Figure 5.1. <a4j:commandButton>

Note

Button controls are typically used to perform complete form submissions for data storing. As a consequence, the <a4j:commandButton> component has the execute="@form" setting by default. To limit rendering to a different scope, redefine the execute attribute.

⁠5.4.1. Basic usage

The <a4j:commandButton> requires only the value attribute to function. Use the value attribute to specify the text of the button.
By default, the <a4j:commandButton> uses the click event instead of the submit event.
