[Chandler-dev] Fwd: [Bug 12115] Confusing discrepancy between list views on Hub and Desktop

[Mimi Yin]

I am forwarding this bug to the Dev-List as I think it's an important  
usability issue we should address in the web UI for 1.0:

Background:

In the interest of performance, we currently only look 1 month into  
the future when loading recurring events into the Triage Table in the  
Chandler Hub web UI.

This means that the web UI won't display a recurring event under the  
following circumstances:

1. the recurring event *starts* more than 1 month into the future
2. you have deleted the next occurrence, creating a recurrence gap of  
more than 1 month
3. the recurring event recurs at an interval more than 1 month apart  
(e.g. annually recurring holidays)

Given that we will be shipping 1.0- Desktop with a shared U.S.  
Holidays calendar, out of the box, I think we need to make it so that  
at least Scenario #3 works well in the web UI.

 From Randy's comment below, it seems the amount of work required to  
correctly load "the next occurrence of a recurring event series" for  
all 3 scenarios is out of scope for 1.0

However, we can implement a smaller change that would take annually  
recurring events and look 1 year into the future to find the next  
occurrence.

Randy, even though Chandler doesn't support bi-monthly and bi-annual  
recurrence rules. We do support importing them. Would it be possible  
to simply expand this exception to include any recurring events that  
have a recurrence rule of more than 1 month?

Is this an accurate summary Randy?

Are we still missing any key scenarios?

I have logged a separate bug to track implementing a more general fix  
so that all 3 scenarios listed above will work: https://
