  public function mA()
  {
    Yii::app()->db->beginTransaction();
    ..
    ..
    Yii::app()->db->currentTransaction->commit();
  }
}

AND

Class B
{
  public function mB()
  {
    $a=new A();
    Yii::app()->db->beginTransaction();
    ..
    ..
    $a->mA(); //error occured
    ..
    ..
    Yii::app()->db->currentTransaction->commit();
  }
}

with TransactionHelper write the above code like below :

Class A
{
  public function mA()
  {
    $trans_key=TransactionHelper::beginTransaction();
    ..
    ..
    TransactionHelper::commit($trans_key);
  }
}

Class B
{
  public function mB()
  {
    $a=new A();
    $trans_key=TransactionHelper::beginTransaction();
    ..
    ..
    $a->mA(); //no error , transaction will not commit here
    ..
    ..
    TransactionHelper::commit($trans_key);
