Liferay 6.11 failure on Import of Articles with multiple Versions

[Bogoy Hafner, modificado 11 Anos atrás.]

We seem to have an issue with importing articles with multiple versions in liferay 6.11

Caused by: com.liferay.portlet.journal.DuplicateArticleIdException
at com.liferay.portlet.journal.service.impl.JournalArticleLocalServiceImpl.validate(JournalArticleLocalServiceImpl.java:3565)
at com.liferay.portlet.journal.service.impl.JournalArticleLocalServiceImpl.validate(JournalArticleLocalServiceImpl.java:3546)

This error occurs during the import (data strategy copy as new).

I've stepped through the code with a debugger (netbeans), and it seems when liferay tries to import the second version of an article, it does not generate a new Id (which is fine - as its the same article Id), but validates if there is already an article with the same article Id and group Id present... which of course it is, as its just a different version of the article.

	protected void validate(
			long companyId, long groupId, long classNameId, String articleId,
			boolean autoArticleId, double version, Map<locale, string> titleMap,
			String content, String type, String structureId, String templateId,
			boolean smallImage, String smallImageURL, File smallImageFile,
			byte[] smallImageBytes)
		throws PortalException, SystemException {

		if (!autoArticleId) {
			validate(groupId, articleId);
		}

		validate(
			companyId, groupId, classNameId, titleMap, content, type,
			structureId, templateId, smallImage, smallImageURL, smallImageFile,
			smallImageBytes);
	}</locale,>

I can reproduce this by:

1) Unzip liferay 6.11 tomcat bundle.
2) create a community
3) backup installation
4) create an article
5) change and publish that article
6) Export the community pages
7) restore previous backup
8) import the exported lar
=> error

This seems like a bug to me, but I can't imagine, the import has not been tested with multiple versions of articles... so maybe I'm doing something completely wrong or misunderstanding something?
