IndexOutOfRangeException On Deserilazing A Saved Flow

 Hi ,

I just implemented Dynamically adding Connection points feature in my diagram nodes. After that i started to get IndexOutOfRangeException when opening the saved diagram. I guess FromIndex or ToIndex of Connection data that is seen in serialized connection xml causes this exception.

<Connection ID="044a212b-3e1b-47a9-86a7-cc73adc2e7cd" From="139b9679-88b3-48b8-99f6-ca7c27b26a38" FromIndex="2"

But I dont know how to solve or what is the problem. I am deciding to add new connection points at runtime by looking the connection counts of connection points. if all outbound connection points has at least one connection then i add new connection point. Also this logic runs when deserializing diagram but it causes index out of range exception.

Hello

Would you be able to send us a small sample showing this problem? I should be able to find a solution by looking at exactly how you are adding more connection points and how you are currently handling deserialization. If you can send a sample, either send it in a forum post, or send it to jason@mindscape.co.nz

I changed the logic . Instead of adding more connection points , I enabled one connection point to have multiple connections. and the error gone.

It would be really useful if you could post how you changed the connection points to have multiple connections.

Many thanks,
David

public  class IndexedConnectionPoint : OutboundConnectionPoint

{
	public IndexedConnectionPoint(FlowDiagramNode node, Edge
		 edge) : base (node, edge)
 
	{
 	}
 
 	public override bool  CanOriginateNewConnections 
 
	{  
		get 
		{  
			return true; 
 
		} 
	}  
}
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
I Defined a new Connection point class from deriving OutboundConnectionPoint and 
I overrided the CanOriginateNewConnections property to return true always. this way 
my connection points allow multiple connections start from them. Is it wrong ?
