Subject [jira] Commented: (MYFACES-749) inputText refresh problem
Date Tue, 25 Oct 2005 18:43:55 GMT
    [ http://issues.apache.org/jira/browse/MYFACES-749?page=comments#action_12355887 ] 

Mike Kienenberger commented on MYFACES-749:
-------------------------------------------

As I stated in the message posted to the list, the behavior you are trying to perform is very
hard in JSF.   The behavior you're seeing is unlikely to be a bug, though.   Using "immediate"
is mutually-exclusive with working with updated-models.   immediate is only useful for trivial
things like implementing cancel buttons.   I also need to update selection lists on my page
when other selection lists change without triggering validation problems.  That's why I'm
writing the OptionalValidationFramework. to get around these problems. 

http://wiki.apache.org/myfaces/OptionalValidationFramework.

The only way you'll be able to demonstrate that this is a bug is to remove everything but
selectOneMenu, inputText, and outputText from the page and show that it fails to work without
any "immediate=true" attributes on the page.  If you can get it to this point and still show
the problem, post a simplified example of your problem to this issue, and someone will take
a look   (faces-config, jsp page, backing bean code).

Otherwise, you can ask for help on determining a workaround to your situation by asking on
the myfaces-user mailing list.   I probably won't respond here again unless you've demonstrated
it's a bug.

> I have a drop down LEVELS with an valueChangeListener and an inputText field that is
supposed to change when the drop down is changed. The inputText field is bound to a simple
String object.
> When the value of the drop down changes, request submits and upon processing the value
of the backing bean changes. when comes to UI, its not showing the changed value in the <h:inputText>
field, but its showing the updated value in <h:outputText> field.
