Problem with a4j:jsFunction data in Richfaces 4

[schoenb]

Hi,

I have defined a function like this im my JSF2 Project

<a4j:jsFunction ajaxSingle="true" data="#{sBOsmShow.longitude}" name="centerAndZoom" oncomplete="alert(data)">

</a4j:jsFunction>

I trigger this function from a a4j:commandButton

<a4j:commandButton value="Anzeigen" onclick="centerAndZoom();" execute="zoomDataGrid"/>

After clicking the button no alert-box is displayed. The getLogitude is called in the session bean. If I change alert(data) to alert('test') the "test" is displayed. It seems there is a problem using data from the sessionbean as parameter fpr the javascript function.

Richfaces 4.3.2

JBoss 7.1.1

Can some help me?

Greetings

Arndt

Is use Richfaces 4.2.3 - a typo

Here's an example that I have used in the past, there are a few minor changes from your code above, notably the use

of a4j:param and event.data. Hopefully you can adapt this to meet your requirements.

<a4j:commandButton onclick="jsTest();" ...

<a4j:jsFunction name="jsTest"

                    oncomplete="alert(event.data)"

                    action="#{bean.jsTestAction}"

                    data="#{bean.jsTestData}">

        <a4j:param name="p1" value="Fred" assignTo="#{bean.jsTestParam}"/>

</a4j:jsFunction>

public String jsTestAction() {

        jsTestData = "Hello " + jsTestParam;

        return null;

}

Your mistake in receive data via "data" variable, you must take data via "event.data"

This is examle from book:

<h:form>

     <input type="button" value="Update" onclick="updateName('Joe');"/>

     <a4j:jsFunction name="updateName" render="showname" data="#{jsFunctionNameBean.greeting}" oncomplete="alert(event.data)">

          <a4j:param name="param1" assignTo="#{jsFunctionNameBean.name}"/>

     </a4j:jsFunction>

     <h:outputText id="showname" value="#{jsFunctionNameBean.greeting}"/>

</h:form>

@ManagedBean (name="jsFunctionNameBean")

@RequestScoped

public class JSFunctionNameBean {

     private String name; // setter and getter

     public String getGreeting () {

          return "Hello "+this.name;

     }

}

Adam.
