Error with Decision Tree : No tree data set exists. Either run the tree node or create a tree data

Hi !

I'm trying to migrate a project from EM 6.2 to EM 14.1. The project has been migrated successfully but when i run the diagram, I encounter error in Decision tree nodes that have "Use Frozen Tree" property = "Yes". The end of the log for the node will have something like this:

* ERROR: No tree data set exists. Either run the tree node or create a tree data set in Interactive Training.

Anyone encountered this ? or know any fix? Thanks !

Sarah

Try doing this: set the Import Tree Model property to Yes, then select the Tree Model Data Set - it should be in the diagram workspace folder (EmwsX) for your current diagram, called Tree_EMTREE or TreeZ_EMTREE for a number Z if you have multiple Decision Tree nodes. This should do the same thing as using the frozen tree. Hope that helps!
