Are there any plans to write an editor plugin for Spring WebFlow? To quote from the WebFlow site, "Spring Web Flow (SWF) is a core module of the Spring Framework focused on the definition and orchestration of page flow within a web application." (see http://opensource2.atlassian.com/confluence/spring/display/WEBFLOW/Home ). I've found WebFlow really excellent for defining complex page flows. It's based on XML configuration files; a graphical editor would make it so much easier to visualise the flows.
Eclipse already has a graphical editor for WebFlow (see http://springide.org/project/wiki/WebFlowEditor ).
