springELValueProvider for comparing the string value

Hi All,

Can you please help me for the following situation: Scenario:

I have 3 custom Boolean and string attribute(Suppose One(string),Two(string),isThree(boolean)) in my Product. So, I want the value provider using springELValueProvider for 3rd attribute , which will give the result depending on the first two attribute value(if Two="TWO" like) .

OR How can I write the springELValueProvider, If I want the result of isThree depending on the One value(if One="ONE" like).

This will really help me to move further.
