          Description

          I have a row in a Table that represents an object instance (eg User). Once of the object attributes (role) is another object. If the User does not have a Role, I get an exception - 'IllegalArgumentException on HTMLStringBuffer - null value parameter' (line 93 in HTMLStringBuffer)

          I think the problem is around line 393 in Column.java. A test for a null value before doing a buffer.append() would fix this

          I'm subclassing Column right now to override the renderTableData method, which seems to work. The pertinent lines of code are:

          (replace line 393 with)
          if (columnValue != null)

          { buffer.append(columnValue); }

          Or should HTMLStringBuffer be more forgiving? Or both?
