Filtering not working with Grails 2.2.5

[echujon]

I'm using grails 2.2.5 and easygrid 1.7.1

When I try to filter with the ~(contains), ~!( does not contain) ^(begins with), etc I get: :operator is null is filter: name

and when I do the == (equals) I get: This stacktrace: filters: {"groupOp":"AND","rules":[{"field":"name","op":"eq","data":"Children"}]} rows: 10 _search: true java.lang.Object cannot be cast to java.lang.String.
