[HotReload]: An item with the same key has already been added. Key: CommonStates

Hello, An error in the title happens on some of my pages. I think it might be related to the fact that I use this in my page:

                                <VisualStateManager.VisualStateGroups>
                                    <VisualStateGroup Name="CommonStates">
                                        <VisualState Name="Selected">
                                            <VisualState.Setters>
                                                <Setter Property="BackgroundColor" Value="Transparent" />
                                            </VisualState.Setters>
                                        </VisualState>
                                    </VisualStateGroup>

Hi, can you try to change this code to:

<VisualStateManager.VisualStateGroups>
    <VisualStateGroupList> <!-- add this -->
        <VisualStateGroup Name="CommonStates">
            <VisualState Name="Selected">
                <VisualState.Setters>
                    <Setter Property="BackgroundColor" Value="Transparent" />
                </VisualState.Setters>
            </VisualState>
         </VisualStateGroup>
    </VisualStateGroupList> <!-- add this -->
</VisualStateManager.VisualStateGroups>

I can't even run the app without it.

Hello, I still get an error. To give you idea what I'm doing:

                <CollectionView
                    BackgroundColor="Transparent"
                    HeightRequest="120"

                    </CollectionView.ItemTemplate>
                </CollectionView>

It happens when trying to save and hot reload of course.

I still can't reproduce it ( .NET Meteor version: 5.2.5 Workloads: maui 9.0.0-preview.5.24307.10/9.0.100-preview.5

https://github.com/user-attachments/assets/ad8764b1-e988-4f8f-9981-4e87952c09f4

I attached this example: MyExample.zip

[ziomek64]

Not sure what's going on, should I give whole page? It happens only on the one when I have these. I'm using stable .net 8 latest one

[JaneySprings]

Have you been able to reproduce this problem on the project that I sent to you?

Sorry I haven't seen it, but to be honest no. I wasn't able to reproduce it. I had to modify csproj a bit, add android sdk and jdk directories, remove all platforms except android. Not that it makes a difference I think

What should I provide you from my project? It's too big and unnecessary to give you the whole thing, so whole page?

[JaneySprings]

Can you extract this problem page in the separate working project (to reproduce the problem)? You can remove all of your data and replace it to simple strings.

I actually don't know what's going on. I've completely re-implemented this page to be standalone but I'm just not running into it. I will attach it but I don't know to be honest. Is there any way I can check exactly what's going on but in my full project?

I think you can try to disable (comment) some parts of your application and check the result.

I'll try to investigate in free time, but could be hard to find.

Is this a bug in meteor? Any other hot reloads work.

[JaneySprings]

Maybe... but I can't reproduce it. If this is not an important issue for you (if you can comment VisualStateManager temporary), you can close this issue and don't waste your time =)

It is working now, which is honestly weird why. I don't even want to know why. If I stumble across the reason I will drop it here
