Export of child items

[base]

Export of items does not allow selection of child items. I think that it would be an improvement to also be able to export these child items. If multiple child items are referenced, these could be separated with a comma. In this way one would be able to export the same table that is shown on the screen.

[Nicklas Nordborg]

The table exporter plug-in only supports exporting "simple" properties. This is a limitation in the implementation caused by the "generic" nature of the exporter. The details:

1. The exporter is given a query and a list of columns.
2. The exporter executes the query and uses internal meta-data to extract the requested columns.
3. The "child" columns in the table as seen on the web interface is not part of the main query, but are separate queries that are executed once for every row in the query. These queries are not sent to the exporter since they not part of the "current state" information.

To solve this issue would require major changes in the way the tables are generated as well as in the exporter plug-in.

Maybe we should create a special export that allows inclusion of child and/or parent items?
