To get a page fragment's button id in another page's backing bean

Question

Hi,
I've a page fragment file with command button 1 and a jspx page with command button 2. On clicking button 1, jspx page opened in a dialog window. When i press button 2, button 1 also get pressed automatically. In action method of button 2, the id of button 1 returns null. How can i get the id of button 1 in button 2's action method. Page fragment and jspx page have separate backing bean. And both the buttons are bound with those bean respectively.
The code in jspz page's backing bean is,
fragmentBean frag = new fragmentBean();
frag.getButton1();
This 'frag.getButton1();' returns null value. how can i get button 1's id?

Hi,
fragmentBean frag = new fragmentBean();
frag.getButton1();
you create a new bean instance instead of having JSF serving you this. What you should do is
ELContext context = FacesContext-->ELContext
ExpressionFactory factory = FacesContext --> Application --> ExpressionFactory
ValueExpression ve = factory.createValueExpession(..., "#{managedBeanToReference}", ...);
fragmentBean bean = (fragmentBean) ve.getValue(...);
