Features by category

[Eject-computer]

Hi, I'm trying to make that you can asign features to categories. I update AdminFeatuesController::RenderForm() and now it show a dopdown list with categories. When you create one feature it works fine, but when i edit an existing feaure it doesn't load the category inthe dropdown list. In the table view of all features, it shows category column, but, it doesn't the translation, and the field is empty.
