I have been having problems with content assist on dojo widgets. For example, i added a dojoradio group as follows:

RadioGroup DojoRadioGroup{
        vertical = false,
        options = ["Single Account","Multiple Accounts"],
        selected = "Single Account"
    };

I then try to use content assist in an onclick function and it doesnt work (either ctrl+space or context menu option)

function Button_onClick(event Event in)
    RadioGroup.
end

When i put my cursor on the text, i get the following popup error. Not sure if this helps.

IWN.SYN.2112.e 264/4 Syntax error. Input is not recognized as "settingsBlock"

I've found and fixed this. Thanks for reporting it. I will make sure you get the fixtest.
