This page lists the tasks the Wicket team agreed to implement for Wicket 7.0.

Ideas for Wicket 7.0 list some more ideas but to add a task in the Roadmap it has to be discussed first in the dev mailing list. Ideas with attached patch in Jira ticket or Pull Request have a bigger chance to be included in the Roadmap.

How to help us

  • Pick a task from this wiki page or from Jira with "Fix Version" = 7.0.
  • Implement it (+ tests when possible) and make a Pull Request at GitHub (apache/wicket). We do not own the GitHub repo but it is easy to pull from your repos and apply the code. It is also easy to make code reviews and comment.
    If there is no ticket in Jira for an entry in the Roadmap please create one. Always add a comment to the ticket in Jira when you start on it. Just to prevent two or more people working on the same thing.
  • Add an entry to the Migration page with description of the change and short code sample of the old way and the new way of doing something.

Java 7 as a minimum

Java 7 has nice support for generics, better annotations, and Java 6 is reaching its end of life pretty soon.

Jira:

Generics for org.apache.wicket.Component

Using Java 7 will allow to use the "diamonds operator", i.e.

MyPage.java
  Component<Entity> c = new SomeComponent<>("id", model);

Servlet 3 as a minimum

While we opted to not require servlet 3 for wicket 6, it has bitten us a couple of times solving issues in wicket 6. Servlet 3 has been out for ages, so we should move with the times.

Minor API cleanups

API Tweaks

SimpleFormComponentLabel should output the "required" class just like wicket:for

ajaxbehavior#updateAjaxAttributes() should get component passed in

otherwise referencing the component as needed in throttle settings is annoying

queryField.add(new AjaxFormComponentUpdatingBehavior("onkeydown") {
	protected void updateAjaxAttributes(AjaxRequestAttributes attributes) {
		attributes.setThrottlingSettings(new ThrottlingSettings(queryField.getMarkupId(), Duration.seconds(1)));
----------------------------------------------------------------------------^

throttling settings should be mutable to make it easier to override just the duration without having to figure out an id

JavaScriptResourceReference#getDependencies() should return an appendable List

so we can do

class MyReference extends JavascriptReference {
  getDependencies() { List<?> list=super.getDependencies(); list.add(...); return list; }
}

XyzValidator#decorate() should work with IValidationError instead of ValidationError

Refactor checkgroup/radiogroup to make them non-components.

  • it is awkward to require a parent container as a wicket component. most of the time it needs to be attached to wicket:container tag because there is no reason to have an actual parent tag or a parent tag is impossible (in case of trs, lis, etc)
  • having groups as non-components will allow for nested sets of checks and radios
  • having groups as non-components will allow for disjointed sets of checks and radios in a cleaner fashion

cdi 1.1 upgrade

wicket-cdi should use cdi 1.1 which should remove dependency onto seam-conversation module.

  • No labels
