I tried to run the following example http://www.integratedmodelling.org/software/zk/zkworkflow/zkworkflow-demo.html with zk 5.0.2 and did not work.
I just want a simple example to get started, you can help me? please

<workflow-step step="sayHello" width="100%" height="330px">

<div>This component handles the "sayHello" state of the
<xhtml:a href="simple.xml"> simple.xml </xhtml:a> workflow.
You are seeing it because the workflow's initial action brought you there.
There are two other possible states, each with its workflow-step
components. The workflow-application only visualizes the GUI
components assigned to the current step, unless you override this
behavior with keepVisible = true.</div>

<div>In this state, you can choose to perform two actions, one that
computes the current time, and another that computes a simple
string.</div>

<div>The buttons below are generated by simply creating two button-trigger
components and passing the respective action names to them. Alternatively,
you can create triggers as complex as you like by wrapping ZUL components
in a worflow-trigger component and calling advanceWorkflow as a
response to user events.</div>

<!-- triggers for actions that are relevant to this step. If you don't

have the triggers, you can still advance the workflow programmatically.

-->

<hbox>

<button-trigger action="tellTime" label="Tell time" />

<button-trigger action="sayName" label="Say name" />

</hbox>

</vbox>

<workflow-step step="showTheTime" width="100%" height="330px">

<div>

This component handles the "showTheTime" step. The action that leads
into this step is defined to calculate the current date and set it in
the action variable "time" every time it is executed. The label below
is set to react to a state transition by looking for the value of the
"time" variable in the action that caused it, and setting it as the
label text. You should see the time when you clicked the action button
that sent you here.

</div>

<label>

<!-- the "data" field has been set in the action by the

workflow. Note that other transitions will also invoke

this one with a null value, so you want to make sure

that it's fine to have null as a result of

getActionData.

-->

self.setValue(event.data.getVariable("time"));

</attribute>

</label>

<button-trigger action="goBack" label="Go back" />

</vbox>

</workflow-step>

<workflow-step step="showMyName" width="100%" height="330px">

<div>

This component handles the "showMyName" step. The action that leads
into this step defines the "name" variable. The label below
simply shows it. Variables can be set by actions, steps, or
globally in workflows. The variable resolver looks for a name
in the action, then in the current steps, then in the workflow.

</div>

<div>

Defining variables in steps with the same name is a simple way to
track changing state in workflows. The variables are evaluated
by MVEL code in the same JVM that runs your application and can
be of any Java type. You can also define variables explicitly
in event handlers.

</div>

<label>

<!-- name is another workflow-computed variable defined for the

action that brings us here. -->

self.setValue(event.data.getVariable("name"));

</attribute>

</label>

<button-trigger action="goBack" label="Go back" />

</vbox>

</workflow-step>

</groupbox>

<!-- will display status message when an action that has it starts, and

resets it when it ends. Useful for long-running actions, e.g. those that

call another workflow or perform complex calculations.

-->

<label width="100%" value="Status here" id="status"

onStatusMessage="status.setValue(event.data)"/>

</vbox>

</workflow-application>

I don't think you can merge it like this, in Zul, every XML-Tag must has destination Device to handle it, and ZK already implemented zul, zk, xhtml and etc. the others should be treated as native namespace and directly out put as text.
could you examine what you want to do and maybe we can give you better surggestion.

I just try to reproduce the example http://www.integratedmodelling.org/software/zk/zkworkflow/zkworkflow-demo.html.
I'm on the right track to work on zk workflow?
