camunda Filter Service

CreateFilter.java

// create a taskQuery
TaskQuery myTasksQuery = taskService.createTaskQuery().taskAssignee("daniel.meyer").active();

// save taskQuery as filter
Filter myTasksFilter = filterService.newTaskFilter("My Tasks");
myTasksFilter.setOwner("daniel.meyer");
myTasksFilter.setQuery(myTasksQuery);
String filterId = filterService.saveFilter(myTasksFilter);

// execute the filter
List<Task> tasks = filterService.listPage(filterId, 0, 20);

Perhaps the line 8 was:
String filterId = filterSvc.saveFilter(myTasksFilter).getId();
