Yes! It happens to ExtPascal each time ExtJS releases a new version.

It's sad but true. While I believe it can be avoided for any common
purposes, but in some advance optimization it just can't be. Just like the
way we're using assembler in pascal. But it should be 1-5 percents of all
cases.
I have the first server-side things ready, namely: the server-side
interface to ExtJS's data API. It's a breeze in FPC, and lightning fast.
It would be better if the server side interface is plain and independent to
any JS framework API. The interface result then could be "translated" to
any client side API, or SOAP, or WST, or whatever is required format by the
client side framework using some kind of API dictionary or something
similar.
Interesting. I'm currently working on a project to do Adobe Flex through
ObjectPascal and I've been working to generalize as much of the interface for
widgets as possible so that it could be compatible with some JS framework
later on as well, like OpenLazlo does in concept. Though honestly, I'm only
interested in doing flex right now personally, but nice to have options :-).
Another thing that I've been careful to do and I think is important is
abstracting the widget-framework away from any particular protocol or
transport framework so I could easily compile it to stand alone, apache_mod
or ISAPI using any of the technologies available to freepascal or Delphi.
Currently there is no ISAPI interface, but this is planned for the near future.
Michael.
