How to attach actionListener for events in Richfaces 4

[langer123]

I have the follwoing code from Richfaces 3.3

<h:inputText id="transamount" value="#{myBean.amount}">
    <a4j:support event="onkeyup" ajaxSingle="true" actionListener="#{myBean.validTransAmt}" requestDelay="200" ignoreDupResponses="true" reRender="main,submitButton" />
</h:inputText>

I need to upgrade it to Richfaces 4 and am unsure how to attach the actionListener now as it's not supported under the a4j:ajax component which replaces a4j:support.

This is what I have so far.

<h:inputText id="transamount" value="#{myBean.amount}">
    <a4j:ajax event="onkeyup" reRender="main,submitButton" />
</h:inputText>

Could someone explain how to attach an actionListener here?

Thanks

Hi Thomas,

you can use attribute listener of a4j:ajax:

<h:inputText id="transamount" value="#{myBean.amount}">
    <a4j:ajax event="keyup" render="main,submitButton" listener="#{myBean.validTransAmt}"/>
</h:inputText>

Be aware of the fact that event attribute consumes the name of event itself, i.e. without "on" and attribute reRender was renamed so that it is the same as in f:ajax.

Your listener then will look like this:

public void validTransAmt(javax.faces.event.AjaxBehaviorEvent event) {
       // implementation
}

Regards,

Palo

Thanks Pavol

Just one other quick question.

What about the use of ajaxSingle and requestDelay? They dont seem to be avbailable for a4j:ajax either?

Attribute ajaxSingle was removed from RichFaces 4. You can use execute="@this" instead. You have to use a4j:attachQueue behavior instead of attribute requestDelay, please see component reference [1].

IMHO you should have a look on our Migration guide [2] which explains all changes.
