Accessing library marked as "Unset (mixed content)" crashes EMC

[AdrianW 1058]

I have a couple of top level libraries which consist of some online and some offline content.

 

This is actually caused by libraries that are marked as "Unset (mixed content)" - I can no longer browse any of these from EMC.

 

There's been a change to the dev server that is now causing EMC to crash when I enter into one of those libraries from the EHS.

 

I've noticed that issue is different on my two installs of EMC (both on 286) - on Win 10, EMC crashes when entering into the library. But on my main Win 8 HTPC (where Emby Server is also installed) EMC crashes when just scrolling onto the library.

Turns out that it's not offline content - it's any library marked as "Unset (mixed content)" that I can no longer access from EMC.

Can you please find and post the Windows Event log error?  Thx.

Hopefully this is what you're after:

Luke, is the Display Prefs ID no longer being filled in for these items?  That value should never be null as the server should derive some sort of ID for all folders.

 

Or, is this due to a change in the model?

 

Adrian, did this get released into the stable version yesterday?

Ah, I had this very late last night (half asleep) forgot to report today. Looks like you've found it but for info I'm on Dev everything and it was indeed my unset folders causing this.

[AdrianW 1058]

I'm on dev as well - it was a dev server update around 5th or 6th November.

 

Still occurring on 3.0.5791.23954

i've looked and i don't see how it could be missing. is it possible there is a url where you're forgetting to request the DisplayPreferencesId field? or is it possibly coming through as Guid.Empty in some cases? 

[ebr 16169]

I don't know why it would be different with the only change being on the server side.

 

More likely a model mis-match type of issue.  Did anything change in the model?

Hi guys, just updated to Server 3.0.5792.25141 and EMC 3.0.287.0 and Unset folders are now behaving, thank you   

[ebr 16169]

Please make sure indexing is still doing what you expect.  Thanks.

Working for me also.
