The creation of the object (managed bean) happens automatically, you must not do that by yourself (because you will receive/create another instance!). The point is now to get the correct object (created by faces context usually by the first access!).

The code in the script step looks like follows:

import javax.faces.context.FacesContextFactory;
import javax.faces.context.FacesContext;
import ch.soreco.mbean.mb.SimpleBean;

SimpleBean sb;
FacesContext context = FacesContext.getCurrentInstance();

sb = context.getApplication().evaluateExpressionGet(context, "#{simpleBean}", SimpleBean.class) as SimpleBean;

// invoke method of the managed bean
sb.setS1(in.input);

The code of the managed bean:

package ch.soreco.mbean.mb;

import javax.faces.bean.SessionScoped;
import javax.faces.bean.ManagedBean;

import ch.ivyteam.ivy.environment.Ivy;


@ManagedBean(name = "simpleBean")
@SessionScoped
public class SimpleBean 
{
    private String s1;
    private int counterSet = -1;
    private int counterGet = -1;


    public SimpleBean() 
    {
        super();
        s1 = "--";
        counterSet = 0;
        counterGet = 0;
        Ivy.log().warn("BEAN created!");
    }

    public String getS1() {
        counterGet++;
        Ivy.log().warn("BEAN getter called: "+counterGet);
        return s1;
    }

    public void setS1(String s1) {
        counterSet++;
        Ivy.log().warn("BEAN setter called: "+counterSet);
        this.s1 = s1;
    }

    public int getCounterSet() {
        return counterSet;
    }

    public void setCounterSet(int counterSet) {
        this.counterSet = counterSet;
    }

    public int getCounterGet() {
        return counterGet;
    }

    public void setCounterGet(int counterGet) {
        this.counterGet = counterGet;
    }
}

This approach works surely with session or application scoped beans.

Usually i do that way: First i will create instance:

FacesContext context = FacesContext.getCurrentInstance();       
            FileManagerBean fileManagerBean=new FileManagerBean();
            context.getExternalContext().getSessionMap().put("fileManagerBean", fileManagerBean);

then i get it when i want to use like this:

import javax.faces.context.FacesContext;
import ch.ivyteam.ivy.addons.filemanager.html.managedbean.FileManagerBean;
FacesContext context = FacesContext.getCurrentInstance();               
FileManagerBean fileManagerBean=context.getExternalContext().getSessionMap().get("fileManagerBean") as FileManagerBean;
in.enablePreviewLink = fileManagerBean.enablePreviewLink;

In your Script-Step:

import de.path.to.MyBean;
MyBean instanceOfMyBean = new MyBean(); 
instanceOfMyBean.setWhatever(10);

If you want to use this bean in your view just declare a data-object of the given type (de.azt.exampleData.MapBean) in your data-class and bind this as model in your view code, f.e.:

<p:gmap zoom="6" type="TERRAIN" center="#{data.geoLat}, #{data.geoLng}" id="gmap" model="#{data.mapModel}">

The corresponding code in your script step would then be:

import de.azt.exampleData.MapBean;
out.mapModel = new MapBean(out.projects, true, out.auditors, false, true);

Whereas you need to pass the attributes from your database-query as parameters to the constructor of your bean.

Hope that helps.
