[sync] SyncML broken with latest Horde Webmail 5.2.22 ?

[Christian Bomhardt]

Hi Friends,

I just upgraded to Horde Webmail 5.2.22 with php7 (from 5.2.16?). My 
used Android SyncML Client (ChBoSync) doesn't work any more - with 
Webmail 5.2.21 as installed on demo.horde.org, it still works. So issue 
could either be related to Horde Version or underlying Linux/php.

What I figured out so far via Debugging:

Some errors are logged trying to call non-static methods. To fix it, I 
did the following:

In Horde_SyncML_Backend.php: make factory method static

In Horde_SyncML_Command.php: make factory method static

In Horde_SyncML_XmlOutput.php: make singleton method static


Now I have this issue and don't know how to fix it - seems like the 
issue is in the ContentHandler.php, line 119 => 
$this->_xmlWriter->init(new Horde_Xml_Wbxml_ContentHandler());

Any ideas how to fix/patches ?

Thanks a ton,
  Christian
