I'm upgrading a CMS version 9 to 10. For some properties we are using backingtype PropertyDropDownList and Custom property type to hold the data (EPiServer.SpecializedProperties.PropertyDropDownList). This works well in CMS 9, but presentation in 10 is not displaying the data. Other dropdownlists are working correctly. I have added <clientResources debug="true" /> to display debug-messages in the js-console, but can't see any issues.
Is there a good way to debug this?
(I have some screenshots, but unfortunately, I can't upload images here)
Which version of 10.x did you ugprade to? There was a bug in 10.10.5 (and maybe earlier) -- https://world.episerver.com/support/Bug-list/bug/CMS-8040 -- that was fixed in 10.11. Any chance that's related?
Thanks for answering. It is in fact 10.10.5 I upgraded to. This is the newest EPiServer.CMS.Core package v10 it seems. I will upgrade the other packages to newer versions and report.
Upgrading to 10.11 did the trick. Thanks for the answer!
