Christoph Lenggenhager updated WW-4257:
---------------------------------------

    Description: 
With version 2.3.16, the {{ParametersInterceptor}} uses the same method to 
validate parameter names and property names.
As we use the {{ParameterNameAware}} interface to implement parameter 
whitelisting on action level, this breaks our case.

It might not be how it is intended, but validating a property independent of 
the actual bean breaks our current implementation.

Possible fixes would be:
- alter {{ParameterNameAware}} to have an additional separate method to 
validate properties
- introduce a new {{PropertyNameAware}} interface
- introduce a new {{ParameterAndPropertyNameAware}} interface

One could also consider to ignore the {{ParameterNameAware}} interface when 
validating properties, as for a parameter {{foo.bar}}, the values {{foo.bar}}, 
{{foo}}, and {{bar}} are passed to the ParameterNameAware interface, which one 
could see as a bit redundant. Especially given the fact that a context in the 
case of property validation is not provided. Therefore, it is impossible for 
the implementation to distinguish between a parameter and a property.
