[VW 7.9] cannot override method

You can no longer have a class override and a method override for the same

class and package.

1. For a class Foo initially defined in package A, create a class override in package B.

2. Select one of Foo’s method in package A and do a create override, putting it in package B.

3. Notice the method definition did not move.

4. Select the override tab and notice that package A appears on both sides of the override comparison.

Re: [VW 7.9] cannot override method

Terry,

Here is a serious query: Did this ever, in the RB is the browser world, work?

There may be a major hole in our "Model" mechanism that I've never gotten a full handle on.

You can no longer have a class override and a method override for the same
class and package.

1.       For a class Foo initially defined in package A, create a class override in package B.
2.       Select one of Foo’s method in package A and do a create override, putting it in package B.
3.       Notice the method definition did not move.
4.       Select the override tab and notice that package A appears on both sides of the override comparison.

Question: Does the same definition appear in both sides? My impression is that the override is there, and actually working, but I could be wrong.

And So It Goes

Sames

Re: [VW 7.9] cannot override method

There is a fix in 7.8 to prevent packages from multiply overriding a method,

page 1-22 of the 7.8 release notes. It looks like it is too aggressive.
