Merge Server-Client Errors:

[andrewnordlund]

On https://wet-boew.github.io/wet-boew/demos/formvalid/formvalid-server-en.html there are .NET examples of server-side validation with WET.

Are there any Java examples?

I was able to get it work. It was ages ago, but see #8275 (comment).

@andrewnordlund not that I am aware but you should be able to do your own java implementation by following the .net server component example here: https://github.com/wet-boew/asp.net-formvalid-serverside

The problem here is that .NET is a wildly different beast than well.......just about every other back-end language/framework out there.

https://wet-boew.github.io/v4.0-ci/docs/ref/formvalid/formvalid-en.html, for example, says for .NET, put this in your code:
<asp:CustomValidator ID="TypeOfPrestationCv" ErrorMessage = "Your server error message" ControlToValidate="TypeOfPrestation" OnServerValidate="TypeOfPrestationCvServer" Display="Dynamic" EnableClientScript="false" Cssclass="label label-danger wb-server-error" runat="server"></asp:CustomValidator>

That doesn't tell me how to implement that in any other language/framework.

I have clients not using WET validation in Java because of of things like this. So they end up writing their own validation and bypassing WET validation entirely, which often introduces accessibility issues. I ask them to use WET validation. They ask how to do it in Java. And I don't know what to tell them.

We have same problems in CRA, where most of the applications running in struts(JAVA framework).

And .NET WebForms (that has the working example) is wildly different from .NET Core (now .NET 5), and the same question has come up in #8581.

@mingjiongliao JAVA the simple solution works no problem.
