RE: [Dynapi-Widgetdev] Events fire all over the place on subclasses

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

We do not need to get nasty and therefore I need to make one thing clear.
I have not misunderstood. On the contrary, I am all FOR the project, and
appreciate what's available as building blocks. I have been using the API
since Dan wrote the first version and have never expected anything more
than what was already there. I never had the time to contribute to
the project, and maybe that time has come. Sadly, I have not been involved
with the 'Event' side of things which seems to be involved right done to the
core and I do not want to mess around with that.
Thanks for your help.

In case you misunderstood, this is open-source software, distributed under
the GNU license.
In this case that means that any effort you, or anyone, put into the project
is entirely voluntary, and unpaid.
Basically we all need a robust tool for dhtml, and do our bit to contribute
as we can.
Let's leave who can help as an open question, they all read this list, and
whoever can will take a look.
It's been registered as a bug, so will be tackled sooner or later.

It seems pretty basic to the whole inheritance idea that this should work,
but obviously something went wrong with the event listeners.
