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). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
