[coldbox-3.5.2] duplicated values with remote requests

I just updated an application from 3.5.0 to 3.5.2 and got a strange behaviour with ajax remote requests.

After calling the remoteproxy with jquery async call all paramters in the requestcolletion have double values.

p.e. I call remote.cfc and the doProcess method for an event “cart.addItem” with a couple of parameters

like “productname=‘myproduct’”. It gets submitted correctyl but when I dump the rc in handler ‘cart’ and action ‘additem’ the value is duplicated to “myproduct,myproduct”.

that happens with all parmeter values…it was fine till 3.5.0

any Ideas?
