Issue in adding a binding

Steps to reproduce:

• Add two Rectangle components to 2D View, rectangle1 and rectangle2
• Change the fill color of rectangle2
• Select rectangle1 and click + in Connections - Bindings
• Select To: rectangle1 color -> this works
• Select From rectangle2 color -> this does not work, there is no color option to choose
• Adding binding from Properties view -> action icon beside fill color -> add binding works if user types rectangle2.color but there are no options in the dropdown menus.
• Some bindings, e.g. bind rectangle1.x to rectangle2.x seem to work
