After playing around more with the example on the php site: http://www.php.net/manual/en/language.oop.newref.php I tried doing this with out the factory: $dg =& new Structures_DataGrid(20); And everything seems to work except for the data, but i think that is a bug somewhere because I am getting the paging data before calling any render methods.

Yep, it was a bug! Instantiate SDG as a reference allows everything to work. I don't totally understand it at the moment, but it works! I am going to check the code into CVS, can you test it on PHP5?

It works fine in both PHP4 and PHP5 (no warning in E_STRICT mode). I find this kind of "=& new" syntax weird : with a factory it's always needed to use the & operator so it's coherent, but with a constructor it's an exception required by 1 package among 10. Anyway, the good point is that in PHP5 it works fine wether you use "=" or "=&". So, it gets coherent : using "=&" is a workaround for a PHP4 bug/limitation. -- og
