We have a strange problem with properties of the LinkItemCollection type, when it's used in a loadbalanced environment. If we publish the page with the linkitemcollection property on server 1, the page renders correctly with the list on links on server 1. On server 2 though, the page renders with no links, as if the property was null/empty.
If I then re-publish the page on server 2, the page renders correctly on server 2, but not on server 1 (property is null).
To make this even weirder, if you're in edit mode and view the page, this problem doesn't occur. Then the page renders correctly on both servers, independently of on which server you published the page.
This problem occurs for all LinkItemCollection properties, and on two different sites (with different codebase). Both theses sites uses CMS5 R2 SP2 and Relate+ 1.0 SP1 in a loadbalanced environment (obviously ;-))
