 h2. Overview
 _Since 2.0_
  
 The _ace:pushButton_ component allows submission of a form in it's entirety or also the submission of itself only. This component supports an action attribute as well as an _actionListener_ attribute similar to a _h:commandButton_.

 h2. Event Listeners
  
 As a descendant of UICommand, this component supports an action listener.
  
 | actionListener | Method that will be notified when the component is activated by the user |
  
 h2. Client Behavior Events
  
 | action | Fired when the button is clicked or pressed by any other means (default event). |
  
 {tip}Prior to 4.0 this event was named "activate". The "activate" event name is now deprecated but treated as an alias for "action" for backwards compatibility with existing applications.{tip}
  
 h2. JavaScript API
  
 h4. ICEfaces 3.x
  
 The client side component object is exposed through the global variable name specified in the *widgetVar* attribute.
  
 h4. ICEfaces 4+
  
 The "widgetVar" attribute on the ACE components has been removed in ICEfaces 4 and in its place a new "ice.ace.instance()" client JavaScript object lookup API has been introduced. The reason for this change is to enable lazy-initialization of the ACE component JavaScript objects to improve runtime performance and reduce browser memory use.
  
 {code}var widget = ice.ace.instance('frm:componentId);{code}
  
 {tip}The _ice.ace.instance_ function requires the _full_ client id of the component to be specified, such as "j_idt77:componentId" instead of just "componentId". To reduce the complexity of working with complete IDs with this function it may be preferable in some cases to use {{prependId="false"}} in the enclosing form (e.g. _<h:form prependId="false">_).{tip}
  
 {info}This component doesn't have a client-side API made specifically to be used by application developers. However, the component's internal methods and variables can be accessed in this way, including the underlying jQuery object and objects from underlying Javascript libraries (if applicable), and can be used for whatever purpose a developer might have in mind.
 {info}
