我装的all in one （object web）在建立动态网页项目时还要报错：
IWAE0010E Run-time exception java.lang.ClassCastException occurred during validation. The validator being run was War Validator and the message thrown was org.eclipse.wst.common.componentcore.internal.ModuleStructuralModel cannot be cast to org.eclipse.wst.common.componentcore.internal.ArtifactEditModel.
如何是好?
请大虾指点，谢谢
