SV: [Phpgroupware-developers] Coding Assistance

[Sigurd Nes]

Assuming the XSLT template:
First of all - you have to include your app in the
$GLOBALS['phpgw_info']['flags']['xslt_app']

This is (temporarily) done in '/phpgroupware/index.php' - look for
'switch($app)' at line 58 - and include your application.

Also - in order to have the _debug_array($array) function to work (great
for debugging) - you will have to set 
$GLOBALS['phpgw_info']['server']['support_old_style_apps'] = False; in
'header.inc.php'

Have a look at the app 'property' (in HEAD) - which also is built from
'notes'.
