hi,
  So you are using the createInsert as a method call in task flow. That is your form/table will be come new rows and you want to disable some button.
Your task flow might be as below
      CreateInsert---->Page.
To do so
1.) Take properties of your method call and bind the Method property to a method in a bean (bean registered in the task flow with scope view or any higher scope)
2) Call the create insert operation programmatically in that method.
3) And in that method after the createinsert ,set a boolean variable in pageFlowScope.
4)Put this variable in the disable property or visible propery of the button you wabt to hide/diable.
eg:
    public void doCreateInserOperation(){
        try {
           // Programatically invoke CreateInsert
            DCBindingContainer bindings = (DCBindingContainer)getBindingContainer();
            bindings.getOperationBinding("CreateInsert").execute();
        //Set a variable in page Flow Scope 
        AdfFacesContext.getCurrentInstance().getPageFlowScope().put("disableButton", true)
        } catch (Exception e) {
            e.printStackTrace();
    public BindingContainer getBindingContainer() {
        FacesContext facesContext = getFacesContext();
        Application app = facesContext.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesContext.getELContext();
        ValueExpression valueExp = elFactory.createValueExpression(elContext, "#{bindings}", Object.class);
        return (BindingContainer)valueExp.getValue(elContext);
you can access this variable in EL expression as #{pageFlowScope.disableButton}. So when your page render it will be in CreateInsert mode and the button will be disabled/hidden.
I hope this will help you.
With regards,
Gijith.
