Refreshing Parent fields after Back Navigation

grendizer Jan 12, 2011 11:38 AM

Maybe this is a redundant question here, but unfortunately I couldn't find any concrete indications to my case. So it's concerning the typical Parent/Childs navigation and parent refreshing issue.
I have a Bean Network with one-to-many towards Subnetworks.

On Network, there is an attribute volume which value is the sum of the Subnetworks volume values.
I'd like to call my calculation-method (located in NetworkHome), so that if I edit an underlying subnetwork's volume value or add a new subnetwork with volume value, then navigate back to the parent Network, The sum will be shown on its textfield. I don't know how to solve this, for any idication I will be very thankful.

Regards

N.B.:
Currently the user must navigate back to the network list, then edit the network to see the correct sum, because I tried to solve it temporarly by putting the calculation-method inside create(), like this:

@Override
public void create() {
super.create();
sumVolumesOfSubnetworks();
}

Maybe my explanation is not really clear, so over again:
By modifying the volume value of an existing subnetwork, or adding a new underlying subnetwork with some value for volume inside a Network, I need each time when I navigate back from Subnetwork-View to Network-View, to get dynamically the calculated sum value of all underlying subnetworks. Currently I'm able to do this only if I start over again from the Network List-view, because as said I'm calling the calculation method inside create().

Please don't hesitate to post your hints. Thanks.
