Tag loads as Null

Hello,

We are using FlowChart.NET 5.0.1, and in our program we use tags that are objects, not strings; our program uses the diagram.SaveToString() method to save the tags.  When the program tries to load a saved project, we load the tags using the diagram.LoadFromString() method, but the tags come back null.  Any ideas of how to fix this or why it is happening would be appreciated.

Hello,

Mark the class of your tag objects as [Serializable]. Also implement the ISerializable interface if you plan to change that class in the future - that will let you realize some versioning logic for backward compatibility.

I hope that helps,
Stoyan
