Syntax

@ExecutionArgParam("keyString")

Description

Target: A method's parameter (for initial and command methods)

Purpose: Tell binder to retrieve this parameter with specified key from the current execution's argument.

The annotation is applied to initial (or command) method's parameter. It declare the applied parameter should come from the current execution's argument with specified key.

Example

Assume we want to pass an argument to an included ZUL that uses a ViewModel: ExecutionParamVM.

outer ZUL

<window >
	<include arg1="foo" src="executionparam-inner.zul"/>
</window>

We use annotation to retrieve execution's argument with key "arg1".

public class ExecutionParamVM {


	private String arg1;
	
	@Init
	public void init(@ExecutionArgParam("arg1") String arg1){
		this.arg1 = arg1;
	}
	//setter, getter, and others
}

executionparam-inner.zul

	<vbox apply="org.zkoss.bind.BindComposer" viewModel="@id('vm') @init('foo.ExecutionParamVM')">
		
		<label value="@load(vm.arg1)"/>
	</vbox>

• The label will display "foo".
