Good morning,

Using rqt_publisher I can't find the proper way to edit the content of a field (defined as uint8[4] essuMaxTemp ) in a custom message type. when I typed in : '\x00\x00\x00\x00\x00\x01' I get this folowing error message # error evaluating as "list" when I typed in [0,0,0,0] I get no error message but, it publish "essuMaxTemp: [91, 48, 44, 32]"

The contextual help indicate me to "enter en python valide expression" so I guess that only a little question of syntax but I can't find on the internet example of syntax to use.

Thank for helping. I think the answer to that question should be in rqt_publisher FAQ (where i first looked in)
