@global-command(
[EL-expression], [arbitraryKey]=[EL-expression]
)
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 a comma to separate.
[arbitraryKey]=[EL-expression]
Basically, it uses key-value pairs. 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.
Since each annotation has different functions, some annotations may ignore key-value pair expressions 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.
<button label="Save" onClick="@command('saveOrder') @global-command('refresh')"/>
