Reads settings correctly, making changes and submitting yields no changes.

These can probably be removed as they provide the same functionality as Configuration > Manage Active Server Components > Edit.

This is totally different from Manage Active Server Components.

This is for configuration of VHosts, so you can change settings for each domain, while Manage Active Server Components is responsible for enabling/disabling Tigase XMPP Server component like MUC, PubSub, etc. at runtime.

I tried to use it and change was applied properly.

Works OK, able to read and manipulate vhost items.
