"odd number of parameters"

[asicerik]

Hello -
I am trying to use AddVertexByStruct with manually created properties. It works fine with single valued properties. If I try to add multiple values it fails with the "odd number of parameters" error.

Here is the code I am using to create the properties:
props := make([]model.Property, slice.Len())
for j := 0; j < slice.Len(); j++ {
props[j] = grammes.NewProperty(graphName, slice.Index(j).Interface())
}
vertex.Value.Properties[graphName] = props
Am I doing this wrong, or is there a bug?
I think this is because it creates the parameter strings using the key + values where it should put the key in every time.
The code in question is:
for key, vals := range vertex.Value.Properties {
properties = append(properties, key)
for _, val := range vals {
properties = append(properties, val.Value.Value.Value)
}
}

This will result in a string like "key", "val1", "val2", etc. instead of "key", "val1", "key", "val2" which is what AddVertex seems to expect.
