I made a TV with the input Option check box and the Output type URL with some values like Display Text and Title.
Selecting the TV check box generates the desired Output but "unchecking" it generates the text "Array" in the frontend of the website.
Maybe this is a known bug but I wasn’t able to retrieve the bug-file about it.
There is a workaround by adding a "chunk" as the value. With in the chunk the desired URL.
Would you file that as a bug using the bugs & requests link at the top of this page?
