Re: [xwiki-devs] how to debug hibernate error at profile save?

I'm not fully sure, but this may be caused by the fact that the 'users' property of your object (XWikiRights I guess) was previously saved with a different data type. Probably something like xwikidoc <-- xwikiobjects <-- xwikiproperties <-- xwikistringlists vs. xwikidoc <-- xwikiobjects <-- xwikiproperties <-- xwikilargestrings

So when XWiki tries to save the 'users' property it sees that it has a different type (so different database table) than the previously saved value and thus it throws an exception. Try to pass a list/array as the value of the property instead of a string.
