Bug with multi-word Ref models.

Hi,

Found a bug with a case where a ref uses points to multi-word model (camelCase). The formage new/edit button next to the combo-box uses the label, not the model name, to generate the edit url. This causes the popup to contain an error, instead of submodel edit form.

Please review attached, there may have been a reason I am not aware of for you using the label?

Cheers
