How Can I Initialize Runtimeconnection For My SSIS Dataflow Component From My IDtsComponentUI Correctly?

I am developing SSIS dataflow component.
Extended user interface is based on class IDtsComponentUI. Connection properties are created in both standart and my extended editor (Extended user interface). To set up designtime connection I use standart and my extended editor.


A main PipelineComponent component have two runtime connection:


IDTSRuntimeConnection90 adoConnection1 = ComponentMetaData.RuntimeConnectionCollection.New();

adoConnection1.Name = "Connection 1";

IDTSRuntimeConnection90 adoConnection2 = ComponentMetaData.RuntimeConnectionCollection.New();

adoConnection2.Name = "Connection 2";
----------------------------------------------------------------------


IDTSComponentMetaData90 dtsComponentMetaData; // current designtime component
....
In IDtsComponentUI I use follow fragment of code (for example):


_dtsComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager =

Microsoft.SqlServer.Dts.Runtime.DtsConvert.ToConnectionManager90(_connections[0]);

to set up IDTSRuntimeConnection90[0] connection using connections from a current package. After this operation
the RuntimeConnectionCollection[0] is not null within the method PipelineComponent.AcquireConnections((object transaction)). ! But during next launching of Extended user interface the RuntimeConnectionCollection[0] is null within the method PipelineComponent.AcquireConnections((object transaction)).
Why do I lose the connection? And why the connections which set up in my Advanced editor do not save in standart editor?


Thanks in advance.
