dtappe Hi! Thanks for the feedback and new demo.
I tested my changes against my demo scenes and didn't notice issues. Now bugs and edge cases will always happen so that's why I opened this support forum and try to fix bugs as quick as possible.

Switching the refresh mode to manual on sub containers is a new feature to cascade the Resize() from parent to sub containers as you suggested.

I will look into your demo asap.
thanks!

ok so it turns out that this was causing the issue:

            ResponsiveContainer parentRC = transform.parent.GetComponent<ResponsiveContainer>();
            if (parentRC != null)
            {
                refreshType = RefreshType.Manual;
            }

Anthony,
I figured that was an issue. Seemed like changing to "Manual" mode behavior should be more of a run time thing and not changing actual configuration. For me, "Manual" should mean that the user is responsible for calling Resize, not some other mode.

Also FYI, on the above video, the button text is also not showing for the blue button. I believe this is also a responsive UI issue.

Sorry for the late response, I somehow missed your post notification.

dtappe, For the missing text for the blue button, I have also seen similar behavior when the prefab instance in the Canvas structure had NaN values saved and was fixed by just reverting all overrides.

dtappe the strange thing is that if you click on "cancel" the Directory object gets activated back, and there is no NaN value in the button text transform.
Only after the progress bar has completed, the same ToggleProcessingContainer() function is called and only then you get the NaNs

Anthony I read a thread where people are having the same NaNs using Unity's layout components, so it might just be a bug on their end. I'm still investigating

Anthony I'm not seeing NaN's anymore since I:

• Fixed divide by 0 and negative value issues with CalculateSpaceBetweenItemsY, CalculateSpaceBetweenItemsX, CalculateFlexibleItemSpaceX, and CalculateFlexibleItemSpaceY.
• Stopped mixing Responsive components with Layout groups and Rect Transform STRETCH.
• Reverted all overrides on Canvas prefab instances.

I have stopped using OnChange for now, but I can send you what I have changed based off v1.0.3, if you tell me where to send it.

dtappe you're the man! Indeed I completely forgot that /0 you found.
I fixed it on my side now and will publish an update asap.

Thanks again for your help, I was looking in the wrong direction.

Anthony OK. Just let me know if you want to see my changes. There was more than just the /0. I also added a simple hash return to GetChildrenFirstDepth, so that if one child was hidden and another made visible, thus the same childe count, but different children, could be detected to do a forced resize.

dtappe that's a good point, especially if the two children don't have the same "responsive item" settings. Can you send me your changes by email at contact at exoa.fr ? I will have a look. Thanks
