Mapping to a property named 'value'

I have no clue, but I could see value being a reserved property name.

I'm getting the following exception for seemingly mysterious causes:

----------------------------

TestCase 'Domain.IbatisTest.TestGetCars'

failed: System.NullReferenceException : Object reference not set to an instance of an object.

 &nbsp; &nbsp; &nbsp; &nbsp;   ; C:workDomainIbatisTest.cs(40,0): at Domain.IbatisTest.TestGetCars()

----------------------------

The .Net class which I'm mapping to has a property named 'value' which seems to be causing this.

If I remove the mapping to the 'value' property everything runs fine, or if I rename the property to e.g. 'value2' and update the mapping it works fine.

 

Bug? Or is using 'value' as a property name a big no-no?
