ParentId filter is not working in Group API

Question

Hi All, 
 when I am running below code data is not coming only on the basis of userId but not on parentGroupId 
 #set($query = "%{SortBy = 'LastUpdate',SortOrder = 'Descending' ,ParentGroupId=157,UserId = $core_v2_user.Accessing.Id,GroupTypes='all'}") #set($groupList = $core_v2_group.List($query)) 
 ParentGroupId 157 contains only 4 subgroups and $core_v2_user.Accessing.Id is the members of total 20 groups/subgroups. 
 for ParentGroupId 157 ,$core_v2_user.Accessing.Id is only the member of 2 groups out of 4 groups. 
 
 so as per the above code logic there should came only 2 groups in result set but I am getting all 20 records why? 
 
 please let me know the appropriate suggestion.

It appears that when UserId is supplied the ParentGroupId parameter is not used. In order to make this work as you expect, you will need to get the list of groups first (without supplying UserId ) and then on a second request pass the list of groups to the ContainerIds parameter and supply both the UserId and Permission parameter on that request.
