I have a problem on a SharePoint 2010 site. I have lists which contain Lookup fields. When I perform any action on the site that causes a custom dialogue to be displayed, the lookup fields become blank.
Here's what I mean:
Initially the lookup field is fine
Then we perform an action that results in a custom dialogue
After the dialogue is closed the lookup stays blank
It is important to note that the dialogue is coded to refresh the page when it is closed, but this does not get the lookup field to display correctly. A hard refresh does get it to display correctly though.
