Error with PDF printing

Question

I have a report region whose query specifies a '?' for one of the query's columns aliases. Something like 'Is Temporary?". When I attempt to 'Print' the report rendered by this query the result is an empty PDF document with an error message .
If I remove the '?' from the column alias , the report prints fine !
Is this a known issue with PDF printing in APEX ?
I have posted an example at the OTN APEX site.

Varad,
Thanks for the workspace name, I would just remove your "Is Temporary?" alias name, there's no need for that, you can define your column headings on the report attributes page, and keep the column name as "temporary", so this query:
select owner ,object_name ,object_type ,created ,status ,temporary "Is Temporary?" from all_objects
should be:
select owner ,object_name ,object_type ,created ,status ,temporary from all_objects
And then edit the report attributes and define a column heading for your "temporary" column.
