EventPropertyGetter
Useful for dynamic properties of the syntax "property?" and the dynamic nested/indexed/mapped versions. Dynamic nested properties follow the syntax "property?.nested" which is equivalent to "property?.nested?". If any of the properties in the path of a dynamic nested property return null, the dynamic nested property does not exists and the method returns false.
For non-dynamic properties, this method always returns true since a getter would not be available unless

eventBean
- is the event to check if the dynamic property exists
