Exception on sync settings page

[Daniel Zoller]

javax.el.ELException: Cannot coerce from class java.util.ArrayList to class [Ljava.lang.String;

[Sebastian Böttger]

I cannot reproduce this error. Do you mean this page /settings?selTab=4#selTab4 ?

[Daniel Zoller]

Yes, please add a sync server to your system!

[Viktor Hemsen]

i can't reproduce this either.. i've tried to add a sync-server/client to biblicious via admin-page, and also add one on the settings page and that exception didn't show up. what exactly did you do?

[Daniel Zoller]

I can reproduce the error on our test system. Please note that you do not get an error page but a not complete (missing footer) rendered settings page. Here is the error message from the logs:

#!
