/**
* This method checks if there is any data prepared for record or it uses
* default data based on type of the field.
*
* It looks for data for each field in record in following order:
* 1. Checks if data is set in DataObject
* 2. Checks data from data container (@see setData())
* 3. Checks data from $defaultValues variables defined in each DataObject
* 4. Generate data based on type of the field
*
* It populates primary keys fields only if data for key field was specifically
* set using any of methods defined in 1, 2 or 3 (it doesn't
* populate it with default data based on field type)
*
* @param DataObject $do DataObject to populate data in
* @param int $counter Used to generate a key for data container array to retreive data
* @access package private
