APEX 4.0 - error building Gantt chart?

Question

Hi everybody
When I build a Gantt chart in apex.oracle.com, start & end dates show no real dates, just the text 'dd.mm.rr'.
My query follows:
select
null as link,
description as task_name,
task_id as task_id,
null as parent_id,
start_date as actual_start,
end_date as actual_end,
progress as progress
from PENDING_TASKS;
Any ideas?

Hi Oscar,
For Gantt charts, by default the Application Date Format will be used to format dates on your Gantt chart. If an application-level date format isn't specified and neither is a Gantt Date format, via the Chart Attributes page, then the NLS_DATE_FORMAT will be used to format dates on your Gantt chart. If you wish to define a date format via the Chart Attributes page, edit your Gantt chart, and update the "Date Format" item in the Gantt Settings region. For example, on this example on apex.oracle.com - http://apex.oracle.com/pls/apex/f?p=36648:4 - I've set the "Date Format" to *%dd.%MMM.%yy*, which uses the required AnyChart format specifiers, as outlined in AnyChart documentation, specifically in the Formatting Parameters List: http://www.anychart.com/products/anygantt/docs/users-guide/locale.html?fromtree#list.
Post-4.0 release, I did identify an issue with the popup associated with the "Date Format" item on the Chart Attributes page, and bug 9861439 can be used to track this issue. A fix for this issue will be available in our next release, but in the meantime you can enter dates into the "Date Format" text item, ensuring you use the AnyChart format specifiers outlined in the documentation I've included a link for above e.g. *%dd.%MMM.%yy*.
I hope this helps.
