Description
I have chosen to use Confluence format to generate my maven site, primarily because of good table support.
I have found that doxia-module-confluence falls over with a NullPointerException if an empty cell is represented as a single space.
Confluence tables usually require this empty space, or they collapse the cell to be non-existant.
Information pertaining to this failure is below.
Let me know what more I can usefully provide.
Kind regards, Robin.
File: src/site/confluence/tables.confluence
Here is a 3 column table with headers, one row, and data in every column:
||One||Two||Three|| |1|2|3|
Now there is no data in column Two
||One||Two||Three|| |1||3|
Now there is a space in column Two
||One||Two||Three|| |1| |3|
