Hallo,

i am facing a problem after migration of my oaw 4 project to oaw 5 project.

the class SimpleJavaModificationComponent doesn't exist anymore in oaw 5. so i found the thread in http://www.openarchitectureware.org/forum/viewtopic.php?show topic=14146&lastpost=true#15202 and try to created SimpleJavaModificationComponent .

unfortunately i got the cast-exception:

1. my SimpleJavaModificationComponent:
import org.eclipse.emf.mwe.core.WorkflowContext;
import org.eclipse.emf.mwe.core.issues.Issues;
import org.eclipse.emf.mwe.core.lib.WorkflowComponentWithModelSlot;
import org.eclipse.emf.mwe.core.monitor.ProgressMonitor;

public abstract class SimpleJavaModificationComponent extends
		WorkflowComponentWithModelSlot {

	private Object modelObject;

	@Override
	protected void invokeInternal(WorkflowContext ctx, ProgressMonitor monitor,
			Issues issues) {

		String strName = getModelSlot();
		modelObject = ctx.get(strName);

		if (modelObject == null) {
			issues.addWarning(this, "content of modelSlot " + getModelSlot()
					+ " is null.");
		}

		doModification(ctx, monitor, issues, modelObject);
	}

	protected abstract void doModification(WorkflowContext ctx,
			ProgressMonitor monitor, Issues issues, Object model);

}


2. my ModelTransformer Class
public class ModelTransformer extends SimpleJavaModificationComponent {

	protected void doModification(WorkflowContext ctx, ProgressMonitor monitor,
			Issues issues, Object model) {

		ModelImpl dm = (ModelImpl) model;// <---caused an exception!!!
		}
}


during debug i found out the Object model ist type of AnyTypeImpl. my question is how can i cast the AnyTypeImpl to ModelImpl?

thanks very much for your help.

Hi,

are you sure that there is a Model (you should cast to the interface always) in the slot? can you post your complete workflow?

thanks a lot for your quickly answer

i am pretty sure that is my model. and here is the snipshot of my workflow:

........
<component class="namespace.ModelTransformer">
  	<modelSlot value="model" />
</component>
.......

Hi,

your exceptions says there is a org.eclipse.emf.ecore.xml.type.AnyType in the model solt so one more: how to you get the model? can you plase post your complete workflow?

Hi,

And is it running now? is this the current workflow - the namespaces in your workflow seem a bit old.

Hi Ming

AnyType is the basic XMI element that Xtext uses until it can resolve a
proxy, so a CCE on an AnyType justvtells that a proxy resoluation failed
so your models/namespaces are incompatible or unresolvable.

If you search all ResourceSet.resources.errors you may find that
something is trying to tell you something; Xtext fails to explicitly
diagnose deep proxy resolution failures.

Regards

Ed Willink

Hi Ming

Sorry wrong newsgroup. Nothing explicitly to do with Xtext, but the
proxy issue may still be relevant.

Hi Edward,

Thx for your help!

i have a question. i try to debug in eclipse and see the Issues issues in
protected void doModification(WorkflowContext ctx, ProgressMonitor monitor, Issues issues, Object model) {
...
}

doesn't occupied any objects.

is this problem, you mined? if yes, how can i trace whether proxy issue works?

Hi Christian, Edward,

it still doesn't work. here is the link to the branch of source:
https://dromdary.svn.sourceforge.net/svnroot/dromdary/branch es/migrationToEclipse36/

it will very kind of you, if you can check it out!

the same source works with oaw 4.3 + eclipse 3.4. we became the error because we want to migrate the project to oaw 5 (integrated into eclipse EMF )+ eclipse 3.5.

please checkout the souce and open it in the eclipse 3.5 (Eclipse Modeling Tools) edition and run oaw in the project common.generator/src/main/resources/workflow.oaw. you can see the cast-exception in the console.

Thanks a lot for your kindly help!
best Regards
~Ming

Hi,

using the latest (and mwe compatible ea exporter) from here: http://uml2ea.blogspot.com/ it works with a dummy eap sample file.

The problem is the UML model version, which is 2.1.0 declared in the model file. The actual installed UML plugin version I assume is >= 3.0.0 in a normal Helios distro. So this NS URI must be mapped. Unfortunately this is not all for UML 2.1.x models, since the have to use a special Resource implementation (using the extensionMap mapping) and additional mappings for the UML21_2_UML.ecore2xml, which is referred as platform:/plugin URI.

Unfortunately it is not that easy to map this URI to a file unless it is unpacked from the org.eclipse.uml2.uml package and it would be better to map it from the plugin. This cannot be done in the workflow, since the plugin location is not known. But it can be solved by deriving the Mapping class as follows:

package org.eclipse.xtend.typesystem.uml2;

import org.eclipse.xtend.typesystem.emf.EcoreUtil2;
import org.eclipse.xtend.typesystem.emf.Mapping;

public class UML212URIMapping extends Mapping {
  public UML212URIMapping() {
   setFrom("pltform:/plugin/org.eclipse.uml2.uml/model/UML21_2_UML.ecore2xml"/>
   setTo(EcoreUtil2.getURI("model/UML"1_2_UML.ecore2xml"));
  }
}


And then this mapping must be used in the UML2 Setup in the workflow:

<bean class="org.eclipse.xtend.typesystem.uml2.Setup" standardUML2Setup="true">
  <extensionMap class="org.eclipse.xtend.typesystem.emf.Mapping">
   <from value="uml"/>
   <to value="org.eclipse.uml2.uml.resource.UML212UMLResource"/>
  </extensionMap>
</bean>


Quite tricky, but necessary for that UML dialect. With UML models declaring other NS URIs than UML 2.1 there should be no problem.

I think it is worth adding this special mapping or a specific version property to the Setup class. I will open a bugzilla for that.

Kind regards,
~Karsten

Hi, Christian, Karsten, Edward

thanks a lot for your kindly helps!

i resolved the problem with the new component4oaw. it was the problem of uml 2 compilable from the c4oaw 1.6.1. with c4oaw 2.0 rc3 is my project runnable.

thanks again for your helps!
