Controller can't handle Entity creation with multiple parameters

Hi,

I am currently developing an application which lets users create clients
and associate one or more emails to them.

Here’s the Spring Roo script which I wrote to generate the application:

---------------------------------------------------------------------------------------
# Email Table
entity jpa --class ~.model.Email --testAutomatically
field string --fieldName email --notNull --sizeMin 1 --sizeMax 30

# Note Table
entity jpa --class ~.model.Note --testAutomatically
field string --fieldName note

# Client Table
entity jpa --class ~.model.Client --testAutomatically
field string --fieldName name --notNull --sizeMin 1 --sizeMax 30
field set --fieldName emails --type ~.model.Email --cardinality ONE_TO_MANY --mappedBy client
field set --fieldName notes --type ~.model.Note --cardinality ONE_TO_MANY --mappedBy client

# Email Table
focus --class ~.model.Email
field reference --fieldName client --type ~.model.Client --cardinality MANY_TO_ONE

# Note Table
focus --class ~.model.Note
field reference --fieldName client --type ~.model.Client --cardinality MANY_TO_ONE

# MVC
# change project type to web application and output war artifact
web mvc setup
# Generate Controller, etc.
web mvc all --package ~.web
----------------------------------------------------------------


Whenever I create new e-mails in my running application, I get a
Status 400 error stating that
“the request sent by the client was syntactically incorrect”.

The data sent over the network by my browser to the application are the following:

POST /myapplication/emails

and

Email=email1&&client=client1

in the POST’s BODY.

So it would seems as though the application can't handle /emails queries
with parameter values.

I have added breakpoints all over the EmailController.....aj (Aspect J) class and run my application
in debugging mode to see where it lands in the code when I click the Save Button on the
Email Creation Page.

What I have discovered is that it lands nowhere, not even in the

@RequestMapping(method=RequestMethod.POST, produces="text/html")
public String EmailController.create(@Valid Email email, BindingResult...

method as one would expect.

How should I handle POST queries sent by the email-create form,
with two parameters (client and email), in the EmailController or elsewhere?

Many thanks.
