Is wffweb suitable for a normal web development?
Yes, but for a normal website (which doesn't have a user login) it's better to use any other MVC based framework.

Is there any web ui feature that will be impossible to do with this framework?
There is nothing impossible with this framework. However, file upload and file download options should be handled in some other way (other framework/servlet) because currently it doesn't support multiplexing.
Is there any known demerits with this framework?
To gain more readability and maintenance flexibility we use anonymous class style coding in Java but sometimes it is referred to as an anti-design pattern. It has an initial first time performance impact if the tag hierarchy is heavy but it's only once in the whole life time. And also this kind of development makes a method very lengthy unless it's properly managed/modularized. But if you don't like anonymous class style coding you can follow normal object creation coding style. It's always recommended to develop reusable components which will increase the productivity & maintenance comfortability. You can also maintain separate package (.jar) for the custom components (.class files).
Kotlin solves the issue of Java anonymous class, using apply function block we can get the same readability as Java anonymous class style coding without generating anonymous class. Checkout this code from Kotlin wffweb sample project.
How wffweb is different from MVC framework?
In an MVC framework, the application is categorized in to three, i.e. Model, View and Controller. We have to write code for each part separately and need to connect each other. In wffweb, it introduces a new architecture for application called M-LT-P i.e. Model Logical-template Push. We have to write code for the Model and Logical-template only the Push is handled by the framework itself. Any changes in the server side is updated with the browser by the framework, the developer doesn't have to write any webservice, server calls etc.. he can write coding just like a client side application, eg:- swing application.
How wffweb is different from a swing application?
In a swing application, we use ready made components/listeners like
ActionListener etc.. But wffweb is a web framework so we build html
tags and attributes which can make a ui, for eg:- to show a text field we use
new Input(null, new Type(Type.TEXT)).
You can build your own components to reuse it. The events in wffweb is handled by event attributes like
which can be used to handle event either at server side, client side or both sides.
Is it possible to generate an extremely large & complicated HTML (used for reporting purpose) with
Yes, but they consume memory while generating HTML string (if the
tag hierarchy contains a deep nested tags) so if there is no enough
memory available while generate the HTML string then it might throw
an error. In such case, there are alternative methods introduced in
the latest version, they are
methods will never throw any error but may be slower than
