How to handle the "Your Spotfire session closed unexpectedly" error message

[Pierre Burrus]

Hello,

When I open a Spotfire project that used to work, I have the following error message : "Your Spotfire session closed unexpectedly". So that I am not able to open and modify the Spotfire project anymore. Does anyone know what could explain such a message

Thank you in advance,

Pierre

PS : the detailed message is as follows : "System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: An item with the same key has already been added."

Hi Pierre

First I would update to the latest hotfix and test it again to see if this has been fixed, if not please submit a case to support so that it can be looked into, attach the file and how to reproduce the issue.
