"Request method 'PUT' not supported" with 3.1.0.M2 but works fine with 3.0.6.RELEASE

[sorriso]

Hi,

I started to build a Todos application server sample, it is mainly based on RESTful services with spring-MVC, MyBatis, C3P0 for the server side and the javascript framework Sproutcore 2.0 for the client.

Source code & description can be found @github

All RESTful services tests are successful both with Spring-Framework 3.1.0.M2 and 3.0.6.RELEASE
The application works fine with the 3.0.6.RELEASE, you can add, update, delete data via the client
but I have got an error "Request method 'PUT' not supported" via the client with the 3.1.0.M2
and all other command are working fine (GET, POST, DELETE)
(I just changed the Spring-Framework version number in the POM.xml maven file)

I am not able to know if it is an issue on client or server side...
Did someone have any ideas ?? Thanks in advance

Best regards
