Pb to cast Expression to ejbql string

[Francois Eyl]

Hi all,

I'm getting a strange behavior using expression and its toEJBQL method.
I'm using this to create my where close from a given Expression. This 
works for me in many cases except for this sample :

When I run the toString() method I get the following string (this is ok) :
 scheduleId in (1, 2, 5, 6, 7, 8, 8, 10)
But when I run the toEJBQL("s") I got the following string (this is wrong) :
 s.scheduleId in ()

So, It seems that when I cast my expression to EJBQL string, parameters 
are lost (numbers from my IN close).

Is it a normal behavior or a kind of bug ?

Thanks
