Re: [qooxdoo-devel] How to add a property and function to a class from another js file

I would like to chime in and say that if you remove the ability to add properties to already defined classes it will completely blow my program up. I have added many properties to many objects and I do it at run time so that I don't have to manage my custom code as opposed to the SVN code. Right now I can simply update my local files with the SVN files and not worry about any local changes I have because all my custom code is done at runtime. If you remove the ability to do this it will cause a lot of pain to a lot of developers. There had better be a very good reason for this other then "you think it's a good idea". What would be the upside to removing this ability?

I just mention this, because this will not work in the future. The plans
for a new property system doesn't allow the dynamic addition of
properties to previously defined classes.

Maybe it's better to enhance the other properties to make it possible to
use them in a comparable way.

Cheers,

Sebastian
