I am using Sitecore 7, in rich text editor I want to add a link to a pdf file, I used "Add a Link" option from the tool bar, I went to "search" tab which I believe is new in this version of Sitecore, I searched my item and inserted a link, Sitecore uses following format for insert the link
a href="~/link.aspx?_id=C3D29351D91C48E1A42C15E64060C547&_z=z
But the ID generated by the search function is not correct, it does not exist in the Sitecore database, If I manually edit the ID to the valid ID, it works, Why search function gives me a wrong ID?
See attched image as well.
I've created a ticket to the support yesterday about that issue, i'll edit my answer when i get an answer back (They can reproduce the error on a clean 7.2)
I've make a blog post which talk about the issue and give the ticket number (you can as the patch to the support)
