Looks like a bug. PageLoaderProcessor.java:249 is:
// This may return null if the parameter is not bound in the
loading component.
Binding existing =
loadingComponentBindingMap.get(loadingParameterName);
It looks like loadingComponentBindingMap may be null when the loading
component is a page.
The error is responsable ... where are you inheritting the readOnly
parameter from? ... but the a NPE is not acceptible, it should be an
exception that identifies what you are doing wrong (using inherit:
where it doesn't make sense).
