hi, 

I am try to update Single Page properties via V1 API. What I observe is that the property is that instead of one property get updated , it actually wipe out other property.

For example : 

{tradeInformation:{a:1, b:2, c:3}}

when i fire put api with

{tradelnformation:{c:4}}

instead of giving me back 

{tradeInformation:{a:1, b:2, c:4}}

it actually become 

{tradelnformation:{c:4}}

Any idea on how to resolve this?
