  h2. Overview
 _Since 4.2 EE_
  
 The _ace:listExporter_ component is a utility to export data from an ace:list component as an Excel, PDF, XML or CSV document. This component renders an HTML button. More components and HTML elements can be nested inside this tag to give a different look to the button..
  
 {tip}See the ICEfaces Showcase [Live Demo|http://icefaces-showcase.icesoft.org/showcase.jsf?grp=ace:listExporter] of this component, complete with source code.{tip}
  
  
 h2. Getting Started
  
 In most cases, it's enough to add the tag on the page without any configuration.
  
 {panel}
 {code:xml|borderStyle=dashed}<html ... xmlns:ace="http://www.icefaces.org/icefaces/components">
 <h:body>
  <h:form>
  <ace:list id="myList/>
  <ace:listExporter
  label="Export File"
  type="csv"
  target="myList"
  fileName="data"/>
  </h:form>
 </h:body>
 </html>
 {code}
 {panel}
  
 h2. Attributes
  
 {tip:title=TagLib Documentation}This section covers attributes involved in the typical use-cases for this component. For reference, the complete taglib documentation for this component is available [here|http://res.icesoft.org/docs/v4_latest/ace/tld/ace/listExporter.html].{tip}

 h2. Client Behavior Events
  
 None.
  
 h2. Javascript API
  
 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.

 None at the moment.
