Problem with lifecycle

Question

Hi,
I'm having some problems understanding the JSF lifecycle.
I create a very simple page, with just one textfield:
<h:inputText binding="#{test.testField1}" id="testField1" onchange="this.form.submit();"
value="#{test.sampleText}" valueChangeListener="#{test.testField1_processValueChange}"/>
I have a ValueChangeListener, and an onchange action. The TextField is bound to the sampleText property of my Bean.
THe question is: when is that value updated? It seems that it is never the case.
In the constructor of the bean, I set the default value of sampleText to:
sampleText = "hello world";
Then, in the ValueChangeListener, I do the following:
System.out.println("Old value: " + vce.getOldValue());
System.out.println("New value: " + vce.getNewValue());
System.out.println("Value : " + sampleText);
The problem is that whatever I type in the textfield, OldValue is always 'hello world', NewValue is the new value I typed, and sampleText is always 'hello world'
What I expected to have was:
Old Value: hello world
New Value: newValue1
Old Value: newValue1
New Value: newValue2
and so on...
What's wrong with my stuff? Why is the sampleText never updated? How should I proceed to perform a one-time initialization, and get the property updated everytime I make a change?
Thanks

Answer 1

What I would like is an input field and a datatable
Inputfield is a date and datatable contains all rows from a database that match the given date.
So what I would like is when I change the input field, automatically, the datatable is updated.
Since datatable comes from a rowset, I need to do setObject() with the new value, and execute the rowset again.
That's what I would like, but it does not work. How can I get the new value to update my datatable?
Cheers,
