@Command([ViewShowSearchBar]) not work in a Navigator?

In a navigator, I have a button with @Command([ViewShowSearchBar]) as the only action. In version 5 it works fine, in version 6 I get the error “Cannot execute the specified command.” If I create an action button the command works fine. Does anyone know if there is a problem with using this command in a navigator in version 6.5.2?

It only works when the db property check “Use Javascript when generating pages”
