groovy - Do I have to do something special for command objects to get instantiated in grails? -

i have command object in bundle controller. import in controller. create , homecoming instance of command create action:

def create = { def reportcreatecommand = new reportcreatecommand() reportcreatecommand.name = params.name reportcreatecommand.jrxmlfile = params.jrxmlfile homecoming [cmd: reportcreatecommand] }

but save action closure doesn't instantiate object of command properties:

def save = { reportcreatecommand cmd -> if (cmd.validate()){ def reportinstance = cmd.createreport() reportinstance.save() redirect(action:"show", id:reportinstance.id) } else { render(view:"create", model:[cmd:cmd]) } }

apparently cmd null in save closure. command class has 2 properties name , jrxmlfile. know grails should instantiate command object in save method params. have else?

i believe calling cmd.validate() unnecessary, should phone call cmd.haserrors(). command object validating default on creation of object
