Export Appliance Dialog does not export selected machine if machine state is changed

[jami]

This is a behaviour report that might be used to correct the usabillity. I ran into the following scenario:

1. I started (accidently) my centos host
2. I open the dialog export appliance
3. I see that i cant export a running machine (its ok). The running machine is disabled in the select box. So far so good. I left this export selection dialog open!
4. I shutdown the running host
5. The formerly running machine is now selectable. So i select it.
6. I press export. The default export filename is right. Then the strange thing happend. The Appliance export starts to export the machine next to the one i want

Long story made short: Start a host from a list with at least 2 hosts. Open the export dialog Stop the host and select it at the exporter dialog Export the host. It will export the wrong host

I have 4 host machines (3 x centos, 1 x windows)
