                 * in order to solve the bug 0004389, we use the validation function Exists
                 * inside the remove function in order to verify if the DbSource record
                 * exists in the Database, however there is a strange behavior within the
                 * propel engine, when the first record is erased somehow the "_deleted"
                 * attribute of the next row is set to true, so when propel tries to erase
                 * it, obviously it can't and trows an error. With the "Exist" function
                 * we ensure that if there is the record in the database, the _delete attribute must be false.
                 *
                 * note added by gustavo cruz gustavo-at-colosa-dot-com 28-01-2010
                 * I have just identified the source of the issue, when is created a $oDbSource DbSource object
                 * it's used whenever a record is erased or removed in the db, however the problem
                 * it's that the same object is used every time, and the delete method invoked
                 * sets the _deleted attribute to true when its called, of course as we use
                 * the same object, the first time works fine but trowns an error with the
                 * next record, cos it's the same object and the delete method checks if the _deleted
                 * attribute it's true or false, the attrib _deleted is setted to true the
                 * first time and later is never changed, the issue seems to be part of
                 * every remove function in the model classes, not only DbSource
                 * i recommend that a more general solution must be achieved to resolve
                 * this issue in every model class, to prevent future problems.
