Object passed to Decision Table not set in Action columns

Hi,

When I pass an object as parameter to my decison table. this object is set (populated with already assigned values) in conditions but not in action columns. When I call some getters in Action columns already set before , I got a null value in all fields ! It works fine in version 7.4.1.Final : I got all values , but when I switch to the version 7.6.0.Final , it doesn't work !

I thank you,
Adil
