Hi Ignition,

Just wondering if you guys have any input about this error. I have a button that will pass a dataset to a custom property on a different window when clicked, and every time i tried to save the project, this error pops up.

SerializationException: Error during serialization for property ‘interactionController’ on object ‘[FPMIWindow]display’
caused by SerializationException: Error during serialization for property ‘generalAdapters’ on object ‘[DefaultInteractionController]com.inductiveautomation.factorypmi.application.binding.DefaultInteractionController@8a8930’
caused by SerializationException: Error during serialization for property ‘data’ on object ‘[PMITable]PMITable[Table]’
caused by TypeError: unhashable type: ‘list’

Ignition v7.7.1 (b2014092209)
Java: Oracle Corporation 1.7.0_71

Your inputs will be highly appreciated.

Thanks.

When you save a windows, contents of dataset are serialized to be saved
Perhaps something about the contents of you dataset ?

Yes, perhaps a list is in the dataset and shouldn’t be.
