如果我尝试通过事务编辑域I am getting exception as
修改该资源文件,那么我在资源管理器中有资源文件
java.lang.IllegalStateException:无法修改资源集 写交易 org.eclipse.emf.transaction.impl.TransactionChangeRecorder.assertWriting(TransactionChangeRecorder.java:348) 在 org.eclipse.emf.transaction.impl.TransactionChangeRecorder.appendNotification(TransactionChangeRecorder.java:302) 在 org.eclipse.emf.transaction.impl.TransactionChangeRecorder.processObjectNotification(TransactionChangeRecorder.java:284) 在 org.eclipse.emf.transaction.impl.TransactionChangeRecorder.notifyChanged(TransactionChangeRecorder.java:240) 在 org.eclipse.emf.common.notify.impl.BasicNotifierImpl.eNotify(BasicNotifierImpl.java:374) 在 org.eclipse.emf.common.notify.impl.NotificationImpl.dispatch(NotificationImpl.java:1027) 在 org.eclipse.emf.common.notify.impl.NotifyingListImpl.addUnique(NotifyingListImpl.java:299) 在 org.eclipse.emf.common.util.AbstractEList.add(AbstractEList.java:303)

我认为问题在于,您正在尝试在另一个写入事务中执行写入事务。命令应该可以解决问题。这可以使用模型的EditingDomain
来完成:(确保org.eclipse.emf.transaction
在您的依赖项中)
import org.eclipse.emf.transaction.TransactionalEditingDomain;
import org.eclipse.emf.transaction.util.TransactionUtil;
public void doEditing(EObject element) {
// Make sure your element is attached to a resource, otherwise this will return null
TransactionalEditingDomain domain = TransactionUtil.getEditingDomain(element);
domain.getCommandStack().execute(new RecordingCommand(domain) {
@Override
protected void doExecute() {
// Implement your write operations here,
// for example: set a new name
element.eSet(element.eClass().getEStructuralFeature("name"), "aNewName");
}
});
}
