values for the "tree" 
variable before the exception:

[:call, [:lit, 1], :==, [:lit, 1]]

[:lit, 1]

1

Any help?


thanks,
Pedro
