hi,


i have readed the help document of eclipse concerning ocl and xtext .
now , i want to apply the OCLinEcore tutorial.
i have installed the ocl plugin and when i go to my Ecore model on src-gen and when i click on it and try to open it with OclInEcore editor i have this error :

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

can somebody knows why i ge this error?

Hi

If you are using a Helios or Indigo release or service release it should
be ok.

If you are using a Juno pre-release make sure that you are using OCL and
Xtext of the same vintage.

Hi

You'll have to share some OCL and Xtext plugin ids with us.

Xtext is quite lenient about running a variety of versions on different
platforms.

OCL was very strict, but is a bit more generous in Juno.

I'm fairly certain you have an unwise plugin combination.

Hi

OCL 3.1.2 is an Indigo maintenance release.

Xtext 2.1.* is the Indigo release.

Xtext 2.2 and 2.3 will run on Indigo, but they are not Indigo releases.
It looks as if Xtext has a binary compatibility problem.

For Juno there is OCL 4.0 and Xtext 2.3, both of which will run on Indigo.

HI

Sorry; I'm forgetting the excitement already.

OCL provided a 3.1.2a build specifically to fix this problem. See
http://www.eclipse.org/modeling/mdt/downloads/?project=ocl. Since the
problem does not affect Indigo users, it was not appropriate to rerun
the final Indigo SR2 build.

Ultimately the problem is that Google moved a package from
google.collect to google.guava and the consequent schizophrenia cures
have been taking time to ripple down the dependency chains. Xtext 2.2
allow switched and so is not strictly Indigo compatible.

thks ,
then if i well understood the best way to fix and prevent problems is to use juno?

now i have downloaded juno and installed it and all the neccesary plugin , now when i run my .mwe2 file as a wrkflow , i have the following error:
 It is highly recommended to use ANTLR's parser generator (get it from 'http://xtext.itemis.com/'). 
As an alternative to ANTLR you could also use the alternative implementation shipped with Xtext.
To do so use the generator fragment 'org.eclipse.xtext.generator.parser.packrat.PackratParserFragment' in your mwe2 file instead.(Element: -UNKNOWN-; Reported by: -UNKNOWN-)
java.lang.RuntimeException: Problems running workflow org.xtext.example.GenerateProject2:

Hio

No. My first message said use Juno.

My second message said OCL 3.1.2a was there for esxactly your problem.

Your specific error is a failure to follow the console download
instructions you need precisely "y" then "<Enter>".
