Merge Grails request body and params into single command?

Question

Currently in my action method I unmarshal the request body and request params into two separate commands.

def someAction(BodyCommand bodyCmd) {
    ParamsCommand paramsCmd = new ParamsCommand(params)

    // Do something with bodyCmd and paramsCmd after
    // validating both
    if (bodyCmd.validate() && paramsCmd.validate()) {
        ...
    }
}

I'd like to combine the commands and instead have just a single command.

def someAction(ActionCommand cmd) {
    cmd.merge(params)

    // Do something with cmd after validation
    if (cmd.validate()) {
        ...
    }
}

Is it possible to merge the params into the request body command that's automatically unmarshalled by Grails?

unsure if bindData will help http://docs.grails.org/latest/ref/Controllers/bindData.html — V H, May 25 '16 at 17:50
if you have controller action with command(s) as a parameter, it will be binded automatically, what more do you want to do? — practical programmer, May 26 '16 at 09:51

Looks like Grails 2.5.0 does support a simple way to merge params into a domain class or command object.

cmd.properties = params
