Hello,

I'm currently using AliasToBeanResultTransformer to map my query to a bean. My criteria query uses the sum aggregation function.

My problem is that the aggregation can be empty and so the sum function return null.

When AliasToBeanResultTransformer try to map the result to my bean, Hibernate throw the PropertyAccessException exception


Any idea to solve my issue?

Thanks in advance,

Nicolas

Can't your bean have an object wrapper for quantiteReserve instead of a primitive? Especially if you are using Java5, where the autoboxing/unboxing would automatically handle the primitive->object conversion.

I've tried to put the two function :
void setQuantiteReserve(Double quantity);
void setQuantiteReserve(double quantity);

Not matter it don't run. It throw always the same exception.

Currently my only solution was to create a class which implement ResultTransformer

Sorry I was not more clear, the PropertyAccessor in the AliasToBeanResultTransformer uses field level access, and looks to be bypassing the setters. What I originally meant was: is it a problem to define your field as a primitive wrapper instead of a primitive.

I've try too and it casts me :

;)

Ok, the problem is solved.

I've remplaced Double by Float

Now I just must find why ;)

Thanks for your help Ananasi
