can I make the model condition Id = (param) id" filterable default on?"

This probably isn’t a great idea for lots of reasons I haven’t yet considered, but I’m working on a proof of concept whereby you could switch between different records on a detail page without doing a hard page refresh. The idea is to make pulling up data from a new records as fast as dumping and loading a model, removing the excess delay from a total page refresh. 

Everything is working, EXCEPT, when I put on my main Opportunity model condition Id = (param) id a “Filterable Default On” setting, it does not load the right Opportunity on the first page load, as if the condition is filterable default off. 


For more details - I’ve got an Opportunity detail with a dozen other related models. The page is a child page. On the master page there’s a Recently Viewed navigation button that opens a popup and shows several other opportunities. You can click on one and it reloads the page, fine. But I want a row action that simply dumps the model in the background, and loads the model for the selected row, which is so much faster. 

I’ve got a row action that deactivates my id = param id condition, activates and sets my id = single specified value {{{Id}}}, and reloads the model. Works great, but that first load is still some random opportunity. 

Is this a bug? Or a known limitation of page param conditions to prevent nuts like me completely messing up a page?
