LPS-45065 We are using the documentlibrary ConfigurationActionImpl for Media Gallery and Documents and Media display. This is leading to errors because there are validations that only apply to some portlet but not the others. So, as we have different configuration.jsp it makes sense to have different ConfigurationActionImpl per porltet because they are doing different validations.
