Re: [henshin-dev] Problems with source metamodel
Hi Christian,

Here you have the stack trace from eclipse:

I get an error when i try to run the test unit from "generateHenshinRules.henshin", 
java.lang.AssertionError: Error executing unit 'test'

For debugging, i can debug the resourceSet and the resut But since the program terminates when i get this AssertionError, i'm finding it hard to debug.

And i messed up abit on the Resource model, in "TranslateToHenshinRules", it should be 

Resource model = resourceSet.getResource("tra1.xform");

But i still get the AssertionError when running the test unit.

Cheers,
Petter

Dear Petter,

Hello everyone,

I'm currently working with trying to set up a model to model transformation environment. For doing this i want to use Henshin to translate a set of transformation rules into Henshin rules.

I am having a very similar problem that Jens had,


But for some reason i cannot get it to work. I import my source metamodel to my Henshin module. This metamodel has a root element, named Transform. The file itself uses an "example.xform" extension. 

<?xml version="1.0" encoding="ASCII"?>
<xmi:XMI xmi:version="2.0" ....>
  <transform:Transform>
               ....
               ....
               ....
  </transform:Transform>

So i have a simple Henshin rule where i only have one preserve action, namely a Transform object, but then i get an AssertionError on my rule.

Where and when does the AssertionError occur? Do you get an error message? How does the stack trace look like? Did you try to debug it?

Best regards,
Christian

 
So that tells me that i am having a problem with loading the instance of my source metamodel. I cannot figure out what seems to be the problem. I have tried to register the extension to the resource set,

resourceSet.registerXMIResourceFactories("xform");

But i cant figure out what i am doing wrong?

Thank you in advance,

Petter
