Re: Tapestry 5.2.1 upgrade woes

[Zubair Nuamaan <z....@googlemail.com>]

Hey, 

did you manage to find a fix for your problem?  I updated to use the new
Tapestry 5.2.1 and am getting the same error 

java.lang.NoClassDefFoundError:
org/apache/tapestry5/internal/services/RequestPathOptimizer

I also updated to chenelkit 1.3.0-sanpshot.

Thanks, 

Zubair

My intention is not to be harsh. I could not be harsh to anyone giving
me something as open and free. It's a gift. We have a proverb that you
don't check and complain about the teeth of a horse you got as a gift.
First of all it would be impolite and unfair.

We are just really unhappy if Equanda or Chenillekit are not updated
very soon and they don't work with latest Tapestry, since we wont be
able to go further and have them included, since our plans are to always
go with the latest of Tapestry, until we like it :)

Tomorrow we might be unhappy if there were some new exciting features in
latest hibernate, but tapestry-hibernate would not work with it and
there were no news or published plans of intention to make it work. In
that case we would be forced to change to something else.

Sad but true. Our project is an ongoing project with frequent releases,
used at university department - build by students for usage by students
and teaching and administration staff, it is going on since 1992 (as far
as I know, maybe even before) and it will probably go on in the future.
We are rebuilding all our applications that need new features (almost
all) with Tapestry, and we worked with JSP/JSF before that, Oracle
PL/SQL and Forms before that, MS Access before that and Clipper before
that. I don't know before that but I know that somebody did something
with punched cards some 30-40 years ago.

I am happy with Tapestry, and I lead the project for now. But for
example nowadays Kuali Project is grabbing forward in many US
universities and they have based their "Kuali Rice" framework on a stack
with another web/view layer technology, so it might become alternative
some time in the future, who knows. One has to always think outside the box.

Don't be too harsh on the 3rd party developers; we're still working
out what needs to be public and how.

We take the "internals can change at any time" vow seriously, which is
painful for any 3rd party library developers, as sometimes you have to
dive into the internal side to accomplish things.

I encourage any 3rd party library developer who does use internals to
get a dialog going on the mailing list (and then on JIRA) so that
necessary, stable, public interfaces can be created.

I don't think it's a framework problem but Chenillekit problem.
Imagine for example you are building an application with Oracle database
via JDBC but you are not using the regular published JDBC interfaces
that everybode else does, but some internal class that is part of the
exact implementation of the JDBC oracle driver. And Oracle decides to
implement it's own driver in a different way so your application will be
dead. Not a problem of Oracle.

This is a big problem for third party libraries. I already removed equanda
from my application to avoid these situations, now I'm tempted to let
chenillekit go too. I only use it to a very limited extent. It's been a
couple of months now with a rather stable 5.2, third parties should have had
plenty of time to sort out trivial compatibility issues.

I know you guys are all volunteers, and you do a great job. This is a
framework issue too, that version bumps cause third party libs to stop
working...

Re: Tapestry 5.2.1 upgrade woes

["Vangel V. Ajanovski" <aj...@ii.edu.mk>]

The chenillekit 1.3.0-snapshot that is found arround the net in maven
repositories is older version. The problem was fixed only 2-3 days ago.
You will have to wait till they publish a more recent 1.3.0-snapshot (it
should be dated later than 15th october).

What I did is
I downloaded chenillekit source from subversion (using the commandline
svn published on their website) and then
    mvn package -DskipTests=true
Some tests failed when building chenillekit-tapestry module, but I
disregarded it (thats why skipTests) and then I did
    mvn install
So all the JAR are installed in my local mvn repo and now my application
works and I don't have any other problems.

But from all of chenillekit I only use the Window component for popup
windows, so my case might not be representative.
I have also moved to Tapestry 5.2.2-SNAPSHOT and it still works.
