[OmniFaces utilities (2.4)] Get the source of the currently invoked action

---

[OmniFaces utilities] The getCurrentActionSource() method returns the source of the currently invoked action, or null if there is none, which may happen when the current request is not a postback request at all, or when the view has been changed by for example a successful navigation. If the latter is the case, you'd better invoke this method before navigation.

Method:

Usage:

import org.omnifaces.util.Components;

...

UIComponent action = Components.getCurrentActionSource();

You can see several examples of using this method as:

- check whether the given component has invoked the form submit (hasInvokedSubmit()):

public static boolean hasInvokedSubmit(UIComponent component) {

 UIComponent source = getCurrentActionSource();

 return source != null && source.equals(component);

}

- get the currently invoked UI command component (getCurrentCommand()):

public static UICommand getCurrentCommand() {

 UIComponent source = getCurrentActionSource();

 return source instanceof UICommand ? (UICommand) source : null;

}
