Today I updated my Dynamo version to the latest one (0.9.1.4062), since then the floor types, wall types, levels, family types and some other nodes (all with a dropdown menu) don’t seem to work anymore. Did anyone else encounter this problem?
Checked with the 0.9.1 stable release. Works fine.
Try reinstalling.
I did as you suggested, it seems to work fine now. In the meantime I ran the previous version of Dynamo yesterday and I encountered the same problem just once. After restarting my pc it worked fine again… Maybe a bug?
