Hi, (cross posted from users list as this is most likely more relevant to this list, being a possible bug)
I believe I've uncovered an error in version 2.1.1 of SimpleRequestProcessor when there are no invocations and only operations in a RequestMessage from the client (stacktrace at end of email). I'm checking here before creating an issue. I am using an editor on the client to modify a property, then flushing and firing. So the RequestMessage from the client is: --- {Operations=[{PropertyMap={title=150349-0 Title CHANGED}, ServerId=IjY1Zjg4ZjVlLWFlNDItNDcxYi04NGNkLWE2MWJmOGUxNzBjZCI=, Operation=UPDATE, Version=MQ==, TypeToken=au.projectx.gwt.request.ArticleProxy}]} --- With the following stacktrace: --- [#|2010-12-21T15:05:48.626+1100|SEVERE|glassfish3.0.1|com.google.gwt.requestfactory.server.RequestFactoryServlet|_ThreadID=28;_ThreadName=Thread-1;|Unexpected error java.lang.NullPointerException at com.google.gwt.requestfactory.server.SimpleRequestProcessor.processInvocationMessages(SimpleRequestProcessor.java:414) at com.google.gwt.requestfactory.server.SimpleRequestProcessor.process(SimpleRequestProcessor.java:218) at com.google.gwt.requestfactory.server.SimpleRequestProcessor.process(SimpleRequestProcessor.java:125) at com.google.gwt.requestfactory.server.RequestFactoryServlet.doPost(RequestFactoryServlet.java:118) at javax.servlet.http.HttpServlet.service(HttpServlet.java:754) --- It seems to me that either SimpleRequestProcessor.processInvocationMessages() needs to cater for a null List<InvocationMessage> or RequestMessage.getInvocations() should return an empty list instead of a null. -- Cory -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
