Leonardo Uribe reopened MYFACES-1860:
-------------------------------------
This should be closed as invalid, since no changes on code was applied, so I
have to reopen and close it
> valueChangeListener problematic behavior
> ----------------------------------------
>
> Key: MYFACES-1860
> URL: https://issues.apache.org/jira/browse/MYFACES-1860
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 1.2.2
> Reporter: Guy Bashan
> Assignee: Leonardo Uribe
>
> I know this is probably a known issue, and it is a matter of specification,
> but still, I think it is an annoying issue that makes jsf impossible in the
> simplest cases:
> Suppose there is a simple dropdown with 2 values: 1, 2. The selected value is
> set to: 1 (in the bean constructor or in faces-config).
> Something like this:
> <h:selectOneMenu value="#{cmp_browse.selectedPage}"
> onchange="submit();"
>
> valueChangeListener="#{cmp_browse.gotoPageAction}">
> <f:selectItems value="#{cmp_browse.pages}" />
> </h:selectOneMenu>
> Now, when changing the value from 1 to 2, the event will be fired. But, when
> changing the value from 2 to 1, no event is fired.
> It is clear why event was not fired: initial value is 1, newly changed value
> is also 1. No event fired.
> But, logically it is wrong, since I did changed the dropdown value from 2 to
> 1.
> In plain old JSP programming, this was so easy to accomplish task (reacting
> to some change in dropdown and doing some action), that becomes very annoying
> in JSF.
> I know one would say: what is the problem? change the scope of the bean to
> session. I don't accept this solution and generally I almost never work with
> session scoped beans. I don't see any reason starting to fill the user
> session with tons of data in order to solve simple problems (in general, I
> don't like to put information that is not really required in the session).
