Error while trying to populate a table and refreshing

Question

Hello,
I have created a java class in which i have the POJO's(non BC) and generated data controls off the java class. The java class also contains a list (of user defined objects - lstPriceeventTypes) which i have dropped as a table on a jspx.
When i create a page: The list is initially empty. Now when i try to add a row using a command tool bar button which inturn invokes a method addSomething() in that same java class; in this method - i create the user defined object and add it to the list. Now i am expecting the table to show one row after i exit the addSomething method.
The problem: the table is not getting refreshed.
I tried
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("Execute"); // ID of the execute action binding you've created in your pagedef as above
System.out.println("bef ex");
Object result = operationBinding.execute();
with the pagdef having the entry
<action IterBinding="lstPriceeventTypesIterator" id="Execute"
RequiresUpdateModel="true" Action="iteratorExecute"/>
The method getBindings has
public BindingContainer getBindings() {
if (this.bindings == null) {
FacesContext fc = FacesContext.getCurrentInstance();
this.bindings = (
BindingContainer)fc.getApplication().evaluateExpressionGet(fc,
"#{bindings}",
BindingContainer.class);
return this.bindings;
So when i click on the button which accesses the method above; It throws the exception
WARNING: ADF: Adding the following JSF error message: Unexpected exception caught: java.lang.NoClassDefFoundError, msg=javax/faces/context/FacesContext
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.lang.NoClassDefFoundError, msg=javax/faces/context/FacesContext

I do have FacesContext in my library. Any pointers please?

It seemed to work:
Changed the following -
BindingContainer bindings = JUMetaObjectManager.getJUMom().getBindingContext().getCurrentBindingsEntry();
used a commandtoolbar button with partialSubmit="true" and the table having a partial trigger on the button (partialTriggers="::ctb1")
a normal commandButton wouldnt require a partialTrigger.....
Any idea if getting the bindingcontainer in this way is correct "JUMetaObjectManager.getJUMom().getBindingContext().getCurrentBindingsEntry();
