NESPER 4.5 or 4.5.2 bug or change, nested events does not match if nested map in filt

I'm currently working with nesper. I have problem with filtering by praporty-map. for example
Expand|Select|Wrap|Line Numbers
  1. select *
  2. From Event(nestedMap('KeyName')!=null)
The Event Object for it
Expand|Select|Wrap|Line Numbers
  1. Event obj= new Event();
  2. obj.someAttributen="bla";
  3. obj.nestedMap= new System.Collections.Generic.Dictionary<string, Item>();
  4.  
  5. obj.nestedMap.add('KeyName', item)
  6.  
  7. sendEvent(obj);
This Problem is found only in last versions of nesper but it works fine in 4.1 version. I hope someone had already something like this. I dont know if they just changed it so that nested maps do not work in filtering section or it just a bug.

Additional info. EPL creates with no problem but it looks that filtering section does not get evaluated and no event matches

Omg, finaly solved the problem was that there were some changes towards sql standart, so that comparison for values which can be null shoudnt be in form 'obj!=null' but more like 'obj is not null'
