I have a View with an associated page that has a single parameter. The param on the View is configured with a default value just by setting the value to it when it’s saved (e.g. `true`).  
The only time I want to pass this param into the URL is when it’s _not_ the default value, e.g. `false`. But when I pass in “[http://gateway/url..../false](http://gateway/url..../false)”, and then remove the false and not pass in any param value to the url, the false value still remains. I’m assuming that the value is cached… How do I stop it from caching?

i have the same problem. we have a view with database Select Query, and if i load data on the table, and then i delete that data on the database, if i refresh the perspective view, it brings all the data back on the view, even when the DB has no data on that table

I tried using a incognito in chrome to do the test but it does the same thing.

any ideas?

You can actually set the params to be non-persistent... I'm not sure if that works though. Setting them to non-persistent also kinda removes them from the view's definition... so when you reopen it in the Designer they disappear from view 🙂

Which is why you should always use `coalesce()` with such properties/params.
