This leads to a ClassCastException on line 54 of > AbstractSlingFilterChain: > ... > RequestProgressTracker tracker = ((SlingHttpServletRequest) > request).getRequestProgressTracker(); > ... > I am not sure if this cast is valid in the context of a filter chain. On the > other hand I am not sure wether such a use case (filter that manipulates > request and response) has a chance to run in Sling. > ==> Please note that this servlet filter needs to run as early as possible in > the filter chain > java.lang.ClassCastException: org.webcastellum.RequestWrapper cannot be cast > to > org.apache.sling.api.SlingHttpServletRequest > at > org.apache.sling.engine.impl.filter.AbstractSlingFilterChain.doFilter > (AbstractSlingFilterChain.java:54) > at > org.webcastellum.WebCastellumFilter.internalDoFilter(WebCastellumFilt > er.java:2610) > at > org.webcastellum.WebCastellumFilter.doFilter(WebCastellumFilter.java: > 1710) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
