Vtiger 7 Webservice calculate totals

Hi, When calling the webservice to create a Quote or SalesOrder, the created record has not the totals calculated, it appears to be set to 0. The issue can be fixed by editing the file VtigerLineItemOperation.php and removing the first IF after the function getAllLineItemForParent starts. This condition doesnt make sense because right after said condition there is another condition that correcctly covers both cases that is if $parentId is_array or !is_array Please issue a fix for this Thanks
