RAP 3.0? [message #1403999]

Hi,

I see there is a RAP 3.0 planned, apparently for December. This implies
API breakage. How can I find out more about how this will affect me,
i.e., how will EMF's RAP integration be impacted?

I assume the Mars release train will include some RAP 3.x version and I
assume that the Luna service releases will include RAP 2.3.x releases or
perhaps a 2.4.x. Are these good assumptions?

Regards,
Ed

Hi Ed,
yes... Luna service releases will include RAP 2.3.x releases. Mars
release train will include RAP 3.1 version. RAP 3.0 is planned for
December. About API changes - all deprecated classes (API) will be
removed (most of them are already removed from master branch, upcoming
3.0M1). You could give the latest nightly [1] a try to see how EMF's RAP
integration is affected. As usual, we will provide a RAP 3.0 migration
guide (similar to 2.0).

.... and in RAP 3.0 we discontinue IE7/8 support and maybe some other
(non CSS3 based) older browsers.

Good Morning Ed,

you are correct in your assumption that RAP 3.0 will contain some breaking API changes. When we did the last breaking upgrade to RAP 2.0 we maintained a document with all our changes, but this document is not yet ready for 3.0. The same applies for the planning: I will try to summarize the already known changes in a document and/or in the project plan.

All our scheduled versions can be found here:

https://projects.eclipse.org/projects/rt.rap/documentation

Luna will see updates to our currently released 2.3 stream, i.e. Luna SR1 will include RAP 2.3.1, and Luna SR2 next year will include 2.3.2. Even if we could update theoretically in SR2 to RAP 3.0 we don't have any plans in this direction.

RAP 3.0 is planned for this December, and (similar to RAP 2.0 a few years ago) we are planning to contribute RAP 3.1 to the Mars release next year.

Hope that helps for the moment.

Thanks,
Markus

Ivan,

Thanks for the info. Our builds are pointing at RAP's nightly build,
and those have been picking up 3.x, which is why I noticed. (That's even
the case for the emf-maintenance build which is targeted for Luna SR0,
so that's bad.) At least the builds themselves haven't been failing, so
that looks promising.

Hi Ivan,

I am currently trying to migrate from 2.3 to 3.0. Do you know when the RAP 3.0 migration guide will be available?

Best,
Matthias

Hi Matthias,
I hope, it will be ready before RAP 3.0M3. Since them, do you have any
particular problems during the migration? If yes, ask here and I'll try
to help you. In RAP 3.0M1 all deprecated API have been removed -
basically in lifecycle package. The replacement is the new Remote Object
API introduced in RAP 2.1.
HTH,
Ivan

Hi Ivan,
thanks for your answer.

We wanted to have callbacks before and after a http request. Therefore we registered a PhaseListener:

RWT.getLifeCycle().addPhaseListener(impl)

which called our two methods:
a) beforeHttpRequest()
b) afterHttpRequest()

How would I now implement this feature? Also with the Remote Object API?

Hi,
the replacement (not completely) of PhaseListeners is MessageFilter,
which is currently internal, but we want to make it API for 3.0 release.
The concept is similar to servlet filter and can be added to
ApplicationContext(Impl). Please note that the filter is processes
outside the UI thread (SWT compatible mode) and there is no access to
display/widgets in it.
HTH,
Ivan

When I want to add a MessageFilter, I need to have the ApplicationContextImpl?!

Is this the right way to obtain it?

ApplicationContextImpl impl = (ApplicationContextImpl) RWT.getApplicationContext();

Yes... When we make it API the cast will not be needed.

Hi Ivan,
thanks for your help, I was able to migrate.

I have one more question:
we use the following code

WidgetUtil.getAdapter(tree).getId()

Is there now another way to get the id?
