Cannot create two or more top down web services in a web project

-create a new ear project ("Ear")
-create a new dynamic web project ("WsWar")
-create a top down ws from some wsdl using wtp wizard in WsWar project

• ws project WsWar, ear project Ear, server runtime JBossAS6.0, ws runtime JBossWS
  -create another top down ws from different wsdl there
• ws project WsWar, ear project Ear, server runtime JBossAS6.0, ws runtime JBossWS

=> wizard ends with "The Web Service Name has been used in the web.xml of the web project." error message and doesn't allow user to finish it but all I'm trying to do is to create two completely different services in one project

message is comming from line 190 in org.jboss.tools.ws.creation.core.commands.MergeWebXMLCommand
