As for me I prefer to
create such mapping to SelectOneMenu:
<h:selectOneMenu id="appCtrlSelect"
value="#{dsDescription.componentName}"
disabled="#{dsDescription.disAppCtrl}"
valueChangeListener="#{dsMap.appControlChange}"
style="width:200px;"> <f:selectItem
itemValue="Please select" />
<f:selectItems value="#{dsMap.appControls}" />
</h:selectOneMenu> Instead of:
<h:selectOneMenu id="appCtrlSelect" binding="#{dsDescription.DropDownCtrl}"
valueChangeListener="#{dsMap.appControlChange}"
style="width:200px;">
</h:selectOneMenu> I guess you will have
some problems during Session replication in the cluster if you have whole binding
to HtmlSelectOneMenu, because this bean which has mapping to HtmlSelectOneMenu
won’t correctly deserializable this property, if you will use transient
for this property you won’t desialize this at all. Best regards, Yura. From: Michael Heinen
[mailto:[EMAIL PROTECTED] Yura, Thanks for clarification. What do you exactly mean
with “add a few mappings to SelectOneMenu”? Do you see also any
issues when I mark the field transient and check in the getter whether the
instance is null and reinitialize it if necessary? I found a hint in the
WIKI regarding serialization and DataModels: http://wiki.apache.org/myfaces/FAQ I have a complex dynamic
model in the background and some dependencies between my BackingBeans so I think
requestScoped beans are currently not a real/performant alternative for me. Michael From:
[EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Hi, Well as JSF’s
UIComponent isn’t Seriaizable so all others ui components also
isn’t serializable. I recommended to use request beans instead of
session. If you are using session beans, for example you can try to add a few
mappings to SelectOneMenu, for example: Value selectItems Disable … etc. All these elements are
serializable even <f:selectItems> as SelectItem is Serializable. Using transient to
HtmlSelectOneMenu you will have some issues in future when you will try to
deserializable this object. Thanks, Yura. From: Hi, I came across the following exception in my log file: java.io.NotSerializableException:
javax.faces.component.html.HtmlSelectOneMenu The HtmlSelectOneMenu is a property in a session
scoped managed bean. Does this mean that I have to declare it transient in
order to play it safe? What about the implemented StateHolder interface? What about other component bindings? Thanks for clarification Michael |
