expression ? True : False not working on TOS 6.0

[Aamir_Khan]

Hi Guys!
Just brand new in using Talend.  I am using following expression to change values in my in a field Description:
StringHandling.TRIM(row1.Description) == "A"? "Val1" : 
StringHandling.TRIM(row1.Description) == "B" ? "Val2" :
StringHandling.TRIM(row1.Description) == "C" ? "Val3" :
StringHandling.TRIM(row1.Description) == "D" ? "Val4" :
StringHandling.TRIM(row1.Description) 

It's working well in Test of Expression Builder but not working when job runs.
Please, note I am using TOS 6.0.  Please, help me out figuring out where am I wrong.
Thanks All!

may be your expression does not meet to the conditon that is why your not getting expected result on job run. 
or your Input data maybe different than you are comparing. so I would suggest you should use below function to check. 

row1.Description.equalsIgnoreCase("A")? "Val1":row1.Description.equalsIgnoreCase("B")? "Val2" :row1.Description.equalsIgnoreCase("C")? "Val3":row1.Description.equalsIgnoreCase("D")? "Val4" :row1.Description
