valueChangeListener - inputText - Which method is correct?

Tue, 25 Oct 2005 03:04:04 -0700

I’ve seen 3 different examples of using the “valueChangeListener” attribute.

 

I’ve seen…

 

Example 1:

 

JSP

<h:inputText value="foo">
 <f:valueChangeListener type="com.jsf.MyValueChangeListener"/>
</h:inputText>


 



CODE



public class MyValueChangeListener implements ValueChangeListener {
  public MyValueChangeListener() {  }
 
  public void processValueChange(ValueChangeEvent vce) throws AbortProcessingException  {
     System.out.println("A value has changed!");
  }
}



 



Example 2:



 



JSP



<h:inputText id="partNumber" value="#{nonConformingMaterial.partNumber}" required="true" 



valueChangeListener="#{nonConformingMaterial.changeEvent}"



      onclick="submit()"



      immediate="true"



/>  




 



Example 3:



 



JSP



<s:inputSuggestAjax suggestedItemsMethod="#{inputSuggestAjax.getItems}" styleLocation="" />



 



 



 



I like example 3, very sexy. (see http://irian.at/myfaces-sandbox/inputSuggestAjax.jsf)



But it’s not what I need in my application. 



 



What I need is, when an inputText is filled in, an action is
called so that another inputText field is automatically filled in.



 



I presume that I should be trying to get example 1 working. Would
you agree?
