[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1049) super's MultipartRequest.getParameterMap() is immutable

super's MultipartRequest.getParameterMap() is immutable ------------------------------------------------------- Key: JBSEAM-1049 URL: http://jira.jboss.com/jira/browse/JBSEAM-1049 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.2.0.GA Environment: Jetty plugin in Maven Reporter: Petr Ferschmann Priority: Minor I am using MultipartFilter directly (in web.xml as first plugin). It tries in MultipartRequest.getParameterMap() to modify Map returned by super.getParameterMap(). It should make copy of it.
