Note
When developers override "`kDBEventHandler::getPassedId`" method and manually call the `$this->Application->GetVar` method inside, then it's up to them to set the "`id_from_request"` event parameter.

In-Portal uses object automatic loading technique, that attempts to load an object with ID provided in Web Request (e.g. in URL). For example:

user opens /cars/japan/2013-suzuki-sx4.html url
based on this URL following is automatically detected:
1. this is "cars/japan" category
2. this is "2013-suzuki-sx4" product
the product detail template is shown
the product detail template contains <inp2:p_Field name="Name"/> tag that shows product name
the "Field" tag requested data from product object
the product object is created since this is a 1st request to that object
product object is loaded using "2013-suzuki-sx4" ID from Web Request

...

Solution

Plan for fixing:

make "kDBEventHandler::getPassedId" and "kDBEventHandler::StoreSelectedIDs" methods to set "id_from_request" event parameter to the "$event" variable, when ID was obtained from Web Request
in the "kDBEventHandler::OnItemBuild" event, when we're doing object auto-loading replace call to "kDBEventHandler::checkItemStatus" method with "true", when "id_from_request" event parameter is "false"
to reduce human error factor the "kEvent::ID_FROM_REQUEST" constant needs to be created and used instead of using "id_from_request" string
