Does not seem to work with server-side preview5 #2

Closed anddrzejb closed 5 years ago

The readme does not state if this is lib is meant only for client side or for server side as well, but the test apps have server side (even though not updated to preview4), so I assumed that was the intention. For server side, when injecting I18nText, browser returns exception:

System.InvalidOperationException: JavaScript interop calls cannot be issued at this time. This is because the component is being prerendered and the page has not yet loaded in the browser or because the circuit is currently disconnected. Components must wrap any JavaScript interop calls in conditional logic to ensure those interop calls are not attempted during prerendering or while the client is disconnected. at

Managed to get rid of the error, when turned off pre-rendering for the server side. But then the whole thing failed, because JS was never included. Just to test the language, I manually added the JS part. That seemed to work, however the published translation was not correct - it was either the field name ("AppName") or nothing at all. My json is { "AppName": "Fare Monitor" } I will try to soon (next day) prepare a repo with sample.

Thank you for your reporting!

I'm very sorry that Server-side Blazor is not supported at this time.

Before 3.0 preview, it had been works fine also Server-side Blazor, but 3.0 preview broken all of the architecture.

Off course, I'll try to fix it to works fine on Server-side Blazor, but please give me few week or months for do it.

(I appended a comment about Server-side Blazor is not supported to "readme", just now.)

Today, I supported Server-Side Blazor.
