Possibly a hack, not sure:
Add a workflow that has a condition--check the structure Id. If it's
the structure you need a notification for, transition to a state node
that has two jobs: send a notification and transition the item to the
end state (where you should makr the item as approved). If it's not
the structure you're interested in, just transition directly to the
end state node (where you mark the item as approved).
Condition could look something like this:
import com.liferay.portal.kernel.workflow.WorkflowConstants;
import com.liferay.journal.service.JournalArticleLocalServiceUtil;
import com.liferay.journal.model.JournalArticle;
import com.liferay.portal.kernel.util.*;
long id = GetterUtil.getLong((String)workflowContext.get(WorkflowConstants.CONTEXT_ENTRY_CLASS_PK));
JournalArticle ja = JournalArticleLocalServiceUtil.getJournalArticle(id);
if (ja.getDDMStructureId() == 34888) {
returnValue = "fe262ad3-1b44-42d3-b790-f5c23679492a";
}
else {
returnValue = "09ef78d1-daab-4d5b-81c0-bb92f92435c8";
}
