-------------------------------------

             Summary: listInstances : numResults query param is ignored when start and end params are not specified. 
                 Key: FALCON-1244
                 URL: https://issues.apache.org/jira/browse/FALCON-1244
             Project: Falcon
          Issue Type: Bug
          Components: webapp
            Reporter: Balu Vellanki
            Assignee: Balu Vellanki
            Priority: Critical
             Fix For: 0.7


Reported by [~pisaychuk]. 

We should use numResults if want to get number of instances different from default (10). But we can't use it without start/end params. For example.
If I have a process

{code}
and I try to get all instances with request
http://192.168.56.111:15000/api/instance/list/process/ListProcessInstancesTest--agregator-coord16-29e9fec6?numResults=12&user.name=fertrist. But it returns me only 10 most recent instances, as if it were default numResults. 
To get all instances I have to use 
http://192.168.56.111:15000/api/instance/list/process/ListProcessInstancesTest--agregator-coord16-29e9fec6?start=2015-05-18T15:39Z&end=2015-05-18T16:39Z&numResults=12&user.name=fertrist.

Is it intended? If yes, then we need to update a documentation.
Failing tests: ListProcessInstancesTest.
