Help: Object [object Object] has no method '_doesNotUnderstand_'

I will take a look when I get into work, this can perhaps be related to the fact that:

1. The exporter (fileout) exports whatever is loaded (independent of preceding filein)
2. The importer (filein) just overwrites, it does not remove all things in given package/class.
3. amberc imports and then exports, since import implies compilation.

Thus - if you introduce a class, and then remove it (or a method) it will be removed in st src, but can linger in js fileout! Not sure why it does not linger in st though.

This bug was discovered just a few days back and I/we haven't had time to fix it.

You can probably do surgery on js files to fix it.

Did you really say freshly cloned? Oh, hmmm. Then I am not sure, sorry for rambling. Did you clear chrome cache? I have noticed in another context that shift-reload does not always help.

Very strange problem, hoping someone can help. 

I can cold boot, cd into a freshly cloned amber directory, and ./bin/server. When I attempt to Try a class browser at localhost:4000/, Chrome console gives me...

I've been doing Amber dev on this machine for a couple weeks. The Object in question is of className "Recipe", which is a class I've created in the past, definitely didn't expect it to come into play here! In fact, I think it's long gone.

Is there something I don't understand about node.js? caching? I didn't clean something up properly?

Thanks,

Joel

I don't think so. Didn't do anything differently than Getting Started suggests. The node server provided just commits to file, correct?

The last thing I was working on was pulling json from a local CouchDB instance. I believe it was fine when I went to bed, and was broken when my machine woke back up 24 hours later. I neglected to shut down the node server during that time, which made me think that node might have gotten corrupted somehow over time, or as it attempted to run as my machine was coming in and out of sleep. Just speculating...
