Problem with grid grouping

[syno2flickr]

Hello,

I found a bug in the class ParametersResolver (line 575).
The condition:
key.equals("group") && value != null && value instanceof List
returns always false because value is a Map (a LinkedHashMap) and not a List.

Nice catch. Thanks for reporting the error.

This is an array in Ext JS 4, but in 5 and 6 it is an object

4: group: [{property: "cuisine", direction: "ASC"}]

5 + 6: group:{property: "cuisine", direction: "ASC"}
