Error opening version 3.40 file in 4.20: could not open xstream for org.diylc.components.passive.ElectrolyticCanCapacitor

[mikevi...@gmail.com]

Hi

I am an infrequent user, so it was a long time between updates. I recently upgraded from 3.40 to 4.20. But now I cannot open any 3.40 files in 4.20. I can still open them in 3.40.

Regards

M

I should note - I can work around the issue by removing the can cap from the layout in 3.40, saving the file, then opening in 4.20. I then need to add the can cap back into the new 4.20 version.

Can you please upload one of the problematic files?

[Doug Hoffman]

I answered his email this morning and told him it is most likely that old multi section can cap that you deleted because it was not constructed properly

I also told him to dlete that cap and use one of the new cap can you created

Did you do what I said to do?
Look at your java error message

Caused by: com.thoughtworks.xstream.mapper.CannotResolveClassException: org.diylc.components.passive.ElectrolyticCanCapacitor

Delete that cap in 3.4, save the file, then open it in the new version and add a new cap

Hi

Happy Easter folks. 

I will jump in later today and confirm Doug’s fix. From my last trial, I could open 3.40, delete the multi section can cap, save then open the file in 4.20. 

If the multi section can cap has been moved to A different library then I suggest we close the issue. I will confirm I have a containment for the issue and I doubt this will be a big problem as not many people will have version 3.40 files. 

I will upload the layout file to the thread later today too. 

Cheers

Mike

Hello,

The procedure of opening with a previous version 3.4, removing the multicap can and adding the caps again in version 4.5 resolved the error opening the older file.

Thanks for the fix procedure.
