Hi,
When selecting equal as the condition for remote filtering, a checkbox list appears. When you choose a option, the filtering throws and error:'Type 'System.String' is not supported for deserialization of an array.'
Below is the JSON passed
{"mode":"AND","data":[{"dataIndx":"EmployeeName","dataType":"string","value":["Callahan"],"condition":"equal"}]}
I tested this on your demos and it seems to be broken as well.
Can you review and see if there is a bug here and if so, is there a way to remove the equals option in the condition dropdown?
