Failed to edit management networks when management network is over a vlan
Last modified: 2016-02-10 14:56:17 EST
Description of problem:
On cluster 3.0, the 'Edit management network' dialouge will fail to open properly (no 'ok' nor 'cancel' buttons), if the management network is on top of a vlan.
Steps to Reproduce:
1. Add a Host to cluster 3.0.
2. Set the management network on top of a VLAN.
3. Select the management network and click on 'Edit management network'.
The 'Edit management network' dialouge is not opened completely (no 'ok' nor 'cancel' buttons)
'Edit management network' dialouge should be opened properly
Debugging the gwt shows that HostInterfaceListModel.GetInterfaceOptionsForEditNetwork tries to access the engien side to query for the vlan parent interface.
It uses the DataProvider.GetVlanParentInterface for it, while this code isn't supposed to be supported and should have been converted to AsyncDataProvider.
There for the reture value of that query is null and a NPE is thrown on webadmin side, causing the dialouge not to open as expected.
fixed in commit bbd63c07af7d55e5d478594625f14ced908b4dd5
