Calendar display with custom table I am trying to show a calendar page with records stored in a custom table, using the Calendar module.

The table has been integrated with Views using hook_views_data. I also implemented hook_date_views_extra_tables and hook_date_views_fields to identity the relevant date fields to the Date module.

So far, I can create a new View with Calendar format (style plugin). When I add the Date: Date contextual filter (argument), I am able to see the field I specified in the hook_date_views_fields. So far so good.

Now when I save the view and show it, no calendar shows. When I get back to edit the view, the Date argument has been replaced with a "Broken/missing handler" notice.

Has anyone succeeded to show a calendar from a custom table?

N.B. This issue was created for the same purpose but it looks like the OP did not pursue it (or at least did not update it).
The reason for this problem was that the date argument handler was crashing. I had placed the implementations of the date hooks inside mymodule.views.inc, instead of mymodule.module. Duh!
