Change subject: webadmin: StorageModel NPE (#822459) ...................................................................... webadmin: StorageModel NPE (#822459) https://bugzilla.redhat.com/822459 Have a data center "Defaul (NFS, V1)" which can import NO storage, than: 1. open WebAdmin, switch to Storage main tab 2: click Import Domain - immediately a NPE mentioned above is thrown 3: switch Data Center to "(none)" 4: both "Domain Function / Storage Type" and "Use Host" are correctly filled 5: let in "Domain Function / Storage Type" selected for example on "Export/NFS" 6: switch the "Data Center" back to "Defaul (NFS, V1)" 7: the gui will show the same filled in "Domain Function / Storage Type" as was for "(none)" ("Export/NFS" in this case). There were more problems. - StorageModel.DataCenter_SelectedItemChanged() called in row the following methods: - UpdateItemsAvailability - UpdateFormat - UpdateHost Where the UpdateItemsAvailability after some returns from server calls prepared the selectedItem on the model, and UpdateHost (again after some server calls) used it. It was basically random if the selected item will be prepared when the UpdateHost will need it. Fixed by moving the call to UpdateFormat and UpdateHost to StorageModelBehavior.OnStorageModelUpdated() to call them only after the selectedItem will be prepared. - The value NULL for selected storage domain is valid. To let the code deal with it correctly, added some null checks, othervise it fails on NPE. - Added resetting of the selected host and selected item to prevent the remembering of the old value when there is no new value to select.
