I have a problem regarding broken links in Sitecore.
Our tree is filled by a console application with data from an other, older cms through the Sitecore item API.
We have products that are linked to Categories with a multilist. When an editor deletes a category, sitecore should give a popup to handle the broken links. This he does in 1 of the 4 cases. In the other cases Sitecore does not give a popup and the category deleted still appears in the multilist as "Not in the selection list".
Is there something wrong with how we insert the items or is it just Sitecore not being able to handle large amounts of data in the linking story?
FYI: we have around 160 categories and more than 1200 products.
Thank you in advance.
@Marek Musielak 's comment did the trick. Rebuilding the Links Database is the best way to ensure no broken links.
