Hi Joseph,
Thanks, that's what I suspected. Works like a charm now.

Bela, the issue is that AlertDefinitionCriteria was mapping that
filter field to a String type, but it actually refers to an Integer in
the underlying data model. This issue was documented here[1] and I've
already pushed a fix to master (git hash
303467aeda8d90b48cb68581d53211c774a82fd5). Thanks for finding this.

(AlertDefinitionCriteria throws ClassCastException if
filterAlertTemplateParentId / filterAlertTemplateResourceTypeId is set)
