Error 404 with Calendar Overlay across 2 Web Applications (part 2)

Hi all,

This is the reply that I’ve received this morning from our Vendor concerning the Calendar Overlay issues between multiple Web Applications: “it’s by design”.

So, no fix can be expected for this at the moment.

Therefore, I recommend educating the end user to open the item in the correct Web Application when needed.

You can find hereunder the complete explanation:

Hello Marc

As I also could repro the issue, MSFT did further research and found that this behavior is ‘by design’.

The issue has been addressed by the product group earlier and this was their answer :

It turns out it is by design:

=====================

We have conducted a thorough investigation into this matter and have determined the issue is Design Change Request in a feature area of substantial complexity. This complexity precludes making changes in this area outside of a major release.

The SharePoint calendar aggregation feature was designed to aggregate calendars within a single web application.

The calendar can aggregate across alternate access mappings, but not across apps. The alternate access mapping support did, however, make it appear that calendars could be aggregated across multiple web apps, but that is not a supported scenario. Adding support for cross web application calendar aggregation would involve significant feature work and as such, is not possible in a QFE.

Microsoft carefully reviews all Hotfix requests, as each code change must maintain or improve both quality and stability of the product.

In this instance, the risks to product quality and potential for destabilization are too high to permit changes in this area outside of a major release.

We thank you for bringing this issue to our attention and continuing to work with us on improving our products for customers worldwide.

The response is actually coming from the product group and they have no ETA on this nor if it will be fixed or not in future releases.

Voilà.

Error 404 with Calendar Overlay across 2 Web Applications (part 1)

Hi all,

Last week, I received a mail asking me if there was an issue with SharePoint.

The reported problem was that the client got an “Error 404” page when opening an item in her Overlay Calendar.

So, first thing first, is to reproduce the issue;

The client is using a calendar in her SharePoint Site (let’s call it TT2013MMA from the shpTeamCalendar Web Application).

Then she added the calendar of another site (let’s call it WW2013MMA from the shpWorkCalendar Web Application).

All is working like a charm, as the items of both calendars are correctly added, named in the TT2013MMA Calendar.

The problem start when you click on one of the items.

If the item is from the same calendar (the TT2013MMA), the details of this item is opened and can be reviewed/modified.

If the item is from the calendar located on the other Web Application (WW2013MMA), we got a nice looking 404-Error page not found.

I made some research, and I notice that doing calendar overlay across multiple Web Application gave the same problem.

http://social.technet.microsoft.com/Forums/sharepoint/en-US/7ad58dab-a707-4bf6-ac1d-3fbe20fcfe44/calendar-overlay-across-multiple-site-collections

So, at the request of Microsoft, I’ve reproduce with success the issue in my Test Farm with 2 brand new Web Applications.

Server name : test.domain\TestServerName

Tests were done with in both sites: test.domain\MyLogin (Mathot Marc)

Calendar working with Overlay : http://shpWorkCalendar-test.domain/sites/WW2013MMA

Calendar of the second Web App : http://shpTeamCalendar-test.domain/sites/TT2013MMA

The Overlay Calendar is on http://shpWorkCalendar-test.domain/sites/WW2013MMA

And the item added from this calendar are in green.

The overlayed calendar (from the second Web Application), is on this site : http://shpTeamCalendar-test.domain/sites/TT2013MMA

The items from the TT2013MMA calendar are in yellow.

Calendar using the Overlay in the shpWorkCalendar Web Application:

 Calendar from the second Web Application : shpTeamCalendar

Now, let’s check the URL pointing to the different items in the shpWorkCalendar:

                The URL is correct :

-          Web Application of the Calendar : shpWorkCalendar

-          Site (WW2013MMA) is created on the shpWorkCalendar Web Application

The URL of the item is incorrect:

-          Web Application of the calendar is shpWorkCalendar

-          Site (TT2013MMA) is created on shpTeamCalendar and NOT on shpWorkCalendar.

SharePoint is pointing to the source Web Application (shpWorkCalendar) instead of the correct URL where the item was created.

The correct URL must be : http://shpTeamCalendar-test.domain/sites/TT2013MMA/Lists/Calendar/DispForm.aspx?ID=3

Same fort his second item :

                The correct URL must be : http://shpTeamCalendar-test.domain/sites/TT2013MMA/Lists/Calendar/DispForm.aspx?ID=2

And also for the last one:

               The correct URL must be : http://shpTeamCalendar-test.domain/sites/TT2013MMA/Lists/Calendar/DispForm.aspx?ID=1

  

Result on clicking on the NOK item, is a Error-404 page.

My vendor already made testing, and had the same results as mine.

Now, waiting for the Microsoft specialist to make the same tests, and give his feedback.

So, as far as from now, I have no solution, nor workaround.

... to be continued...
