I added Text Area fields with HTML turned on for an object and when I try to output them in an HTML template report, nothing is being displayed. They are outputting data in a Tabular report so the entries are being stored but for some reason nothing is displaying in the HTML Template reports. I have tried using both {!field} and {!field#html} without success.
I'll take a look.
I do not confirm the issue: works fine in my test environment.
Rich text HTML may be conflicting with HTML on page. Please open HTML source, that may give some clue.
In case anyone else has this issue, it was occurring because I was referencing an object with multiple records without a loop to recursively go through each record. I didn't think I needed this as I was applying a filter so that only one record was ever returned but I did need it to get the HTML block to display.
You need a loop to reference multiple side of relationship.
