Leonardo Uribe reopened TOMAHAWK-1460:
--------------------------------------
I finally was able to reproduce it using the following structure:
<t:dataList value="#{test.someList}" var="row" preserveDataModel="true">
<t:dataTable value="#{bean.map[row.id]}" var="item"
preserveDataModel="true">
.......
The exception is this:
javax.faces.FacesException: java.lang.ClassCastException:
javax.faces.model.ListDataModel cannot be cast to
org.apache.myfaces.component.html.ext._SerializableDataModel

> Components: Extended Datatable
> Affects Versions: 1.1.9
> Environment: Mac OS 10.5.8

> The interesting point here is that _preserveDataModel is set to null.
> Later, during processUpdates(), updateModelFromPreservedDataModel() will
> call getDataModel (as listed above), however, since _preservedDataModel was
> set
> to null, the call is delegated to the super class, UIData, which returns
> ListDataModel.
> This change in the code path is new spec required functionality where
> UIViewRoot.processRestoreState()
> uses the TreeVisitor to notify components of the PostRestoreStateEvent.
> Given this, I'm sure the
> problem will be manifest with MyFaces 2.0.0.
> WORKAROUND: set preservDataModel to false.
