Programmatically binding of an UIComponent to a backing bean

[toroskar]

I am developing a application in which I am trying to bind an UIComponent (in this case the rich:modalPanel) component to a backing bean. When i do this fro an jsf file it works fine

<rich:panel binding="#{logit.visualizationManager.visualize(visualizationGraph)}"/>

But in my case I have to do the same programmatically, but I'm not able to get it working.

This is the code:

HtmlModalPanel modalPanel = new HtmlModalPanel();

ValueExpression ve = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().createValueExpression( FacesContext.getCurrentInstance().getELContext(),"#
{logit$visualizationManager.childrenViz}",String.class);

modalPanel.setValueExpression("binding" +",ve);

I didn't get any type of errors, but nothing is happening..

Can anyone help me to figure out what's wrong? Thanks in advance
