[Bug RHV 4.1.7] VM snapshots "clone" button doesn't work.
Last modified: 2018-04-30 14:58:19 EDT
Created attachment 1334215 [details] ui.log Description of problem: VM snapshots "clone" button doesn't work Version-Release number of selected component (if applicable): RHV 4.1.6 How reproducible: Always Steps to Reproduce: 1. Create a VM with disk. 2. Create a snapshot. 3. Select the new snapshot created. 4. Select the snapshot and click on "clone" Actual results: The rhvm portal opens the error dialog box with below message in it, ==>> Uncaught exception occurred. Please try reloading the page. Details: Exception caught: (TypeError) __gwt$exception: <skipped>: qib(...).e is null Please have your administrator check the UI logs. ==>> Expected results: The vm clone from snapshot should work using RHVM GUI. Additional info: The ui.log attached.
This regression has been introduced by https://gerrit.ovirt.org/#/c/80695/ in 4.1.6. The reason is that the CloneVmFromSnapshotModelBehavior is an ExistingVmModelBehavior but initially has the VM set to null. Hence, the isHostedEngine() code in UnitVmModel fails on NPE if the getVmConfigurationBySnapshot returns later than the AbstractVmPopupWidget.edit() gets called.
fixed on 4.2 : https://bugzilla.redhat.com/show_bug.cgi?id=1491230 (currently on QA) mark as duplicate / downport to 4.1.6 minor if needed

yes, should be an easy backport (partial pick from https://gerrit.ovirt.org/#/c/82123/)
