Grails 1.3.7 - Attempting to create multiple records from a single request

[gcarbone]

All,

I've been searching for hours without success.  Any help would be appreciated.

I have a gsp that allows the person to select a user and multiple roles (user and role are both domains).

I want to create multiple userrole entries (also a domain) with all of the user/role combinations in the request params.

Contrary to most of my searching, regardless if one or multiple roles are selected and are returned as a string.

If there is a single role selection, everything looks OK (eg. "1"), but if there are multiple selected the returned string looks like this: "[1,2]".

I've tried params.list("role"), params.role.values() and a number of other fruitless ways to get it so that I can loop over each of the role entries, such as:

def selectedroles = params.list("role")
selectedroles.each({ r ->
                        println "role id=" + r + " type is "+ r.getClass().name
                })

Any guidance would be appreciated.

Regards,

Gene

Put this as first line inside your action:

params.role = params.role instanceof String ? [params.role] : params.role

params.role.each{
//Your code goes here..............
}

Hope it helps.
