There are two problems however. The first is the an error related to a metadata field called qstring_validation_pattern. If I set the value to "/\d+/", it fails. I tried "\d+" but it fails again even if the qstring value is a number. If I set it to ".*" it works but I'd like to know what is wrong if I set it to \d+. The second problem is that I want to query the layer based on many attributes, not just one. If I pass in the url multiple qitem and qstring parameteres, only the last one is used.
