[rules-users] Problems with BRMS

Im having problems using the BRMS 4.0GA and BRMS 4.0 stand alone (v 1.0). Things just crash without reason... importing models crash sometimes, and trying to create LHS in business rules got stall... not showing any option to add fact or whatever... In standalone version I have this error trying to load a model jar: ERROR 13-08 18:14:32,552 (ApplicationContext.java:log:675) Exception while dispatching incoming RPC call com.google.gwt.user.client.rpc.SerializationException: java.lang.ClassNotFoundException: org.drools.brms.client.rpc.RuleAsset at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamReader.dese rialize(ServerSerializationStreamReader.java:156) at com.google.gwt.user.client.rpc.impl.AbstractSerializationStreamReader.re adObject(AbstractSerializationStreamReader.java:61) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamReader.dese rializeValue(ServerSerializationStreamReader.java:70) at org.jboss.seam.remoting.gwt.GWTRemoteServiceServlet.processCall (GWTRemoteServiceServlet.java:285) at org.jboss.seam.remoting.gwt.GWTRemoteServiceServlet.doPost (GWTRemoteServiceServlet.java:181) at javax.servlet.http.HttpServlet.service(HttpServlet.java:709) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter (ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter (ApplicationFilterChain.java:173) at org.jboss.seam.web.ContextFilter.doFilter (ContextFilter.java:56) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter (ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter (ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke (StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke (StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke (StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke (ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke (StandardEngineValve.java:107) at org.apache.catalina.valves.AccessLogValve.invoke (AccessLogValve.java:541) at org.apache.catalina.connector.CoyoteAdapter.service (CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process (Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol $Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket (PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt (LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool $ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:613) Caused by: java.lang.ClassNotFoundException: org.drools.brms.client.rpc.RuleAsset at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java: 319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:242) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamReader.dese rialize(ServerSerializationStreamReader.java:135) ... 24 more PD: I checked the classes/enums in my model jar and all of them are Serializable...
