Product Overview

Simply Java

ZK is renowned for its "Ajax without JavaScript" approach since 2005, enabling developers to build rich internet applications transparently without any knowledge of Ajax and JavaScript.

The client engine and update engine in ZK play the roles of pitcher and catcher, rendering Ajax communication transparent to developers. Events triggered by users are encapsulated and marshalled to event listeners running at the server.

User interface rendered on browsers are surrogated on the server as POJO components, alternation made on the POJO components are reflected to the client transparently.

With programs executed at the server, developers can leverage all the Java technologies, such as Java EE and Spring, while back-end data and services are readily available.

Server+client Fusion

ZK's Server+client Fusion gives developers the freedom to leverage the best of both sides.

The server-centric solution to Ajax brings a productivity boost, robustness, and security to Web application development; while client side solutions endows Web applications with greater controllability and the ability to leverage client side resources.

ZK marries the benefits of both to bring forth a developer-centric approach where developers continue to build large scale enterprise applications with all the robustness of Java technologies, but also are offered the flexibility to work directly with ZK's jQuery based widgets to further enhance user experience.

Declarative Programming

ZK User Interface Markup Language (ZUML) makes the design of rich user interfaces as simple as authoring HTML pages. ZUML is a variant of XUL inheriting all features available to XML, and separates the UI definition from the run-time logic.

ZUML also allows developers to automate CRUD between UI components and the data source with annotations, data binding and MVVM.

Fixing NullPointerException occurring inside org.zkoss.zk.ui.AbstractComponent#checkParentChild method

Hello,

This PR fixes NullPointerException ocurring inside org.zkoss.zk.ui.AbstractComponent#checkParentChild method.

It occurs in the following scenario:

Method org.zkoss.zk.ui.AbstractComponent#appendChild calls org.zkoss.zk.ui.AbstractComponent#insertBefore(child, null) method and returns its result. Inside org.zkoss.zk.ui.AbstractComponent#insertBefore method org.zkoss.zk.ui.AbstractComponent#checkParentChild(this, newChild) is called, where newChild parameter will be always null.

Inside org.zkoss.zk.ui.AbstractComponent#checkParentChild method we are not checking if the newChild is not null, but we should because of method org.zkoss.zk.ui.AbstractComponent#appendChild used in the ZK framework, which calls this method explicitly with null as a parameter.

I also wanted to write a unit test for that bug to avoid its regression, but you have custom project structure, so I don't know where I should put that potential test. You can point me to the correct place and then I can add a missing unit test.

Please review my PR. I'm looking forward to your reply.

Kind Regards, Piotr

ZK-4797: Supporting Jakarta EE namespace
I was the original requester of the ticket and am currently in the process of upgrading a bigger application towards jakarta.* namespace. During testing I patched ZK to my needs and thought it might be useful for you.

changed dependencies towards jakarta based counterparts

changed imports towards jakarta.*

include patched commons-fileupload (ouch...)

It's a very rough solution - but here goes nothing ;)

If there are any questions feel free to ping me.

Combobox item autodropdown on element load

After migrating from ZK version 8.5.0 to 8.6.0.1, we faced the issue with Combobox elements only in IE browser. By some reason, it can't be re-created in ZK fiddle, so let me just paste my small demo code here to be clear. Simple ZUL with combobox element:

<zk>
    <div apply="org.zkoss.bind.BindComposer" height="278px" width="443px"
         viewModel="@id('vm') @init('com.swissre.cre.presentation.mvc.TestModel')">
        <combobox id="cmbColor" width="150px"
                  model="@load(vm.names)" selectedItem="@bind(vm.iname)">
        </combobox>
    </div>
</zk>

My test model:

public class TestModel {

    private String iname;
    private List<String> names = Arrays.asList("Iüvanov", "alex", "ivan");

    @Init
    public void init() {
        setIname("Iüvanov");
    }

    public List<String> getNames() {
        return names;
    }

    public void setNames(List<String> names) {
        this.names = names;
    }

    public String getIname() {
        return iname;
    }

    public void setIname(String iname) {
        this.iname = iname;
    }

}

If the selected value contains characters like this "ü" (or any other diaeresis characters), the dropdown will be triggered on page re-load (on F5 for instance). If you remove this char from collection element it will not happen. I will be highly appreciated for any help with this issue. Thank you in advance.
