[Caml-list] "abbreviation of class expands to type.., but is used with type.."

["Walter B. Rader" <wrader@OCF.Berkeley.EDU>]

I'm getting a vague error message when trying to compile my project in
OCaml.  The summary of the error message is in the subject of the message,
again summarized here:

"The abbreviation widgetBase expands to type ...
 but is used with type..."

(Full text appears below.)  The error apparenty appears on line 140, which
is the start of the definition of the class.  Therefore, I have no idea
where I'm using the class incorrectly.

Any suggestions?

Thanks,

Walter Rader
