[Solved - scroll down]
Hello
I've created a Portal linked to CRM D365.
I've got a page with an Entity List, which displays fine.
Selecting a record from the Entity List opens the Entity Form on its own page.
That last step works fine, but only when the Entity List view only contains 1 record. As soon as the List contains 2 or more records, I get an error when trying to open a record.
The error says "sequence contains more than one element" and a load of other stuff that I don't fully understand.
I've tried playing with the settings of the Entity List or Form, but I've not found a fix.
Has anyone experienced this and found a solution? I'd be immensely grateful to hear your suggestions.
Like I said, when the List shows only 1 record, it will open just fine; but when the List shows 2 or more, none will open.
Thanks,
Pete.
