Thanks.

Hi,

For the second one I added extra checks to NoesisNotifyArrayPropertyChanged last week. Could you try with the latest code from the master branch? The problem I fixed was a null pointer in that function, but it looks like your crash is not there. Still worth a try.

The other one looks trickier to debug without your assets. Would you mind sharing your project with us?

Next time either of them happens, could you please create a mini dump, open a ticket in our bug tracker and attach it?

Thank you very much.

Hi,
the NoesisNotifyArrayPropertyChanged(Object, propertyName) seemed not work if the array is defined in C++(with UPROPERTY), instead of Blueprint

I just tested it and it seems to work for me. With the code before my last commit it crashed if the name wasn't the name of a valid property. With the latest code it doesn't crash.

That stack looks too deep to be a problem with NoesisNotifyArrayPropertyChanged. Could you create a crash dump? You can do it from Visual Studio, in the debug Menu, once the game has crashed.

Thank you,

Hi ride_wind,

A bug was recently discovered that could be causing both those crashes. When you run that XAML, could you take a look at the Output Log window and see if there's a warning from Noesis that reads: "Only EventTriggers are allowed in FrameworkElement.Triggers"?

If you find that, it means you've tried to use a Trigger other than EventTrigger for the Triggers property of one of your elements. It is not supported, and there's currently a bug that could cause crashes similar to yours. In that case, could you remove the Trigger causing that warning and try to reproduce the crash again?

We will fix the bug so it doesn't crash even if the Trigger is there, but that should fix your problem for now.

Hi hcpizzi,

I don't see this warning : "Only EventTriggers are allowed in FrameworkElement.Triggers" , in my project, but it has other warning before.
But now I fixed code , there has not warning and those two crashes don't exist.

There has another callstack in Android platform about notifychanged crash,
hope it can help you.

Hi,
Maybe NotifyArrayChanged has bug.
I just make little modify to tge QuestLog sample, put the VM to C++

struct FQuest
{
title
image
description
}

class QuestLogVM
{
array<FQuest> Quests;
//this is new question, how to binding selectedItem to this?
FQuest SelectedQuest;
}

the 2 c++ class works well when I call NotifyArrayChanged(vm, Quests) in blueprint graph

however, I create a blueprint class inheriented from QuestLogVM, then the NotifyArrayChanged does not work

and seemed there is memory problem in NotifyArrayChnaged()
QQ图片20180412134413.png
if I break the NotifyArrayChanged node, the ram used by UE4 remains unchanged, while I link the node , the used ram seemed crazy increase.
