Hi, Please see the existing issue on our issue tracker (good place to look first): http://jira.xwiki.org/browse/XWIKI-13546 Thanks, Eduard On Mon, Jul 18, 2016 at 8:53 PM, myname <[email protected]> wrote:
Hi everybody, I've tried the whole afternoon (including checking the source code of the corresponding java files) but I was unable to resolve my problem by myself.
What have I done: * I've created a XWiki instance and I'm running 4 or 5 separate wikis there. * I've set up mail sending in the "main" section to test some features * The mails are sended and are received by the testclient
So far no problem. But if I'm looking into the console output I've got the strange exception with an error level there and I'm not able to solve it: 2016-07-18 19:41:52,401 [Mail Sender Thread] ERROR o.x.m.i.t.SendMailRunnable - Unexpected error in the Mail Sender Thread java.lang.IllegalArgumentException: An Entity Reference name cannot be null or empty at org.xwiki.model.reference.EntityReference.setName(EntityReference.java:187) at org.xwiki.model.reference.EntityReference.<init>(EntityReference.java:172) at org.xwiki.model.reference.EntityReference.<init>(EntityReference.java:143) at org.xwiki.model.reference.WikiReference.<init>(WikiReference.java:61) at org.xwiki.configuration.internal.AbstractDocumentConfigurationSource. getCurrentWikiReference(AbstractDocumentConfigurationSource.java:185) at org.xwiki.mail.internal.configuration.SendMailConfigClassDocumentConf

as far as I understand the message it tells me, that a mandatory property is missing, should be the waitSendWaitTime property.
In my mail configuration I've overridden the Send Wait Time, addtionally I've uncommented the property: mail.sender.sendWaitTime=8000 in the xwiki.properties file.
Unfortunately the error keeps occuring.
Best regards and thanks in advance, Heiko
