* It's inspired by the code from Klaus Leithoff, which does the same thing limited to addressbook.
|

*
|
|
* The schema of the custom fields table should be like (the lenght of the cf name is nowhere enfored and
|
|
* varies throughout eGW from 40-255, the value column from varchar(255) to longtext!):
