Code review comment for lp:~pkunal-parmar/ubuntu-calendar-app/CalManagement

I modified the code, now after changing the filter, calendar does not freeze.

But It looks like when I am trying to create UnionFilter with DetailFieldFilter and CollectionFilter,
CollectionFilter does not work.

3 + filter: UnionFilter {
524 + filters: [ collectionFilter /*,eventFilter ,eventOccurenceFilter*/ ]
525 + }
