So, actually there was a bug, but it only happened when you destroy something that was still processing events. In this case, you click a button and that removes a view that contains it, so that exposed this 2 part issue. First was a bug in haxui-core and second was in hxWidgets. These should be fixed now - so you’ll need git versions of each lib (lemme know if you dont know how to do that)
All in all a great find!
Cheers!
Ian
Great, happy to have sort of help haxeui.
I’ll try to find again how to set a git/dev haxelib.
I did it years ago, it should come back 
May I open a new post for more question or should I edit this one?
New threads might be easier - just for context
Ian
it seems that the crash which occurs when I remove a component is back.
But it’s not the same because it’s harder to reproduce…
still a segfault 11, but only on some cases.
I suspect it related to garbage collector because I do something like
currentComponent = new myBox1();
currentComponent.registerEvent(xxxx, onevent);
addComponent(currentComponent);
onEvent(e)
removeComponent(currentComponent)
currentComponent.unregisterEvents();
currentComponent = null;
currentComponent = new myBox2();
addComponent(currentComponent);
=> segFault11 on refresh screen
How could I debug my code > haxeui-core > native backend so I could point on the issue ?
The best bet is to just try and reduce it to a super minimal example, then you can try and find what is the cause (or i can)… Its a lot of trial and error
You can use VSCode i think to debug hxcpp, but ive never had much luck with it (though i havent tried in a while).
Let me know if you manage to create a super minimal example.
Cheers,
Ian
I found the culprit : ListView.
It crashes if the component you want to remove include a listview
You can see it on https://bitbucket.org/WillNa/haxeui-bugs/, bug 2 and 8
(for HXCPP debug, I tried hard for 2hours without success…currently looking for more details on vscode .json file, I don’t understand how task and launch works together)
Still trying to find the root cause.
I was finally able to get more than a poor ‘segment fault : 11’ on terminal.
Again related to event, but I need to find more to be able to share a minimal example to produce the crash
I found it to crash if I have 42 components or more on a vbox
At 41, it no longer crashes…
I still need to understand if it’s because of the height of stage or the number of components…
Simple exemple to reproduce crash coming soon.
EDIT : no problem on a basic sample…I need to find what happen first on my app which make the 42th component crashed the app. It’s not related to number of components but a memory error probably. Definitely related to event+rev, but I don’t know how exactly for now.
App no longer crashes if I comment a line in Component.hx
if (dispose == true) {
child._isDisposed = true;
//child.removeAllComponents(true);
child.unregisterEvents();
child.destroyComponent();
}
so I assume one child is the culprit, but whatever I did, it’s when I add any more component that it crashes.
It drives me insane!
EDIT : replaced with
child.removeAllComponents(false);
same crash
So I rebuilded my project with -debug and the crash is different
Unhandled unknown exception; terminating the application.
Abort trap: 6
I still don’t see why…
I tried to load the Component that crash on startup
app.ready(function() {
app.addComponent( new CrashingView() );
app.start();
});
no problem!!!
So it comes from what happen BEFORE I load it
Can you attache a test app?
EDIT: ah, bugs 2 & 8 correct?
Cheers,
Ian
unfortunately no.
I’m unable to create a test app, while, trust me, I tried!
It only crashes on my case, so I’ll try to anonymize (NDA product so 
) part of my app which crashes
EDIT : so I did it…it crashes on my app, it doesn’t on my bugssample app
I made it!!!
I made it crashes::
It’s the first time in ages I’m happy to (re)produce a crash!
What is VERY strange is the crash occurs only if my component is the first added to the HaxeUIApp.
Please look for comment added on Main.hx
https://bitbucket.org/WillNa/haxeui-bugs (bug10)
Great! Thanks, ill be looking at these issues “soon” (other things keep coming up)… but thanks for the repro!
Cheers,
Ian
I really hope you’ll be able to fix (the error or my stupidity)
This one locks my current project 
I really cant seem to follow what #10 is trying to do… I there any chance you could try and put the issue into a totally separate project - it seems to have components over components (wxWidgets doesnt like overlapping components) and seems to do some other things that im just not understanding - or even understanding what you are trying to do
Ian
PS: you might want to join the #haxe discourse too (https://discord.gg/c5QRwm) - will be easier to chat there - up to you though of course.
yes, it seems you got it.
I want change current view by a new one, not using tabs
intro -> create -> edit -> end -> intro
But you added a theContainer, why is it needed ? it’s a view in a box into a vbox…?
EDIT : to be sure, I did the same and…crashes . so adding another layer didn’t fix it
Does the sample i attached crash also? Can you try and make that sample crash in the same manner? (with minimal code).
The reason i used theContainer is because that is a child of the main view, so i can add buttons and other controls in the main view.
Thanks again!
Hi,
The sample doesn’t crash : not enough component on screen…
The sample updated , which crash, is available here
https://filebin.net/odshbn5ofmfisgc3
remove some components on second.xml (42 in my case) and it will no longer crash
