could not initialize proxy - no Session, accessing the session object in the filters class

Question

i'm a bit new on the groovy grails technology and i'm having a problem with this one

i looked at this could not initialize proxy - no Session but the application don't get stale too long

I am trying to access the session object on my SecurityFilter placed on the config subfolder. I just wanted to do a check for every request on the controllers to verify if a user has the rights to do such actions.

class SecurityFilters {
    def filters = {

    userFilterList(controller:"user", action:"list") {
        before = {
            if (!session.user.accountType.equals("Admin")) {
                redirect(uri: "/")
            }
        }
    }
    userFilterShow(controller:"user", action:"show") {
        before = {
            if (!session.user.accountType.equals("Admin")) {
                redirect(uri: "/")
            }
        }
    }
    userFilterEdit(controller:"user", action:"edit") {
        before = {
            if (!session.user.accountType.equals("Admin")) {
                redirect(uri: "/")
            }
        }
    }

    }
}

but I get this error

before I get to this point I placed the user object on the session object right after doing the login instructions but I am not sure what happened that the session object became not available

some of the properties of the user object were not retrieved, so in the login when I put the user object in the on the session, I also had to manually transfer the property that I needed so I could retrieve again for later use

session.user = user //not enough
session.user.accountType = user.accountType

now I was able to retrieve the user object from the session object and get the property that I wanted to get

could not initialize proxy - no Session, accessing the session object in the filters class
