Another glitch with PHP < 5.2.x

[kmeirlaen]

Apparently, older PHP versions have problems with typed parameters which have a default value. Or null doesn’t qualify as being of the correct type. either way I receive an error:
Fatal error: Argument 3 must not be null in /var/www/html/includes/qcodo/_core/framework/QQuery.class.php on line 119

The line looks like:
public function GetColumnAlias?(QQueryBuilder $objBuilder, $blnExpandSelection = false, QQCondition $objJoinCondition = null) {

Changing this to the following fixes the problem. Not sure if it is the “nice” way to fix it, but it works for me…
public function GetColumnAlias?(QQueryBuilder $objBuilder, $blnExpandSelection = false, $objJoinCondition = null) {

—-—-—-

Similar issues creep up with other methods in the same file…
