Thanks Konstantin,
I tried that approach on wtp 2.x (latest version from WTP or Europa
update sites) and the adapter manager is returning null.
So I used this instead:
Object configObject = def.createConfigObject
( javaFacetVersion, mavenProject.getProject().getName() );
if ( configObject instanceof IDataModel )
{
// This works in WTP 2.0
return (IDataModel) configObject;
}
else
{
// This is the compatibility layer for WTP 3.0
return (IDataModel) Platform.getAdapterManager
().loadAdapter( configObject, IDataModel.class.getName() );
}
Which works fine for WTP 2.x, but I'm not sure if this is the
intended pattern.
Is there any online resource where I can learn a bit more about this
API and its evolution?

Abel,
You should use Platform's adapter manager to "cast" the config
object to IDataModel rather than casting it directly...
Object config = def.createConfigObject( javaFacetVersion,
mavenProject.getProject().getName() );
IDataModel model = (IDataModel) Platform.getAdapterManager
().loadAdapter( config, IDataModel.class );
When this code evolved for 3.0, backwards compatibility layer was
added to help existing users, but the backwards compatibility layer
is bypassed by casting directly rather than adapting.
Let me know if you have further questions on this.

Subject: Re: [wtp-dev] WTP integration in the IAM project proposal
After the solution of https://bugs.eclipse.org/bugs/show_bug.cgi?
id=228452,
our users report a new problem:
java.lang.ClassCastException:
org.eclipse.jst.common.project.facet.core.JavaFacetInstallConfig
cannot be
cast to
org.eclipse.wst.common.frameworks.datamodel.IDataModel
This is caused by:
IProjectFacet javaFacet = ProjectFacetsManager.getProjectFacet
( "jst.java"
);
IProjectFacetVersion javaFacetVersion = javaFacet.getVersion( "5.0" );
Build buildModel = mavenProject.getModel().getBuild();
for ( IActionDefinition def : javaFacetVersion.getActionDefinitions(
Action.Type.INSTALL ) )
{
IDataModel model =
(IDataModel) def.createConfigObject( javaFacetVersion,
mavenProject.getProject().getName() );
// ^^ The above line causes the exception ^^
model.setStringProperty(
"IJavaFacetInstallDataModelProperties.SOURCE_FOLDER_NAME",
makeRelative( mavenProject, buildModel.getSourceDirectory() ) );
model.setStringProperty(
"IJavaFacetInstallDataModelProperties.DEFAULT_OUTPUT_FOLDER_NAME",
makeRelative( mavenProject, buildModel.getOutputDirectory() ) );
facetActions.add( new Action( Action.Type.INSTALL,
javaFacetVersion, null
) );
}
Is this an API change? If it is not, what's the right form of
adding the
java (or any other) nature using the 3.0 API? (We also need to
programatically add any other nature, so if there's an online
reference,
that would be great).

Although I replied privately (I don't know why I'm not receiving
