	As in subject is shortly described, by adding a tag to diagram link there is going to be problem. I haven't tested it separately but in my case it clears all nodes from the diagram. (ClientSideMode=JavaApplet) I saved the diagram to a xml and I saw that the "tag" tag was something like this: <Tag Type="1" /> Br. Henry

	Hi, Is the link visible after loading the diagram? Are you handling the SerializeTag and DeserializeTag events? Is there any exception raised before the nodes disappear? Does the Java console show any relevant info about the problem?

Link visible after loading the diagram: nothing is visible (as I miserably described) Is there any exceptions raised before the nodes disappear: no, not from server side, at least not in any that try-catch can see.. Are you handling the SerializeTag and DeserializeTag events: no... Br. Henry

	Can you send us a small application that reproduces this problem? You can attach it here or send it to support@mindfusion.eu.

	I finally found the case. The tag that is generated is null/emptyString. ( <Tag Type="1" /> ) << is generated If this xml is loaded, the diagram will be empty (nothing is shown on the diagram). But when a postback or callback is made (when data is already loaded to session for example)... the data exists there (i.e. the nodes & links). In the attachment there is a XML file (in text extension, because of forum limitations) Br. Henry

	Hi, This version should fix this issue: https://mindfusion.eu/_temp/netdiag_applet.zip. Alternatively, you can reset the Tag value to null instead of assigning an empty string to it. Let me know if this helps.
