PropertyColumn

[Björn-Peter Tietjens <bj...@web.de>]

Hi,

when trying to user a PropertyColumn like this:
...
List<IColumn> columns = new ArrayList<IColumn>();
columns.add(new PropertyColumn<Long>(new Model<String>("ID"), "id"));
columns.add(new PropertyColumn<String>(new Model<String>("First 
Name"),"firstName","firstName"));
...

I keep getting the following error:
..."The type PropertyColumn is not generic; it cannot be parameterized 
with arguments <Long>"...

Why is that? What am I doing wrong?

Cheers
Björn
