Error trace in the jasperserver.log file:

Caused by: java.lang.IllegalStateException: Processor of type com.jaspersoft.jasperserver.inputcontrols.cascade.handlers.converters.DataConverter for class java.util.Arrays$ArrayList not configured

Resolution:

If the Adhoc view is created on the topic type of domain, then it is embedded in the dashboard. The above issue occurs with the Adhoc view and in the dashboard. 
If you are using the jrxml type of topic and you create an ad-hoc view on top of it. You need to change the multi-select input control class from the string to the collection.
then republish the report again on the jasperserver. Then, you need to edit the multi-select input control from the jasperserver side just to check and the issue will get resolved.
