Hi Mathias!

Thanks for your answer.

Unfortunately I've still some problems with it ...

Changes I've made:

List contentList =3D new ArrayList();
for (int i =3D 0 ; i<10;i++) {
  contentList.add("row " + i);
}
DataModel content =3D new ListDataModel(contentList);
hdt.setValue(content);


The console-output looks like:

[STDOUT] >>>>>>>>>> =3D=3D> ROWCOUNT 2
[STDOUT] >>>>>>>>>> =3D=3D> ROWINDEX 0
[STDOUT] >>>>>>>>>> =3D=3D> WRAPPEDDATA =
[org.jbpm.taskmgmt.exe.TaskInstance@1a9b034, =
org.jbpm.taskmgmt.exe.TaskInstance@b950d1]
[STDOUT] >>>>>>>>>> =3D=3D> ROWDATA =
org.jbpm.taskmgmt.exe.TaskInstance@1a9b034
[STDOUT] >>>>>>>>>> =3D=3D> ROWCOUNT 2
[STDOUT] >>>>>>>>>> =3D=3D> ROWINDEX 0
[STDOUT] >>>>>>>>>> =3D=3D> WRAPPEDDATA =
[org.jbpm.taskmgmt.exe.TaskInstance@1a9b034, =
org.jbpm.taskmgmt.exe.TaskInstance@b950d1]
[STDOUT] >>>>>>>>>> =3D=3D> ROWDATA =
org.jbpm.taskmgmt.exe.TaskInstance@1a9b034

As you can see there are 2 elements (wrappeddata) but the rowindex is =
not incremented during the iteration ... so I always get the first =
element/object back by using 'content.getRowData()'.

What am I doing wrong?

Thanks,
Harry

use an instance of javax.faces.model.DataModel for the datatable=B4s
value. You can then use datamodel.getRowIndex() or
datamodel.getRowData() to get the current row value during the
iteration.
