Viewing settings view causes null reference exception

[shadeon]

Issue

When clicking on the settings view under Management Packs (community) the error message below is shown:

This is then followed by a JIT exception (below). Clicking continue allows the SCOM console to continue functioning, clicking quit causes it to crash.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.

A new test build has been created that should resolve this issue.

In addition to the updated error handling settings for a proxy can be configured via 3 registry keys. A final key configures a direct URL to be used for connection to GitHub, without the use of the MPCatalog.net redirect.

The keys can be seen in my branch at: https://github.com/MPCatalog/scom-community-catalog-ui/blob/work/1.0.2.x-bug-fixes/Community.ManagementPackCatalog.UI/Models/GitHubRepository.cs#L114

Proxy configuration has a key for each of the following:

• proxyAddress
• proxyUserName
• proxyPassword

Repo URL configuration has a single key of:

• GitHubRepoBase

The updated version of the pack can be found here:
Community.ManagementPackCatalog.zip

Both registry configuration examples are available here:
