I am running gwt 2.3 and smargwt power nightly 2.5. I am having trouble debugging why an rpc dmi call won't reach the server. The dmi call looks like the following

Code:

 DMI.call("myapp", "ManagerDmi", "createAndStoreFoo", callback, new Object[]{myRequest});

The myRequest object is a class that I have in the shared folder and the class implements java.io.Serializable. The server side method signature is

Code:

 public String createAndStoreFoo(ServletContext servletContext,
                                      HttpServletRequest request,
                                      MyRequest myRequest)

The error that I get when the code tries to call the dmi is

Code:

 14:42:46.058 [ERROR] [myapp] Uncaught exception escaped

There is another error thrown when the web app is loading that I don't know if it has anything to do with the error.

Code:

DMI does not support sending just anything that is serializable. It supports Java Collections, Arrays and primitives as well as Record. See the server-side API DataSource.setProperties() for how this data can be applied to populate beans if you want them.
