Brian Leathem commented on RF-12304:
------------------------------------
The javascript error is displayed in [line
310|https://github.com/richfaces/components/blob/develop/iteration/ui/src/main/resources/META-INF/resources/org.richfaces/extendedDataTable.js#L310],
because the [scrollElement
lookup|https://github.com/richfaces/components/blob/develop/iteration/ui/src/main/resources/META-INF/resources/org.richfaces/extendedDataTable.js#L172]
fails. The renderer does not create the scrollElement if there aren't any
[scrollable
columns|https://github.com/richfaces/components/blob/develop/iteration/ui/src/main/java/org/richfaces/renderkit/ExtendedDataTableRenderer.java#L363].
The workaround then, is to make sure the number assigned to the _frozenColumns_
attribute of the dataTable is < the total number of columns.
To correct this problem, we can either change the condition which creates the
scrollable element, or throw an exception when the number of frozen columns =
the total number of columns.

> If I place two or more extendedDataTables with selectionType="single" on one
> a page, it is only possible to make a selection on the first
> extendedDataTable. It is imposible to select a row on the second table. If I
> turn around the order of tables or delete the first one, it works fine for
> the other one. This means, the implementation itself shoul be correct,
> Do you have any ideas? Thanks for your help!!!
