QuikTerminal, ProcessTask

Так как для QuikTerminals нет Builder, пришлось хранить IsProcessTaskInUse в QuikTransactions

<QuikTransactions>
  <Name>Quik Transactions</Name>
  <Code>Quik Transactions</Code>
  <IsEnabled>true</IsEnabled>
  <IsEvlEnabled>true</IsEvlEnabled>
  <Category>Transactions</Category>
  <Entity>Transaction</Entity>
  <!-- Need for QuikTerminal -->

  <IsProcessTaskInUse>false</IsProcessTaskInUse>

</QuikTransactions>

Достается в QuikTerminal так:

Transactions = Builder.Build<QuikTransactions>(@"Init\QuikTransactions.xml", "QuikTransactions");
Transactions.Parent = this;

IsProcessTaskInUse = Transactions.IsProcessTaskInUse;      

SetupProcessTask();

private void SetupProcessTask()

        {

            if (!IsProcessTaskInUse)

            {

                Evlm2(EvlResult.WARNING, EvlSubject.TECHNOLOGY, ParentName, Name,

                MethodBase.GetCurrentMethod().Name, "ProcessTask Will NOT BE USED",

                ToString());

                return;

            }

            

            ProcessTask = new ProcessTask<IEventArgs1>();

            ProcessTask.Init();

            ProcessTask.TimeInterval = 1000;

            ProcessTask.Parent = this;

            ProcessTask.IsEveryItemPushProcessing = true;

            ProcessTask.ItemProcessingAction = args =>

            {

                try
