We recently upgraded from Bootstrap 4 to Bootstrap 5 in our DotVVM application. After making this change and updating our configuration using:
config.AddBootstrap5Configuration();
we started encountering the following error:
Attribute value of type 'CommandBindingExpression<Delegate>' is not supported.
Please convert the value to string, e.g., by using ToString().
This issue did not occur when using Bootstrap 4, and it only started after switching to Bootstrap 5. It seems that some DotVVM bindings, particularly command bindings, are no longer being recognized correctly when used in attributes.
Could you provide guidance on whether this is a known issue with the Bootstrap 5 configuration in DotVVM? Additionally, is there a recommended approach to resolve this without having to refactor existing bindings?
Any insights would be greatly appreciated.
Thank you.
