Table exporter fails with NPE when exporting spot data

[Jari Häkkinen]

I am trying to export spot data from a table listing. Clicking on the 'Export...' button and selecting all columns and immediate download simply displays 0% with no progress. Trying to perform the same export but to a file gives the below stack trace. Status message is simply 'Error:'

I can confirm this in the trunk. The error happens even if I only select a single column and it doesn't seem to matter which column.

This issue was probably caused by changes for ticket #1343 [5299].
