Documentation incorrect on the behaviour of how grails.gsp.view.dir is working for custom environments or inconsistent bevaviour of grails.gsp.view.dir for different enviroments

The value of grails.gsp.view.dir is applied differently for different grails environment. I consider this a bug.
If you don't consider it a bug, then you should update the documentation, because it drove me nuts.
Thanks to stackoverflow I managed to resolve the issue:
https://stackoverflow.com/questions/18927812/grails-gsp-view-dir-works-in-dev-but-not-when-deployed-as-war

Start by comparing the documented behavior of grails.gsp.view.dir with the development and deployed-WAR cases described in the issue, using the linked Stack Overflow report as context. Identify the relevant Grails documentation entry, then clarify the environment-specific behavior or document the correct configuration so the two cases are consistent and understandable.
