Seems to work fine with me, without any declared interface. Make sure your actual trunk port is "up". This is a config snippet from one of my SRX240s:

ge-0/0/0 {
        unit 0 {
            family ethernet-switching {
                port-mode trunk;
                vlan {
                    members [ vlan-10 vlan-99 ];
                }
            }
        }


    vlan {
        unit 10 {
            family inet {
                address 10.20.0.1/30;
            }
        }
        unit 99 {
            family inet {
                address 10.20.0.5/30;
            }       
        }           
}


vlans {
    vlan-10 {
        vlan-id 10;
        l3-interface vlan.10;
    }
    vlan-99 {       
        vlan-id 99; 
        l3-interface vlan.99;
    }               
}                   


chrisk at CLGR01-FW03> show vlans 
Name           Tag     Interfaces
default        1      
                       None
vlan-10        10     
                       ge-0/0/0.0*
vlan-99        99     
                       ge-0/0/0.0*
