AADL Properties View on instance model #620

Closed reteprelief closed 9 years ago

reteprelief commented 9 years ago

When I open an instance model and then open the AADL properties view I get a class cast expression.

java.lang.ClassCastException: org.osate.aadl2.util.Aadl2ResourceImpl cannot be cast to org.eclipse.xtext.resource.DerivedStateAwareResource at org.eclipse.xtext.resource.DerivedStateAwareResourceDescriptionManager.internalGetResourceDescription(DerivedStateAwareResourceDescriptionManager.java:41) at org.eclipse.xtext.resource.impl.DefaultResourceDescriptionManager$1.get(DefaultResourceDescriptionManager.java:62) at org.eclipse.xtext.resource.impl.DefaultResourceDescriptionManager$1.get(DefaultResourceDescriptionManager.java:1) at org.eclipse.xtext.util.OnChangeEvictingCache.get(OnChangeEvictingCache.java:77) at org.eclipse.xtext.resource.impl.DefaultResourceDescriptionManager.getResourceDescription(DefaultResourceDescriptionManager.java:59) at org.eclipse.xtext.resource.persistence.StorageAwareResourceDescriptionManager.getResourceDescription(StorageAwareResourceDescriptionManager.java:38) at org.eclipse.xtext.scoping.impl.DefaultGlobalScopeProvider.getVisibleContainers(DefaultGlobalScopeProvider.java:65) at org.eclipse.xtext.scoping.impl.DefaultGlobalScopeProvider.getScope(DefaultGlobalScopeProvider.java:49) at org.eclipse.xtext.scoping.impl.DefaultGlobalScopeProvider.getScope(DefaultGlobalScopeProvider.java:61) at org.eclipse.xtext.scoping.impl.AbstractGlobalScopeProvider.getScope(AbstractGlobalScopeProvider.java:49) at org.eclipse.xtext.scoping.impl.AbstractGlobalScopeDelegatingScopeProvider.getGlobalScope(AbstractGlobalScopeDelegatingScopeProvider.java:46) at org.eclipse.xtext.scoping.impl.AbstractGlobalScopeDelegatingScopeProvider.getGlobalScope(AbstractGlobalScopeDelegatingScopeProvider.java:42) at org.eclipse.xtext.scoping.impl.ImportedNamespaceAwareLocalScopeProvider.getResourceScope(ImportedNamespaceAwareLocalScopeProvider.java:97) at org.eclipse.xtext.scoping.impl.ImportedNamespaceAwareLocalScopeProvider.getScope(ImportedNamespaceAwareLocalScopeProvider.java:90) at org.eclipse.xtext.scoping.impl.ImportedNamespaceAwareLocalScopeProvider.getScope(ImportedNamespaceAwareLocalScopeProvider.java:88) at org.eclipse.xtext.scoping.impl.AbstractDeclarativeScopeProvider.delegateGetScope(AbstractDeclarativeScopeProvider.java:72) at org.eclipse.xtext.scoping.impl.AbstractDeclarativeScopeProvider.getScope(AbstractDeclarativeScopeProvider.java:104) at org.osate.xtext.aadl2.ui.propertyview.CachePropertyLookupJob.lambda$0(CachePropertyLookupJob.java:119) at org.osate.xtext.aadl2.ui.propertyview.CachePropertyLookupJob$$Lambda$32/2146769979.apply(Unknown Source) at org.osate.xtext.aadl2.ui.propertyview.AadlPropertyView$15.run(AadlPropertyView.java:2193) at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.runExclusive(TransactionalEditingDomainImpl.java:328) at org.eclipse.emf.transaction.util.TransactionUtil.runExclusive(TransactionUtil.java:328) at org.osate.xtext.aadl2.ui.propertyview.AadlPropertyView.safeRead(AadlPropertyView.java:2188) at org.osate.xtext.aadl2.ui.propertyview.CachePropertyLookupJob.run(CachePropertyLookupJob.java:223) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

This is due to a bug in xtext. It's fixed in 2.8.4.
