Yet another juicy Alfresco Labs 3.1 stacktrace...

...which kept me busy for a couple of days.
I dumped it here for in case somebody else hits it.
So if you didn't find this post by googling an alfresco exception, you need to move along people, there is nothing to see here.

Without further ado, if you get the following exception:

javax.faces.FacesException: javax.faces.FacesException: Could not retrieve value of component with path : {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /jsp/dialog/container.jsp][Class: javax.faces.component.html.HtmlForm,Id: dialog][Class: javax.faces.component.UINamingContainer,Id: dialog-body][Class: org.alfresco.web.ui.common.component.UIPanel,Id: users-panel][Class: org.alfresco.web.ui.common.component.data.UIRichList,Id: users-list][Class: org.alfresco.web.ui.common.component.data.UIColumn,Id: _idJsp33][Class: javax.faces.component.html.HtmlOutputText,Id: _idJsp35]}

nice, hey.

I think its reported here
https://issues.alfresco.com/jira/browse/ETHREEOH-1846

To fix it, I built a newer version of org.alfresco.repo.search.impl.lucene.ADMLuceneIndexerImpl from the svn sources, and dumped it in the alfresco/WEB-INF/classes and it works!
