[ http://issues.apache.org/jira/browse/MYFACES-1492?page=comments#action_12449384 ] Mario Ivankovits commented on MYFACES-1492: -------------------------------------------
I too find its "strange" that they fire the event before the update_model phase ... I'll say thats the "technical point of view", hmmm, and maybe you can use it to veto this particular change ... is this possible? Anyway, thats why we developed the valueChangeNotifier ..... so everything is wonderful again :-D > valueChangeListener is being called before the setters, even with > immediate="true" > ---------------------------------------------------------------------------------- > > Key: MYFACES-1492 > URL: http://issues.apache.org/jira/browse/MYFACES-1492 > Project: MyFaces Core > Issue Type: Bug > Components: General > Affects Versions: 1.1.4 > Reporter: Mircea Zahan > Assigned To: Cagatay Civici > Priority: Critical > Fix For: 1.1.4 > > > valueChangeListener is being called before the setters, even with > immediate="true". > This is not the right behavior since it overwrites any property modified in > the event handler. > <t:panelGrid columns="2" cellpadding="0" cellspacing="5px" > columnClasses="left top, left top"> > <t:outputLabel for="infoId" value="Options"/> > <t:selectOneMenu id="infoId" value="#{productBean.infoId}" > onchange="submit()" valueChangeListener="#{productBean.valueChangedHandler}" > immediate="true"> > <f:selectItem itemValue="-1" itemLabel="<new short info>"/> > <f:selectItems value="#{productBean.shortInfoSelectItems}"/> > </t:selectOneMenu> > <t:outputLabel for="descText" value="Description"/> > <t:inputTextarea id="descText" rows="8" > value="#{productBean.description}"/> > <t:outputLabel for="utilText" value="Usage"/> > <t:inputTextarea id="utilText" styleClass="wXXXL" rows="8" > value="#{productBean.usage}"/> > </t:panelGrid> > public class ProductBean { > private Long infoId; > private String description; > private String usage; > // .... setters and getters for the above properties > public void valueChangedHandler(ValueChangeEvent event) { > Long infoId = (Long) event.getNewValue(); > if ((infoId != null) && (infoId > 0)) { > //DataService and ProductInfo are related to Hibernate > ProductInfo info = DataService.getProductInfo(infoId); > this.description = info.getDescription(); > this.usage = info.getUsage(); > } > } > } > Description and Usage properties can never be changed since they get > overwritten with the initial values. > :((((((((((((((((((((((((( -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
