Link to minimal reproduction or a simple code snippet

I found this error here when testing my abp.io UI (happens when clicking the "features" on a tenant https://localhost:44307/saas/host/tenants)

Is this an issue on your side or abp.io's?

@sturlath I honestly can't tell. Not an error I've seen before : Unable to evaluate index expressions of type 'PropertyExpression' and no similar complaints for our Blazorise.Select yet.

Are they perhaps doing dynamic stuff? Can we get the code snippet for how the Blazorise.Select is being used / whatever it's being executed?

https://github.com/dotnet/aspnetcore/issues/56145 I found this very recent issue about using Dictionaries...?

That functionality is in their pro version and I domt have the source for that. I pinged them on the ticket. Lets hope they answer.. else I will need to back down versions of Blazorise 😖

@David-Moreira abp.io points to this dropdown item opening this modal here https://github.com/abpframework/abp/tree/dev/modules/feature-management/src/Volo.Abp.FeatureManagement.Blazor/Components

Is there something in there that is causing this error (or is it the dropdown it self? Other dropdown items seem to be working fine.

Well I can see the usage of Dictionaries just like we mentioned image image

This is a Blazor limitation:

PS: I suspect the limitation is specifically when internally Blazor tries to bind the SelectedValueExpression part automatically. So it might work by just using the SelectedValue and SelectedValueChanged parameters separatedly, if the SelectedValueExpression part is not needed. (The expression parameter is usually used for validation purposes as far as I personally know.)
