ViewCaching and $view_parameters

Next topic

Author	Message
Michael Enger	Friday 24 June 2011 2:03:15 am I've created a custom layout for handling AJAX requests which fetches content based on passed view parameters, but when ViewCaching is enabled the $view_parameters array only contains content the first time the layout is shown. I call the address example.com/layout/set/ajax/(node_id)/155 and use the attribute operator to print out the contents of the $view_parameters array to test it, and it's clearly empty after the first time. I tried using a cache-block with the $view_parameters area as keys, but that doesn't help since the array becomes empty and using a static value for keys would mean that it will show the same content no matter what view parameters are sent to it. I also tried to set the cache_ttl variable to 0, but to no avail.
