Re: [go-nuts] Cannot unmarshal array into Go value...

[Jeff Hodges]

Looks like its the trailing "," in the inner-most map that's the
problem (that is, `"value": 1,` and `"value" : 2,`). The parser could
probably handle this case better and if you could make an issue, that would
be nice.

I'm not sure how you're generating this json, but, if you have control
over it, consider clearing up those trailing "," as they are invalid
json.

Thanks for your help, but the in the real JSON I'm parsing unfortunately there are no trailing ",". I just forgot to remove them.

The json isn't valid. There shouldn't be trailing commas.

It's a good idea to provide the code that you've written so we can
point out where the problem is.
Here is an example of unmarshaling your json.

Thanks for the example. Actually I've never thought of using plain interface{} for deserializing JSON. I tried to use structs, but this seems to be much simpler, so I'm going to use just this.
