I shall try and dig out the code i tested at the time.
If not the GtkList Object is easily created from one of the demos. I
shall add the callback function and see how i get on.

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

Does this still occur with newer versions?

Description:
------------
While designing a Till system using php gtk2 and grabbing code from
several examples. I encountered the following problem.
When clicking on an item in a GtkListStore object, the callback
function is either renamed/ stored incorrectly.

Despite me renaming it several times the function name is not handled
properly and causes characters to be misinterpreted.


$sectionBasketView = GtkListStore( Gtk::TYPE_STRING, Gtk::TYPE_LONG,
Gtk::TYPE_DOUBLE);
.
.
    $selection = $sectionBasketView->get_selection();
    $selection->connect('changed', "on_selection");
.
.
function on_selection()
{
.
.



Expected result:
----------------
on_selection function execution


Actual result:
--------------
The error log shows that the 9th character is pushed up by 1 character
code.
Here is a report from the error.txt it produced.
The first instance the letter "t" being replaced with a "s" character.
The second instance "i" renamed the function call with a "j" at the
start
this in turn affected the next character "c" changing to a "b".
As far as i can tell the on_selection is not used anywhere else.
Is this an inbuilt command/event/property?
