Hi Sandalo,

you may refer to
ZK MVC
Implementing_ZK_MVC

or do you mean "apply a composer to each page"?
it can be done with System-level Composer

Hi Sandalo,
let's say, there are two composer called TestComposer and TestComposerTwo,
and we want apply TestComposer to all windows not applied the TestComposerTwo,

there are several things to do:

1.
make sure Window is the root component of a page,
system-level composer will only apply to root components.

for example, if there are buttonOne and buttonTwo in composer and the zul is as follows:

<zk>
	<window>
		<window>
			<button id="buttonTwo" label="buttonTwo zero in test" />
		</window>
	</window>
	<window>
		<button id="buttonOne" label="buttonOne in test" />
	</window>
</zk>

then the buttonOne will be wired but buttonTwo will not.

2.
In TestComposer, check whether the window is applied other composer,
if it is true then just return, as follows:

public void doAfterCompose(Component comp) throws Exception {
	Iterator it = ((Window)comp).getAttributes().keySet().iterator();
	while (it.hasNext()) {
		// add more check if more other composers
		if ("$TestComposerTwo".equals(it.next().toString()))
			return;
	}
	super.doAfterCompose(comp);
}

3.
regist TestComposer as system-level composer in /WEB-INF/zk.xml

<listener>
	<listener-class>test.TestComposer</listener-class>
</listener>

it should work now.
