[Pierre]

The first snapshot of Mvp4g 1.3.0 is now available. It includes the
navigation confirmation (issue 46) and lifecycle presenter (issue 47)
features and also issue 50 correction. You can find it in the download

-token generation for hyperlink (http://code.google.com/p/mvp4g/wiki/
PlaceService_130#Hyperlink_Token)

Did you take down the 1.3 snapshot? Only the examples are currently
in the download list ...

Thanks Philippe :)

I didn't add the snapshot to the download section but you can retrieve
it either by downloading the examples (the snapshot is in the lib
directory inside any example) or thanks to Maven.

[John]

Sorry, of course it's in the lib directory - else the examples
wouldn't work :/

-correction of few bug correction including issues 55 & 56.

Let me know what you think and if you ever have any problem.

This is fantastic! Thank you so much, I'm upgrading to test this out now.

[Pierre]

A new snapshot of Mvp4g-1.3.0 is available. It includes an APT to
detect the most common Mvp4g errors directly in the IDE. You can take
a look at this page to see what errors can be detected and how to
configure Eclipse to use this APT: http://code.google.com/p/mvp4g/wiki/APT_130.

Let me know what you think and if you have any issues.

Thanks,
Pierre

[Dennis]

that's great - just set it up and works like a charm! thank you very
much! I especially like that it tells me that I forgot to add a event
handling method on a presenter which can produce hard to understand
errors when running the program.

Hi Pierre,

After updating locally in my eclipse from mvp4g 1.2.0 to the latest
1.3 snapshot which worked fine I checked in my changes to the SVN and
let the continuous build (hudson in my case) do its job but
unfortunately there it failed with many, many errors that go like
this:

[javac] /var/local/hudson/jobs/yadaydaa.../client/MainEventBus.java:
83: Invalid Event bus: ....MainEventBus can't be injected to
RootPresenter. Can not convert ...MainEventBus to E
[javac] public void start();

[javac] /var/local/hudson/jobs/..../RootPresenter.java:46: Invalid
View: ...MainPanel can't be injected to RootPresenter. Can not
convert ..MainPanel to V
[javac] public class RootPresenter extends
MyBasePresenter<RootPresenter.Display, MainEventBus> {

as I said before compiling and execution in my eclipse works fine. Do
you have any idea why this happens? Could this be related to the APT?
I'm afraid I have to revert to 1.2 again :-(

thanks for any suggestions!

Dennis

[Dennis]

just had an idea, maybe above problem is related to generics. My
presenter superclass looks like this:

public class MonoBasePresenter<V, E extends EventBus> extends
BasePresenter<V, E> {
...

and in the subclasses:

@Presenter(view=MainPanel.class)
public class RootPresenter extends
MonoBasePresenter<RootPresenter.Display, MainEventBus> {

public static interface Display extends IView {
...

maybe there's a problem in the way this is handled?
But it's till weird, why does it work when eclipse compiles it but not
when javac compiles it? rolling back to 1.2.0. for now. Please let me
know how I can further assist in debugging this or try out a new
build.

thanks,
Dennis

FANTASTIC ;)

Hi Dennis,

I reproduced your issue, it seems Eclipse and maven have different
java compilation. The error appears only with maven. I've been able to
correct the issue and I uploaded a new snapshot. I tested with a local
maven project and the error was corrected but I will validate with
hudson to make sure there is no more error.

I keep you updated,
Pierre

[Dennis]

Hi Pierre,

I think the difference is between eclipse's own java compiler
implementation and sun''s official java compiler (javac) which in my
case is used by hudson through some ant buildscripts (and I guess
maven uses it too).
I will try to test it again later on today.

thanks,
Dennis

[Pierre]

We tested the last snapshot on hudson (with maven) and it worked.
Sorry about this bug. If you ever have other issues, let me know.

Thanks,
Pierre

[Dennis]

great! It seems http://code.google.com/p/mvp4g/downloads/list is not
yet up to date with the latest snapshot. Where should I get it from?
svn?
I see there is one in
http://code.google.com/p/mvp4g/source/browse/maven2/snapshots/com/googlecode/mvp4g/mvp4g/1.3.0-SNAPSHOT/mvp4g-1.3.0-20110111.142313-8.jar?spec=svn876&r=876
but this is for maven - is there any difference to the normal one?

thanks,
Dennis

[Pierre]

Hi,

I noticed another difference between eclipse and maven/ant :/, I think
I will create a special jar for eclipse apt so that it's not used by
maven/ant (since it's not needed, see this message:
http://groups.google.com/group/mvp4g/browse_thread/thread/1a9e46797c481355#).

[Pierre]

A new snapshot is available. There is no new feature but the APT has
been moved to its own jar to prevent issues with ant/maven.

A new snapshot of Mvp4g-1.3.0 is available. This snapshot includes all
the features that will be available for the final 1.3.0 release. No
change will be brought to Mvp4g-1.3.0 (but bugs correction if any).

It includes:
-Use of historyName instead of the event's method's name for the
dispatch method (issue 60).
-Custom Place Service (issue 63, see doc:
http://code.google.com/p/mvp4g/wiki/PlaceService_130#Setting_a_Custom_Place_Service)
-Possibility to turn off history for the whole application, not only
for one module (issue 62, see http://code.google.com/p/mvp4g/wiki/PlaceService_130#Temporary_disable_history)
-Simplify conversion from event to token (issue 51, see doc:
http://code.google.com/p/mvp4g/wiki/PlaceService_130#Associate_an_History_Converter_to_an_event)
-Removal of XML support (issue 64)
-Possibility to set no start view for non-autodisplay child module
(issue 67, see http://code.google.com/p/mvp4g/wiki/EventBus_130#Start_View)
-APT: detect child/parent events error

You may have to bring some changes to your code when you move to this
snapshot:
-@Event: attribute 'historyName' has been renamed 'name' (see issue
60)
-dispatch, convertToToken and filterEvent now uses the event's name
and not its type. This may impact your code if you have named your
event (by default event's name == event's type) and uses one of these
methods.
-@History(convertParams=false) has been replaced by
@History(type=HistoryConverterType.NONE)
-@HistoryConfiguration has been removed. You can now define your own
place service and set it for your application thanks to @PlaceService
(you can look at
http://code.google.com/p/mvp4g/source/browse/trunk/examples/Mvp4gModules/src/com/mvp4g/example/client/main/CustomPlaceService.java
).

If you have any question or issues, let me know.

Thanks,
Pierre
