Check permission for a specific user

Hello @tdixit 

this is what I'm doing ... checking Visibility permissions set directly on the entity, unfortunately this method does not consider the "collection" permissions.

The article is referred to thingworx 7.0 ... strange on version 8.5 or 9+ this is still not possible.

I found now that there is a service on CollectionFunctions -> CheckPermissionForUser 

but it returns a boolean, and is not clear the function of parameters 

// result: BOOLEAN
var result = Resources["CollectionFunctions"].CheckPermissionForUser({
	name: undefined /* STRING */,
	type: undefined /* STRING */,
	user: undefined /* USERNAME */
});

May be "name" is entity name , and "type" is the specific permission to check (visibility ... runtume execution...) ?

The service never gives error codes...

I can't use 

Resources["CollectionFunctions"].CheckPermissionForUser

always returns false, and never gives errors (also with bad parameters)

Can someone give a working example ? 

I have Thingworx 8.5 SP9
