java.lang.ClassCastException sometimes when pins of a part are connected only to each other
amstan opened this issue · comments
I've been working on some complex importing from kicad. The importer is not finished yet, so I have some malformed schematics (ex: stuff isn't all the way connected).
I came upon this error:
java.lang.ClassCastException
Then nothing, the svg file just contains "undefined".
Are there any good ways to start a debugger on this?
I'm still use nodejs ~/netlistsvg/bin/netlistsvg.js --skin ~/netlistsvg/lib/analog.svg out.json to run netlistsvg.
I tried to simplify my file to track down the problem. One of the problems is on U3.

It has to do with net number 12 (connected to pins A6 and A7). If I connect power_symbol_15 to it (s/112/12), then it renders without errors.
Oddly this works (a smaller example)
