Nested Blocks keep disappearing!!


I have a very strange phenomenon whereby when i add blocks to content areas in other blocks, a few minutes later they disappear. I thought i was going mad, but its reliably repeatable. I have never encountered this before and have no idea what could be happening? I even copied the database down to my local machine but that made no difference. Does anyone have an idea what might be happening?

Hi what version of Episerver are you running? I do remember a bug a couple of months back in the UI that would exhibit similar behaviour and updating to the latest and a hard refresh solved it.

I thought it was a websockets issue, but the problem is still there.

Assume this is production? Are you using load balancing? Are the remote events configured correctly if so?

Hi David,

No, it is not happening on Production, only on my dev environment. When i posted the error I thought that I was using ContentAreas, but its actually  IList<ContentReference>.

I am getting JSON errors in the logs, so i think its a problem with using IList<ContentReference>, and changes to EPi regarding the use of JSON in storing these types.

public virtual IList<ContentReference> Contacts { get; set; }

I have now decorated the lists with [JsonProperty], and they are not disappearing now - but all the references are gone, so I will have to put in all the data again when i deploy to production.

Hi Dejan,

Looks like that is the way to go!
