Re: Upgrade EGL from WDSc 6 to WDSc 7

The syntax changed on the EGL, especially the handler.

Ouch. Doesn't sound like backward compatibility was in mind???!! Could you
explain more?
There was significant syntactical change from V6 to V7. I mentioned it, and the response I got was that they just had to do it to support some of the new stuff, like rich UI and Ajax. Pure backwards compatibility can be a curse; just read about how complex Java generics had to be in order to preserve backwards compatibility.

I guess that IBM felt that the lesser of two evils was to break backward compatibility in order to implement the new paradigm correctly. This was a major shift and not undertaken lightly, and from what I understand they don't plan on any more of these.

However, if you want specifics, I suggest you go to the source. You've met most of the players, you can probably email any one of them.
