@phillipskevin
so I’m still a little confused
when you notice the delay, what are you expecting to change?
Christopher Oliphant
@RALifeCoach
nothing
Kevin Phillips
@phillipskevin
so… you click a button and expect new data to be shown, but it takes time
Christopher Oliphant
@RALifeCoach
It is actually a very long and complicated page load - the data is loaded once and then reloaded with more details
Kevin Phillips
@phillipskevin
ok
so you’re expecting the entire screen to change?
Christopher Oliphant
@RALifeCoach
I have added the timing code to find out why those two steps were taking so long
I can’t do anything to reduce the initial load
That’s why I am now focusing on the reload
Kevin Phillips
@phillipskevin
sure
Christopher Oliphant
@RALifeCoach
Justin suggested lazy map and I was seeing timings where I wanted them to be
But lazy map is broken with more complex data
I was really hoping someone would fix lazy map
Kevin Phillips
@phillipskevin
is there an open issue?
Christopher Oliphant
@RALifeCoach
yes
Kevin Phillips
@phillipskevin
about LazyMap I mean
Christopher Oliphant
@RALifeCoach
canjs/can-map-lazy#1
Kevin Phillips
@phillipskevin
thanks
Christopher Oliphant
@RALifeCoach
Do you have any new suggestions? Can you schedule a fix to lazy map?
Kevin Phillips
@phillipskevin
if it’s not a DOM update that is causing the problem (which you ruled out using paint flashes) I don’t have any new suggestions right now
Christopher Oliphant
@RALifeCoach
and lazy map?
Kevin Phillips
@phillipskevin
I can take a look at LazyMap
but I can’t promise anything
Christopher Oliphant
@RALifeCoach
it is simple to re-create
Kevin Phillips
@phillipskevin
ok, if you can track down the exception, PRs are always welcome
Christopher Oliphant
@RALifeCoach
I found the exception, but I just don’t know the code well enough to to create a PR

                            }
                        });
                    } else {
                        var reference = newChild._nestedReference.make(newChildPath);
                        if (self._bindings) {
                            bubble.add(oldChild, newChild, reference());
                        }
                    }
                }

            if (setNewChild) {
                setNewChild();
            }
the line throwing the exception is oldChild._nestedReference.each(_nestedReference is null
oldChild is not a type Constructor, but an Object
Kevin Phillips
@phillipskevin
ok
Christopher Oliphant
@RALifeCoach
@phillipskevin do you have an estimate as to when you can have a look?
Kevin Phillips
@phillipskevin
I am traveling at a client this week so not really.
I’m going to look at the issue today, but don’t have any idea if I’ll know how to fix it.
Julian
@pYr0x
@RALifeCoach can you reproduce this issue with lazymap on a simple and short example
Christopher Oliphant
@RALifeCoach
I knew someone was going to ask that. Yes I can.
Julian
@pYr0x
;) we have to make tests for CI
so a test that reproduce this problem is the first step to fix this
btw. can-map-lazy is currently for canjs 3.0
not for 2.x
Kevin Phillips
@phillipskevin
thanks, I was trying to figure that out
Christopher Oliphant
@RALifeCoach
I know it’s scheduled for 3.0, but gave me the best performance improvement so far
Kevin Phillips
@phillipskevin
require(‘can/map/lazy'); without installing can-map-lazy
there is a can.LazyMap plugin for 2.x also
right @pYr0x ?
Julian
@pYr0x
lazymap is currently (in canjs 2.x) integrated.
if i understand right, you have problems with nested properties?
