grails domain class .list() method with params

Question

I have two domains that are connected with one-to-many relation - One User may have many Associations. I want to view all associations that belong to this user. I'm using scaffolding plugin. So code that should return list of Associations in AssociationController looks lile this:

def index(Integer max) {
    respond Association.list(params), model:[associationInstanceCount: Association.count()]
}

And on the User view page I have the following code:

<g:form controller="Association" >
    <fieldset class="buttons">
        <g:hiddenField name="user.id" id="user.id" value="${userInstance.id}"/>
        <g:actionSubmit class="list" action="index" value="${message(code: 'default.list.label', default: 'Show Associations')}"/>
    </fieldset>
</g:form>

When I press this actionSubmit user.id is sent with the request and it is within params map (I checked it with debug) but for some reason Association.list(params) returns all Associations (for all users) despite the fact that I'm using this user.id within params. A also tried rename user.id to just user and it didn't work either. Seems like this .list() should be used only for sorting or I'm doing something wrong. Can you help me with this please? Thank you!

To clarify the given answer: list( params ) returns ALL results for the domain object, and accepts only sorting (order by) and view-port (limit/offset) parameters. It does not provide any where clause (well, apart from discriminator-column)

UPDATE:

you can use findAllBy*:

Association.findAllByUserId( params.long( 'user.id' ), params )

or criteria if you need to make your query more complex:

Association.withCriteria{
   eq 'id', params.long( 'user.id' )
   maxResults params.int( 'max' ) ?: 10
   firstResult params.int( 'offset' ) ?: 0
   if( params.sort && params.order ) order params.sort, params.order
}
