Variables in Widget Dynamic Configuration?

Question

I'm trying to implement a core_v2_forumLookup Property Template in a custom widget but I would like the available forums in the lookup to be scoped only to the group where the widget is placed. I saw the property parentGroupId and when I hard code that to my testing group id it works as expected in limiting the scope. However trying to get it in context using variants of $core_v2_group.Current.Id doesn't seem to be able to retrieve it. 
 So: 
 
 Are variables allowed in Dynamic Configuration templates? 
 If yes, is there a better method to get the current group id into parentGroupId than $core_v2_group.Current.Id?

While it is true that the core_v2_forumLookup property template does not support contextually filtering to a group, a new forum selection template can be created to implement the logic you want. The adjustment to your widget below adds a drop-down to select the alternate forum from the list of forums in the current group. It uses a widget-embedded property template to implement this behavior. Notice that this custom implementation uses the contextual group to list forums when it is available and will fallback to listing the first 100 forums when a group context is not available (for example, when selecting to edit a page from the page list in Manage Theme when a valid context is not available to edit the page within). Specifically: This uses the embedded selectforum-template.vm file as the template instead of core_v2_forumLookup The implementation of the forum selection in selectforum-template.vm is used to render the property UI for the forum selection configuration option and makes use of the contextual group. The selectforum-template.vm file saves the selected forum by ID directly so the check within the Content script was updated to not check against the query encoded format.
