When saving a Spotfire document from an environment where Lead Discovery is not installed, if it was created from one of the default files (/Discngine/Client Automation/empty or /Discngine/Pipeline Pilot Data Functions/empty), you may encounter a "Disposed" error that prevents the document from being saved.
Details
This issue occurs because the Lead Discovery extension is not available in the environment, and the empty documents we provide in releases 6.1.0 and earlier contain references to Lead Discovery components. When attempting to save the document, Spotfire tries to access these components, leading to the following error:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.Serialization.SerializationException: Attempt to read from a node that is in state 'Disposed': Spotfire.Dxp.Framework.DocumentModel.State.DisposedUndoablePropertyNodeState`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].
Object reference chain leading to the fault (closest reference first):
Spotfire.Dxp.Application.CustomNodeStandIn.Table
Spotfire.Dxp.Application.CustomNodeStandIn.Tables[0]
Spotfire.Dxp.Application.CustomNodes.Nodes[0]
Spotfire.Dxp.Application.Document.CustomNodes
---> System.InvalidOperationException: Attempt to read from a node that is in state 'Disposed': Spotfire.Dxp.Framework.DocumentModel.State.DisposedUndoablePropertyNodeState`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].
Resolution
Starting with release 6.1.441, we provide empty files that do not include references to Lead Discovery components. We strongly recommend using these updated empty files to create new Spotfire documents (this must be done by a Spotfire administrator following the import library step of the installation guide).
However, if you are using an older version of the Spotfire Connector for Pipeline Pilot or if you have already created a document based on the previous empty file, you have the following options:
- Recreate the Spotfire document based on one of the updated empty files provided in release 6.1.441 or later.
- Install the Lead Discovery extension on the system where you are saving the document. This will ensure that all components referenced in the document are available, allowing you to save it without errors.
