EMF target model with xmi:id [message #637116]

Thu, 04 November 2010 05:28

Eclipse User

Hello,

when I took a look at the resulting model of my ETL transformation (with a simple text editor) I was suprised that none of the elements got equipped with an xmi:id. I need these ids in my model, because my GMF editors expect them. Is there a switch to in the load task to have them set in the model?

My load task looks like that:

<epsilon.loadModel name="myModel" type="EMF">
	<parameter name="modelFile" file="./out/out.model"/>
	<parameter name="metamodelUri" value="http://myuri.com"/>
	<parameter name="readOnLoad" value="false"/>
	<parameter name="storeOnDisposal" value="true"/>
</epsilon.loadModel>

Thanks for your help!

Hi Henning,

Unfortunately, there is no way to do this in the current version of
Epsilon but I've figured out how to do it so if you could file an
enhancement request I'll fix this and release a new interim version shortly.

Cheers,
Dimitris

Hi Henning,

Thanks for filing the bug report! This has been fixed in the latest
interim version (0.8.9.201011041158).

As mentioned in the bug report, to turn on XMI IDs for a model M, you
need to add the following line to your code:

M.resource.useXmiIds = true;

Cheers,
Dimitris

Hi Dimitris,

so far I used the file extension ".model" as a my target model output to quickly access the result in the Exceed editor, however, to access the transformation model in my own GMF Editors I need my own "filetype". But the change of file type in the ANT script causes the following exception:

org.eclipse.core.runtime.CoreException: /Users/henning/Documents/workspaces/diplom/de.hager/launch.xml:31: Property 'useXmiIds' not found in object org.eclipse.gmf.runtime.emf.core.resources.GMFResource@fc925db

I'm also still experiencing general problems with my GMF editors right after the transformation process, which are gone after restarting eclipse. Even though, I didn't register the relevant meta mode as suggested in this post.

Thanks for your help,

Henning

Hi Henning,

If you're using a generated implementation of Resource to load your
models (i.e. you've generated code from your Ecore metamodel) you'll
need to take care of XMI ids there by overriding the useUUIDs() methods.

If the GMF problems persist after you've fixed this, could you please
zip and send me a configuration that I can use to reproduce this at
epsilon.devs gmail com?

Cheers,
Dimitris

Hi Dimitris,

I realized that my model code does not override useUUIDs, in fact, I could not locate any class that is implementing Resource.
However it works all just fine, when the GMF editors create the XMIs. So, I figured that GMF is taken care of that for me. So again, I removed all loadings of my meta models as you suggested and it works all good now Smile

Thanks for your patience!

Henning
