These are two separate issues.
This looks like a bug which can break the android designer. It would need to be filed separately against the Android component of XVS:
> System.NullReferenceException: Object reference not set to an instance of an object.
> at Xamarin.VisualStudio.Android.CommandHandlers.GetSdkInfoCommandHandler.ConvertFramework(AndroidFramework x) in C:\d\lanes\5409\8d20b19d\source\xamarinvs\src\Core\VisualStudio.Android\CommandHandlers\GetSdkInfoCommandHandler.cs:line 43

There's an issue in inspector which could break the ios designer because it'd break events from being raised correctly:
> System.ArgumentNullException: Value cannot be null.
> Parameter name: path4
> at System.IO.Path.Combine(String path1, String path2, String path3, String path4)
> at Xamarin.VisualStudio.Inspector.XamarinInspectorPackage.<RemoteServerProvider_ServerConnected>d__19.MoveNext() in C:\d\lanes\5409\8d20b19d\source\xamarinvs\src\Features\VisualStudio.Inspector\Vsix\XamarinInspectorPackage.cs:line 158
This issue should be filed against Inspector.
The issue you're experienced in the screencast does not look like an ios designer bug. I believe the workaround I was given before is to right click on the file and choose 'open with' and then choose the ios designer. Does this fix the problem for you?
We should still file those other two issues as actual bugs as they are problems which need addressing :)
Can anyone confirm that the two issues above were filed, and also that the workaround did work? If so there are no designer bugs here, but there are issues which can negatively affect and break the designer which absolutely should be addressed!
No, the above two issues have yet to be filed. The Global Logic team has been out on holiday, and thus unable to follow up. Mohak and I discussed this a bit, and he will be filing these issues upon his return.
Just chatted to Mohak - it looks like all the files were installed but sometihng is wrong wrong.
There's nothing in the main log and there are no designer logs. We need working logging to diagnose this, or someone needs to help figure out what's going wrong.
If you look at the other log files attached there are many worrying looking exceptions which could be affecting us, such as:
System.> System.NullReferenceException: Object reference not set to an instance of an object.
> at Xamarin.Messaging.Integration.State.AgentsStartingState.ReportAgentFailure(AgentInfo agentInfo, IMessagingAnalyticsAggregator analytics, Exception ex, Nullable`1 progress) in C:\d\lanes\5409\8d20b19d\source\xamarinvs\External\messaging\src\Xamarin.Messaging.Integration\State\AgentsStartingState.cs:line 112

> Xamarin.Messaging.Integration.State.AgentsStartingState|Error|0|An error occured starting the Build 126.96.36.1996 agent: Object reference not set to an instance of an object.
That should also be filed in addition to the other two issues. For now we need more information about what's throwing the exception to properly deal with the issue.
Marking this as 'confirmed' for now. There are many worrying exceptions in the logs which could cause issues, but as of yet there is nothing specifically designer related showing up anywhere.
It is likely we will simply close this bug in the near future with no action taken on our part.
Have all the bugs which I've indicated in previous comments been filed and investigated? Some of those are blockers.
To re-iterate: There are bugs in the logs which can break the designer. They could've caused this, or it could've been something else.
There is no known action we can take on our side so once the other bugs are filed we can close this.
Thanks. I’ll just close this then.
