java.lang.ClassCastException: jgrouse.jgdoc.elements.DocElement cannot be cast to jgrouse.jgdoc.api.IContainerElement

[kwek]

Hi im trying jgrousedoc against some of my company projects but for
almost every it ends up with the the cast exception. I also get this
when settings inputDir.default to a fresh yui installation. Anyone
know what can be the issue? thanks.

Wow! That's a good one. Will take a look at it this evening.

Note that even without that exception you would be out of luck re-
creating documentation for YUI - their documentation syntax is
different from jGrouseDoc, although quite close.

Regards,
Denis

Well yeah we base all our classes on the YUI framework but we are
flexible in the documentation syntax. I just gave YUI as an example
that even that wont run. I hope you can reproduce the errors else let
me know. Good luck and thanks :)

[denis.r...@gmail.com]

I was able to reproduce it. The first-phase fix would be a proper
handling of it (i.e. issue user-friendly error), but I am also
thinking about supporting YUI syntax,

It is quite unlikely that you would experience this problem if you
would stick to jGrouseDoc syntax.
