This seems like it should be doable but for the life of me I can't figure it out.
I am trying to pass an NID from one pane to another on a front page using page manager and panels for layout. Specifically, there is a node in a Feature Box on the front page of the site that the client can populate by adding a node to a nodequeue. That nodequeue can accept several differnet content types: Lets say Events and Articles can be added to the queue.
There is also another pane on the front page which has a view "Next Event". So the next event will automatically appear in that panel.
There are times the client would like to promote an event by putting it in the feature box pane. If the client does that, I would like to pass the NID from that node to the Next Event view to hide it.
You can see what I DON'T want at the site itself, which is live as of the date of this post: http://chathamnjhistoricalsociety.org. There is an event featured, and then at the bottom of the right sidebar the same event is displayed.
I am aware of the "reverse" setting for a contextual filter, so that's not a problem. I am thinking that I can supply the node NID from the Feature Pane to the Next Event pane with a token. I feel like the answer is staring me in the face but I just can't see it. I tried to find a way to provide a context that pulls in tokens as part of the page manager regimen, but can't seem to find a way to pull in a context from a particular panel. I have Googled around and can't seem to find a tutorial addressing this scenario.
Maybe I'm just going about it all wrong, but the contextual filter seems the way to go.
If anyone out ther has a recipe for this I would greatly appreciate it. I've been at this for hours and have exhausted all Google search strings.
I have also cross-posted this on the Google+ community: https://plus.google.com/+RobertKopacz/posts/NuvWAyXCeTQ

Let's see if I understand this correctly. http://chathamnjhistoricalsociety.org/content/chatham-historical-society... is not a node page. If it were, excluding it from the Next Event view block would be done with a contextual filter. You need to exclude the node id that's in the panel from the Next Event view block. Correct?
Seems like that should be doable in the view.
Hi Eric! Well, I actually
Hi Eric! Well, I actually came up with another way, that does not require a contextual filter. You can put a regular filter on the Events view in that right sidebar, to filter out of the view any nodes which are in the nodequeue, and that worked. I was overthinking the problem.
However, I still think there should be a way to do it as a contextual filter, by passing the argument from a node resident in one pane to another.
I think you might be able to do something like this with Panelizer, but Panelizer is limited to overriding node pages, and does not work for custom pages.
So even though I solved my immediate problem, I continue my hunt for an answer as to whether this is possible.
