@global-command

Syntax

@global-command( [EL-expression], [arbitraryKey]=[EL-expression] )

Description

Target Attribute: event attributes (e.g. onClick, onOK)

Purpose: Specify which global command to execute when the event fires

If you use this binding with a local command binding, remember that local command is always executed first.

You can pass arbitrary arguments in key-value pairs with comma separated.

[arbitraryKey]=[EL-expression]

It's key-value pairs basically. You can write multiple key-value pairs with different key names.

An EL expression without key is set to a default key named "value" implicitly.

Due to each annotation has different functions, some annotations may ignore key-value pair expression other than default key, e.g.@id.

[arbitraryKey]

It could be any name, it's used as a key for parameter related Java annotation in a ViewModel.

Example

<button label="Save" onClick="@command('saveOrder') @global-command('refresh')" />

<button label="ShowAll" onClick="@global-command('show')" />

<button label="Index" onClick="@command('showIndex') @global-command('showIndex', index=10, keyword='myKeyword')"/>
