Edit Procedure with selected values

Question

Hi,
I have an edit form where i drugged my view as an adf form.
I created in my Application Module a method called "save()" which what i do is just commit:
try {
getDBTransaction().commit();
} catch (JboException ex) {
getDBTransaction().rollback();
throw ex;
On my form i have some radio buttons. One of them is called LandType, with two options (OptionA and OptionB).
Please note that this is an edit operation so there is a preselected value when i edit a record.
I created some entity level validation which is conditional based on the selection of the above radio button. For example i have 2 input boxes, "InputA" and "InputB". If the user selects "OptionA" the "InputA" is required. If the user selectd "OptionB" then "InputB" is required.
For the create operation everything runs smoothly.
For the edit operation i face this problem.
I have a record with "OptionA" selected and "InputA" with some value ("InputB" is empty)
When i change to "OptionB", i render the "InputB" text box and i get my error message for an empty field("InputB"). If i press again save (calls my commit method in my AppModule) then the radio button from "OptionB" goes back to "OptionA" and if i click again save, it saves the changes!!!
How can i overcome this? I want the new value selected to remain.
Thanks
Antonis

Some glitch in my blogging software currently prevents me from posting it on my blog, but I've uploaded a 10.1.3.3-based example workspace here:
http://otn.oracle.com/products/jdev/tips/muench/condreq/OptionalRequiredFields.zip
This is the example blurb that will eventually appear as example #124 on my blog when I am again able to upload to it.
This example illustrates how to validate and render
conditionally-required attributes. After running the included
CreateTables.sql script to create the
OPTIONAL_REQUIRED_TEST table, run the TestPage.jspx to
see that when a row has its RowType attribute set to the value
A then the ValueA inputText component renders, while if
its RowType attribute is instead set to the value B then
the ValueB inputText field renders. These fields set the
showRequired property to true to show the required field
indicator to the end-user even though the underlying ValueA and
ValueB attribute are not marked as mandatory. The conditional
mandatory validation is performed in the TestEntity entity
object using entity-level method validators. The radio group UI
component is marked to have its autoSubmit property true, and
the ValueChangeListener method in the backing bean for the page
sets a request-scope attribute as a flag to indicate that the row type
is changing. This flag is then referenced by the
ConditionalValidationPageController -- identical in function to
the one you might have seen in Example# 62 "Cascading Lists in JSF" --
which is configured to be used by the TestPage by setting the
ControllerClass property of its page definition. This
customized page controller avoids validating the row if it detects
that the row type is changing. The conditional rendering of the ValueA
or ValueB inputText components is handled declaratively using an
appropriate EL expression for the component's rendered
property. When the autoSubmit radio group (with component id
"RowTypeRadio") causes its partial-page request, the panelForm
component in which the ValueA and ValueB inputText's reside is
declaratively "repainted" by having its partialTriggers
attribute set to that "RowTypeRadio" id value. By performing the
partial-page triggering on the enclosing panelForm component, you
avoid the gotchas related to having PPR events delivered to
currently-unrendered components.
