I'm pretty sure there are some extra steps, but we've been using the following dependency and many UI events (including the data they carry) are being logged with it. That being said, they are being logged to Eclipse's console. I don't have access to the actual logs nor can be sure all the data in Eclipse's console is being saved there.

  <dependency>
        <groupId>org.zkoss.zk</groupId>
        <artifactId>zul</artifactId>
        <version>${zk.version}</version>
        <exclusions>
            <exclusion>
            <artifactId>slf4j-jdk14</artifactId>
            <groupId>org.slf4j</groupId>
            </exclusion>
        </exclusions>
  </dependency>

you can implement and configure (in your zk.xml) an ExecutionMonitor (which intercepts every UI event) https://www.zkoss.org/wiki/ZK%20Configuration%20Reference/zk.xml/The%20listener%20Element/The%20org.zkoss.zk.ui.util.ExecutionMonitor%20interface

<listener>
  <listener-class>my.package.MyExecutionMonitor</listener-class>
</listener>

From your description it sounds feasible to implement the eventStart and/or eventComplete methods of the ExecutionMonitor interface, where you can add your log statements in a single place.
