If I switch from scrollableDataGrid to dataGrid, it works fine. It could be that scrollableDataGrid requires its own special DataModel implementation?

[pmuir]

Ask in richfaces forum.

[igx89]

I looked around in the code, and scrollableDataGrid definitely uses its own DataModel class (org.richfaces.model.ScrollableTableDataModel, extending org.ajax4jsf.model.ExtendedDataModel which itself extends javax.faces.model.DataModel -- the base class for Seam's DataModel stuff).

So the question is: does Seam want to ease the use of scrollableDataGrid like it does with dataGrid? If so, then some modifications to Seam will need to be done to allow that.

[dhinojosa]

Is 'staff' mapped to something else other than the entity of Staff? It says in the stack trace that it staff is a @DataModel. So do you have:

@Data List<Staff> staff;

anywhere in your code?

[igx89]

availableStaff is the data model, staff is the iterator variable in the scrollableDataGrid.

Seam does nothing special for dataGrid. Have you checked you don't have stale jars lying around?

[igx89]

Seam has @DataModel and supporting classes (like org.jboss.seam.jsf.ListDataModel and org.jboss.seam.faces.DataModels) which ease the use of dataGrid. The problem is that scrollableDataGrid requires some additional methods on the data model (added by classes I mentioned in a previous reply), and so Seam's @DataModel annotation can't be used with scrollableDataGrid.

Does that make sense?

[maksimkaszynski]

Which version of RichFaces are you using. 3.1x version that comes with Seam 2.0 doesn't support javax.faces.model.DataModel as its value.

Richfaces version from the trunk does. So you can easily use trunk version of richfaces.

[igx89]

Great! I'll give that a try when 3.2 comes out. Does sorting work, or would that require modifications to Seam?

[esmith1]

I have run into this issue too. It appears to have been reported here, http://jira.jboss.com/jira/browse/RF-1711, and curiously has a status of unresolved.

I say curiously because --as a previous post wrote that it was fixed in trunk-- if I grab the latest 3.2.0 snapshot richfaces jars from here, http://snapshots.jboss.org/maven2/org/richfaces/ui/richfaces-ui/3.2.0-SNAPSHOT/ then the problem goes away -- although I now hit a new stack trace at org.richfaces.renderkit.html.ScrollableDataTableBaseRenderer.getColumnSorting(ScrollableDataTableBaseRenderer.java:934) which I will post in a new thread after I pin it down a bit more. I'd be interested if anyone else has similar experience.

[annechou]

Have you uncovered any further information about this error? I am seeing the same stack trace when using a ScrollableDataTable with Ajax. (A regular DataTable works fine.)
