Default value for nested property: #query.maxResults:int:0#

[Yuri de Wit]

I am having some difficulties trying to set a default for a nested property.
I basically have a a query object that contains a maxResults property and I
pass this query object in a Map to the query. My query contains:
#query.maxResults:int:0#

When query is null, I am seeing a null value being passed and not 0. Am I
missing something or is this as designed?

Thanks in advance,
