Patch is mostly created by script in egroupware/doc/fix_depricated.php in separate commit. I do NOT advice to apply this patch to a production system (it's commited to trunk!), as the automatic modified regular expressions have a good change to break something ...

|
|
* AJAX Select Widget
|
|
*
|
|
* Using AJAX, this widget allows a type-ahead find similar to a ComboBox, where as the user enters information,
|
|
* a drop-down box is populated with the n closest matches. If the user clicks on an item in the drop-down, that
|
|
* value is selected.
|
|
* n is the maximum number of results set in the user's preferences.
|
|
* The user is restricted to selecting values in the list.
|
|
* This widget can get data from any function that can provide data to a nextmatch widget.
|
|
* This widget is generating html, so it does not work (without an extra implementation) in an other UI
