Tables with non-string empty cells make the column disappear

[gphilipp]

Expected :
| credits | name | birthDate |
| 1,000 | Sid Vicious | |
| 3,000 | Frank Zappa | 21/12/1940 |

Actual :
| credits | name |
| 1,000 | Sid Vicious |
| 3,000 | Frank Zappa |

I'm investigating the issue. Seems to occur only with non-string fields.

[gphilipp]

It doesn't happen with String fields because empty cells are parsed as empty string instead of null.
Unfortunately, it seems XStream doesn't handle null values in AbstractReflectionConverter. See line 120 :

if (info.value != null) {

Not sure what option do we have there. @aslakhellesoy any thoughts ?

The problem is that cucumber.table.xstream.ListOfObjectWriter assumes that XStream will write out null fields, which it won't.

This means that tableConverter.toTable(listOfPojo) won't work if one of the pojos have null fields. Null fields can result from parsing a gherkin table, but it can also result from constructing pojos manually.

I'm working on a fix in ListOfObjectWriter

Excellent, thanks !
