preserveDataModel=true always throws ClassCastException
-------------------------------------------------------
Key: TOMAHAWK-241
URL: http://issues.apache.org/jira/browse/TOMAHAWK-241
Project: MyFaces Tomahawk
Type: Bug
Components: Extended Datatable
Versions: 1.1.1
Reporter: Robert Thaler
I have created a simple DataTable with scrolling ability using DataScroller. I
have set preserveDataModel to true.
The first call of the page works fine. If I would like to show the next page of
data rows I always receive the following exception:
java.lang.ClassCastException: javax.faces.model.ListDataModel
at
org.apache.myfaces.component.html.ext.HtmlDataTable.updateModelFromPreservedDataModel(HtmlDataTable.java:256)
at
org.apache.myfaces.component.html.ext.HtmlDataTable.processUpdates(HtmlDataTable.java:242)
at javax.faces.component.UIForm.processUpdates(UIForm.java:85)
I take a look in the source and it seems to me that the call of getDataModel()
is the problem. It never returns a _SerializabelDataModel. Souldn't it call
getPreservedDataModel()?
regards
Robert
