<rich:listShuttle - ERROR - has invalid value expression

[khaled_288]

Dears,

I'm using <rich:listShuttle and facing following validation error I dont know why?
this error happen when there is any validation error in the page then i try to submit the form again.

ERROR:

Component mainForm:clientTypesOptionsInput has invalid value expression com.elm.carportal.web.vobjects.LookupValue@5

While clientTypesOptionsInput is the component id and LookupValue is the item object.

I make sure that i have a lookupValueConverter and override the object's equals and hashCode methods.

I want to know when this error happen? when rich:list says that value is invalid?

[khaled_288]

I make the value object LookupValue implements Serializable

It works fine ..


I dont know why must be Serializable?
and where is the Serialization happen?
