    If not specified, the render method will be invoked for any window state within its general mapping.

    Custom window states can be used as well, as supported by the portal.

- - params
```
String[] params
```
    The parameters of the mapped request, narrowing the primary mapping.
    Same format for any environment: a sequence of "myParam=myValue" style expressions, with a request only mapped if each such parameter is found to have the given value. "myParam" style expressions are also supported, with such parameters having to be present in the request (allowed to have any value). Finally, "!myParam" style expressions indicate that the specified parameter is not supposed to be present in the request.
